What are the four C’s of diamond quality?
Colour – 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.

Carat – refers to the weight of a diamond, instead of its dimensions.and cut.

Cut – determines the brilliance of a diamond. The better the diamond is cut, the more it sparkles.

What gemstones can I choose from?
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.

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.

Can I view the diamonds and gemstones before deciding on one?
Absolutely.  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.

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.

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?
No. All of our jewellery is bespoke and handcrafted so there is no additional cost for this service.

What designs can we choose from?
We offer a beautiful range of handcrafted finished rings from our engagement ring collection that are ready to wear however our team 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.

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. 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.

Are there other options for those who don’t want a diamond?
Yes, absolutely. We offer a wide variety of precious and semi-precious coloured gemstones in all shapes and sizes.

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 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 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.

I don’t know her finger size – what shall I do?
If your partner has a ring, place on a ruler to measure the internal diameter of the ring. Also, be sure to remember what finger she wears that ring on, so we can 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. 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.

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.

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 offer a 15% discount on wedding bands.

What designs can I choose from?
We have a wide selection of finished bands available to view in our atlier.

How far ahead should we book?
We recommend 3-4 months prior to your wedding day. 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.

Do you remodel pieces of jewellery?
Yes. We are privileged to reinvent inherited or generational jewellery for modern times.

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.


All of our  jewellery comes with a lifetime guarantee against faults in materials and workmanship. To ensure your jewellery 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 jewellery. Our guarantee covers any defect caused by faulty materials or workmanship but 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.

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.

Diamonds can 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.


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.
