What are the four C’s of diamond quality?
Each diamond is unique, and the four C’s is the universal method of assessing the quality of the diamond. Colour, clarity, carat and cut.
The colour grade refers to the lack of colour in a white diamond. A white diamond, with little to no colour, has a higher colour grade.
As natural diamonds are created under extreme heat and pressure deep in the earth, it often results in a variety of inclusions and blemishes. Clarity refers to the presence or absence of these imperfections, and their quantity and sizes.
Carat refers to the weight of a diamond, instead of its dimensions.
The cut determines the brilliance of a diamond. The better the diamond is cut, the more it sparkles.

What gemstones can I choose from?
As we specialise in bespoke designs, we can source a variety of different gemstones in different shapes and colours. Rohan hand picks every coloured stone himself, travelling the world to bring back the best of colour from some of the epicentres of gemstones.
Some gemstones we are most passionate about include sapphires, emeralds, rubies, garnets, tourmalines, Australian South Sea pearls and Argyle pink diamonds. We are renowned for our coloured gemstone collection, and love to personalise jewellery with a pop of colour by incorporating only the finest and most beautiful gemstones, personally sourced with love and care.

Do your diamonds come with certificates?
Yes. Majority of our larger diamonds come with independent internationally recognised certificates (e.g. GIA, GSL) which outline the details of the diamond. We do however grade all diamonds and cross reference with the certificates that accompany them. This is one of the most important aspects to purchasing a diamond or stone that have certificates. Our graders have the expertise to guide you to find the right stone that suits you. Our services are not just about the sales transaction of a diamond but, to guide you through the selection process and show you a number of gemstones that suit both design and budget.

Can I view the diamonds and gemstones before deciding on one?
Absolutely. Once again this is the key to finding the right gemstone for you. Without options it is hard to compare, so how would you know you have found the one? We love finding the gemstone that speaks to our clients, not necessarily the one that just looks good on paper. During a one-on-one design consultation, you can choose your diamond or coloured gemstone from a wide range of options. Our experienced team of jewellers and diamond graders will go through each gemstone with you and explain the differences. Often there is one that jumps out, and it is not always the most expensive or largest one.

What is fluorescence in diamonds?
Fluorescence refers to the tendency of a diamond to emit a coloured glow when subjected to ultraviolet light and is a natural characteristic of a diamond. It is classified as none, faint, medium, strong or very strong; and the most common fluorescence colour is blue.
GIA studies show that for the overwhelming majority of diamonds, the strength of fluorescence has no widely noticeable effect on appearance. In the case of diamonds with lower colour grade, such as J, K and L, the blue fluorescence can balance out the yellow tone of the stone, which makes the diamond appear whiter. In rare cases, some diamonds with extremely strong fluorescence may appear hazy or oily; fewer than 0.2% of the fluorescent diamonds submitted to GIA exhibit this effect.

Do you work with lab-grown or synthetic diamonds? 

No, this is not an area of the industry that we specialise in.

Does custom design cost me more?
This is a common question we get asked – what is the difference in price between creating a bespoke custom designed ring and choosing an existing ring from your collection? The answer is there is no difference in price. It will not cost you more for us to create and design a ring to your vision as all of our jewellery is bespoke and hand crafted. Hence, it is the same process for both options. This is what makes us unique in our offering. We are passionate about creating one-off designs for our clients.

What designs can we choose from?
We specialise in handcrafted, custom designed and custom-made jewellery. The sky really is the limit when it comes to a bespoke design, that is the fun part. We offer a beautiful range of handcrafted finished rings from our engagement ring collection that are ready to wear. If you are inspired by one of our rings and you would like to tweak the design slightly to make it truly your own, this is also an option. We have a team of talented designers and jewellers that can create something uniquely for you, and if you wish Rohan to be involved in your bespoke journey, just ask.

I already have a design in mind – can you make it for me?
Yes, absolutely. All of our engagement rings are custom made so you can sit with one of our designers and discuss all of your ideas. If you have any images, bring them along to help our designers see exactly what you are looking for. We can then sketch concepts for you to choose from. You are welcome to make adjustments to the sketches or choose one to your liking. Once you have chosen a design, we can provide a quote. This should be an enjoyable and incredibly special process, without worry.

What is the difference between Platinum and White Gold?
White gold is mainly a mixture of pure gold and palladium. It is this combination that we craft from. Not all white golds are the same, but white golds are rhodium plated which is a coating of one of the platinum group metals. This makes it wonderfully white. All white gold will require replating during its lifetime. Platinum is its own metal and we use a mix of pure platinum and ruthenium, which is another platinum group metal. Platinum does not need to be rhodium plated as it is very white in itself. It is also noticeably heavier than white gold, and hence has that added feeling of opulence. We specialises in the practice of platinum, even though it is harder to work with. Once again, ask the question – why white gold, not white gold.

