Coloured Diamonds: Fancy Yellow Diamonds

All you need to know about naturally coloured diamonds

Naturally coloured diamonds are rare to come by. In fact, approximately 2% of all mined diamonds are coloured and only one in every 10,000 diamonds is certified as a fancy-coloured diamond. Not only are coloured diamonds highly collectable, they also make fine mesmerising jewellery.

Few other precious gemstones have been given such iconic status in history as fancy-coloured diamonds. A legendary yellow is the 101.29-carat fancy vivid yellow Allnatt Diamond, which was discovered in a South African mine around 1880. Its first known owner entrusted it to Cartier in the early 1950s to be set into a brooch.

While these rare diamonds come in a few different colours including blue and pink, fancy yellow seems to be the desired colour of the moment. Keeping up with this bold fashionable trend, all you have to do is get a little adventurous and dare to flaunt a diamond that isn’t just of a pure colourless grade.

A number of wealthy individuals have already jumped on the bandwagon and procured a collection of truly rare sparkles from Queens to celebrities. Fine connoisseurs and billionaires wear their coloured diamonds with pleasure while also realising that it is a great investment. Yellow coloured diamonds are far more valuable than colourless diamonds and have appreciated in value over the last decade.

Even couples from the younger generation are opting for coloured diamonds in their engagement rings to feel unique and truly special. Advanced technology has allowed even faint fancy coloured diamonds being able to retain their colours even after the cutting process.

Infiniti Jewels: How It’s Evolved to a Multi-Million Dollar Diamonds Business

Bhavik Mehta shares his passion which sparked off from cutting diamonds to now selling $42,000 engagement rings

Bhavik Mehta founded Diastar Pte Ltd in 1982 which specialises in business-to-business dealings of diamonds. A passionate man who is a committee member of the Diamond Exchange of Singapore and who built his entire business single handedly, he is one of the top diamond grading experts in the country.

Vanilla Luxury: Share with us a little about your background.

BHAVIK MEHTA: I got into the diamond industry through a friend who was a big diamond manufacturer in Mumbai. While interning at the factory, I learnt how to cut diamonds and it excited me on how a raw stone converted into a sparkling gem after it is cut into facets.

I came to Singapore in 1981 from Mumbai to suss out the opportunities as I had family friends here which gave me the moral support versus moving to any other country. I started off in Diamond brokerage, selling to local jewellers, moving from one shop to another and earning a commission. Having built a good and supportive customer base, I knew I could grow further if I started my own company.

Vanilla Luxury: What sparked the launch of Infiniti Jewels?

BHAVIK MEHTA: 4 years ago when my sons joined the family business, Infiniti Jewels was started to cater to the consumer market for bespoke diamond jewellery. From USD$2,000 for a classic engagement ring to a $500,000 one-of-a-kind yellow diamond bracelet, there is something for everybody.

My sons are GIA Diamond Graduates while my daughter-in-laws are certified Jewellery Designers. They work together from the sourcing of diamonds to designing classic or exclusive and unique pieces for our customers.

Infiniti Jewels has grown rather fast in just a short period of time and our collections include engagement rings, wedding bands, necklaces, bracelets and a lot more.

Vanilla Luxury: What makes Infiniti Jewels different from other jewellers?

BHAVIK MEHTA: As Infiniti Jewels is an extension of Diastar to serve the consumer market, we are able to leverage on Diastar’s experience in the diamond trade as well our established network in the jewellery industry.

We aim to educate our customers on what diamonds to buy and what not to buy. It starts with them knowing about different diamonds and the 4Cs - carat, cut, colour and clarity - so that they can make an informed decision.

Infiniti Jewels is not only priced competitively, but also provides lifelong service to our customers such as cleaning and repairing of their jewellery.

Vanilla Luxury: Do you carry Coloured Diamonds?

BHAVIK MEHTA: Yes, we specialise in fancy yellow and fancy pink diamonds. Our diamonds are all natural, GIA certified and are sourced from conflict-free zones and suppliers.

Vanilla Luxury: Trends in Jewellery that you foresee in the next few years?

BHAVIK MEHTA: Consumers are starting to look for classic pieces which is good in a way as it never goes out of fashion. We also get a lot of requests to design evening wear pieces for cocktails, weddings and other lavish functions.

An interview with Bhavik Mehta, Founder of Family-Run Infiniti Jewels

PALACE speaks to Bhavik Mehta, one of Singapore’s top diamond-grading experts and the founder of family-run Infiniti Jewels, to find out more about the industry and what makes his custom jewellery design and manufacturing house unique.