Are there other options for those who don’t want a diamond?
Yes, absolutely. This is our happy place! We can certainly assist with different alternatives to a diamond. White and coloured gemstones are becoming increasingly popular for engagement rings. We offer a wide variety of precious and semi-precious coloured gemstones in all shapes and sizes. Our team of expert jewellers can help you with finding the right gemstone through our global network of trusted suppliers if we don’t have the right one for you already in our collection. Our jewellers can educate you on the different qualities and characteristics of each stone.

If we already have our diamond, can you still make the ring?
It is possible to use your own gemstone or diamond, however there is a surcharge for using your own stone and we will need to view the stone in person prior to confirming if we can work with it. There are times where the stone might not lend itself to the design, or the risk is too great where we may decline.  There are also stones that we will not work with such as moissanite, fracture-filled, lab-grown or synthetic diamonds.   While we take the greatest care when handling our client’s own stones,  we do not take responsibility for breakage or damage that could occur during the manufacturing process. We encourage you to make a time to discuss your ideas with our design team.

Can I buy just the stone and let my partner choose the ring later?
Yes, we know that sometimes it’s hard to know exactly what design to go with. So we can package up the diamond in a beautiful box for your proposal, then visit us in the boutique with your partner where your bespoke journey begins. What we have done many times is sketch up the proposed ring design, with your guidance, and we choose one you think they might like, and we can block mount it and wrap it up with the diamond. This way you are proposing with more than a loose stone and can share with your partner the intended design without the commitment of having the ring completely made.

I don’t know her finger size – what shall I do?
If your partner wears rings, try to see if you can sneak a photo of it on top of a ruler to measure the internal diameter of the ring. Also, be sure to remember what finger she wears that ring on, then we can make an estimated guess as to what the ring finger will be. If you cannot do this, or your partner does not wear rings, we can make the ring to an average finger size. Or, if you have a photo of their hand holding something for size relativity, Rohan can usually get a close estimate. Either way, we offer a complimentary ring resize in the first month if it is a surprise proposal.

How much does an engagement ring cost?
The price of an engagement ring will vary depending on the design you choose, the metal type required, and most importantly, the stone(s) you chose for your ring. This is a very tricky question and so it is best to have a chat with us, by booking a complimentary design consultation, and we can work out an estimate based on the above. The most important thing when it comes to purchasing a ring is that you feel comfortable with what you are spending.

How long does it take to have a custom made engagement ring made?
Depending on how complex the design is, our usual turnaround time is 3-4 weeks from when the final design and stones are confirmed.

Can I make changes to the design once you have started making my ring?
In most cases, small changes to the design before any stones are set can be made. This would include a change of finger size, profile of the band and width of the band, if the jeweller advises it is safe to do so.

Do you provide a guarantee on your engagement rings?
We pride ourselves on the high standard and quality of workmanship that goes in to making every engagement ring and piece of jewellery. All of our engagement rings and jewellery come with a lifetime guarantee against faults in materials and workmanship. To ensure your ring is safe to wear, you must bring in your piece of jewellery for an annual check. This is a complimentary service and is included with all of our engagement rings. Our guarantee covers any defect caused by faulty materials or workmanship. Our guarantee does not cover defects relating to general wear and tear, scratching, damage caused by accidents, neglect or misuse, or any resulting loss of the ring or precious stones from the ring. Engagement rings not custom made by us are not covered by the guarantee.

How much will they cost?
Prices range depending on finger size, style and whether the design is to be custom designed to fit an existing engagement ring. Materials and design combination is what will determine the pricing. For all clients that have purchased an engagement ring through us, we are delighted to offer a special 15% discount on wedding bands as a thank you.

What designs can I choose from?
We have a wide selection of finished bands available to view at our Perth city and Leederville boutique. You may also wish to view these on our website: Click for ladies wedding bands. Click for mens wedding bands. As all of our jewellery can be custom made, we can create something unique, and we invite you to share your vision and ideas with us too.

How far ahead should we book?
We recommend 3-4 months prior to your wedding day. It usually takes around 4 weeks, but we will always try to accommodate if you have shorter deadline. We encourage you to book a complimentary design consultation with one of our jewellers to discuss all of your options.

Will my wedding ring match my engagement ring?
We will ensure your wedding band matches perfectly with your engagement ring. We normally require you leave your engagement ring with us and will call you when its needed for the making process to ensure the dimensions match exactly.

I don’t live in Perth, can I liaise with you via phone/email to have a piece designed? Do you post?
We have many national and international clients. We understand the difficulties in getting to our boutiques and hence, we are very adept at phone / email liaising on design and stone selection. We still go through the same process as if you were in store. We will look at a number of options before selecting the one that suits the design and the budget. We then take progress shots in our workshop so you can see the piece come to life. Once again, we are professionals who love what we do and just because you are not here, we take even greater pride that you trust us.

Do you remodel pieces of jewellery?
Yes. We are privileged to reinvent inherited or generational jewellery for modern times. From vintage jewellery to engagement rings – pieces that symbolise past eras or hold sentimental value. We welcome you to visit our boutique for a complimentary design consultation to discuss your options in remodelling a piece of jewellery. Our friendly team of designers will suggest new design concepts as well as work with your ideas and draw up sketches to assist you with envisioning the piece before it goes into the workshop. Our team of jewellers will assess the piece for any possible risks. Some precious metals cannot be melted and reused and some diamonds and gemstones will require revitalisation to bring them to their former glory before being reset into a new design.

Remodelling existing pieces of jewellery can reduce the cost partially if gemstones or metal can be reused. However, the labour involved in handcrafting can sometimes be significant, therefore the saving is not always as great as people might expect, but the sentimental value will be priceless.

Bespoke Fine Jewellery

We specialise in custom-made handcrafted fine jewellery.
Imagination is the only boundary, as long as the design is technically possible and safe. Through a collaborative approach, our team of designers listen, think, plan, sketch, source gems and diamonds, and our finest craftsmen bring extraordinary custom creations to life, ensuring every piece is of exceptional quality. From engagement rings to wedding rings, pendant, earrings, bracelets, cufflinks and many more, using an array of coloured gemstones or diamonds, made with your choice of metal including white gold, yellow gold, rose gold, platinum, titanium and Damascus steel, the design process is so much fun. Our design consultations are complimentary, and we welcome you to make an appointment.

We take a great pride in the quality of our craftsmanship which comes with the Rohan Jewellers guarantee. All jewellery, particularly when worn daily, requires ongoing maintenance and care to ensure it remains in peak condition.

Every piece handcrafted by Rohan Jewellers comes with an ongoing care programme. We encourage you to bring in your jewellery to one of our boutiques for a complimentary professional service every 12 months, and once in the first 6 months after purchase.

The guarantee will be void if there are defects related to external damages, if it has been altered or repaired by another jeweller or has not been returned to a Rohan Jewellers boutique for a yearly service. When covered by guarantee, repairs are complimentary.

Caring for your Jewellery
All jewellery, particularly jewellery worn on a daily basis, requires ongoing care and maintenance to ensure it remains in peak condition. Your jewellery should be kept away from harsh detergents and hard surfaces (even a diamond can be chipped by a hard knock along its grain), hence it is best to remove your jewellery when:
-Undertaking heavy work with your hands, such as working out at the gym, heavy lifting and gardening;
-Carrying out domestic chores, particularly when using chemicals such as chlorine and bleach which will affect your jewellery finish and lustre.

Diamonds have an affinity to dirt and oil so keep away from moisturisers, oils and make-up but it can be cleaned easily and quickly at one of our boutiques, or at home with a soft toothbrush and a mild solution of 6 parts water and 1 part ammonia, or just some dishwashing detergent.

We recommend to bring in your jewellery once a year for an annual check, professional clean, polish and rhodium plate.

All white gold jewellery is rhodium plated to ensure a brilliant white finish. Rhodium plating will naturally wear over time, depending on the frequency of wear and other environmental factors. It should be replated once a year, which is a complimentary service at Rohan Jewellers for our pieces.

Any pearl jewellery requires a bit more care due to their soft nature.

Do not let your pearls come into contact with hairspray, cosmetics, sun creams and perfumes as these contain chemicals that can damage the nacre. To clean your pearls, simply wipe them with a soft, damp cloth to remove excess oils and dirt. Although pearls can be worn every day, it is advisable not to swim, shower, sleep or play sport whilst wearing them.
It is required to get them restrung once a year or as soon as they are showing signs of looseness.

Storing Your Jewellery
When you are not wearing your jewellery, be sure to store it in a protective box or pouch, away from other jewellery to avoid unnecessary scratches.

If you have knocked or dropped your jewellery, and you have, or think you may have damaged it, do not continue to wear it. Please bring it to us as soon as possible so we can conduct a full safety check to ensure there is no damage.

Above all, please be mindful that you are wearing a piece of fine jewellery, handcrafted from natural materials. While some of these materials are hardwearing, your jewellery should be treated with absolute love and care.