From the vaults of royalty to the elegant visages of society’s rich and famous, there’s no denying the enduring appeal of diamonds. As the market for bespoke fine jewellery grows, these covetable rocks are the epitome of exquisite beauty and investment value.

An interview with Bhavik Mehta, Founder of Family-Run Infiniti Jewels

PALACE: Tell us a little bit about yourself, how did you grow your passion for the industry and what was the impetus behind Infiniti Jewels?

BHAVIK MEHTA: When I was a young man, I used to follow my brother to his diamond manufacturing factory to see how he was working. My passion came instantly through seeing the process of raw diamonds being cut and polished—from a diamond in the rough to a gorgeous sparkling beauty.

Our inspiration for Infiniti Jewels was to create a brand that produces high-quality jewellery with high-quality diamonds. We also wanted to offer a very bespoke experience for our clients – from diamond-selection education to the formation of inspiring designs.

What sets your brand apart from other jewellers in the local industry?

Our brand is very unique in that we have a very strong focus on a personalised experience for our clients. What I mean by that is how each customer experiences something different—from choosing the right stone together with our experts to selecting the right design in collaboration with our knowledgeable jewellery designers.

What kind of diamonds and precious stones do you work with and where do you source them from?

Infiniti Jewels specialises in coloured diamonds— something that is very rare and not easily accessible—such as pink, green, yellow, and orange. We also have a variety of unique designs rendered in white diamonds, rubies, emeralds and sapphires. These gems are sourced from a variety of different places and countries, depending on where we get the best quality and price. The majority of where we get our gems would be Belgium, Israel, and India.

The demand for bespoke luxury products is growing with more consumers today wanting something unique to exclusively call their own. From your experience, what is the most often-requested jewellery design from your clients?

When it comes to bespoke jewellery, everyone has different taste and most who want to make a bespoke piece usually go for a unique one-of-a-kind design so there is no most-often-requested design. But what is common is that most people usually request for a bespoke ring or earrings.

What are your thoughts on the current fine jewellery market? What future trends do you see emerging?

The current trend for fine jewellery is the preference for designs that involve more than one colour of diamond—so any combination of yellow, pink, white, green, and so on. Every customer has a different opinion of what is most valued, but what is increasing in price more than anything else is coloured diamonds, possibly due to the increase in demand and shortage of supply. I see this as a future trend as well, as more people are becoming aware of coloured diamonds and designs that involve these beautiful colours.

Take us through the process of customising a unique piece of jewellery with Infiniti. What can clients expect from such a collaboration?

When new customers visit us for the first time, we first educate them on diamonds by taking them through a sample certificate. We help them understand all the different variables that are important and that they should look out for. This will help them understand what kind of diamond would be best suited for them in terms of look and budget. For example, one of the most important aspects of a diamond to look out for is the cut.

One should always look for a stone with excellent cutting as that is what will really bring out the sparkle in a diamond. After that, we consult with them regarding the occasion they would like to create the piece for (if there is one). This helps our designers better understand what kind of aesthetic would fit the client’s requirements.

Next, we show the client some loose diamonds, and after the selection of the centre stone, our designers then get to work to come up with unique design options for the client, a process which can take a week. Base on this, you can see how this is a completely personalised experience.

Your thoughts on fine jewellery and/or diamonds as forms of investment?

Diamonds are certainly a robust form of investment, especially solitaires, which give a good and safe return in the long run. What gives a better investment (in my opinion) is coloured diamonds, as those are more rare and harder to source for.

What would you say has been your favourite / most memorable project to date and could you perhaps share with us a little more about it?

My most memorable project is when we were in the process of developing our brand for the Malaysian market. We participated in some jewellery shows, and I remember how our very first show went terrible for us. We made no sales and this was perhaps because we were a new brand that not many locals knew of.

I had told my two sons not to be disappointed and to keep trying, and I pushed them to participate in more shows with the confidence that we will do well. Today, our persistence have paid off for not only have we expanded our booths at trade shows, we also make it a point to travel to Malaysia every two weeks to meet with our clients and partners.

What would be your dream design project if you haven’t already achieved it?

My dream design project would be to create a masterpiece that can be worn in more than five ways. This would give the client a variety of different ways to wear one piece, making it look unique and value for money.

Is there anything in the pipeline for Infiniti Jewels that you would like our readers to know about?

All I can say is that there are exciting times ahead for our brand, which is currently collaborating with some of our exclusive partners in Singapore, Malaysia, Hong Kong, and Dubai for upcoming events that promise to be memorable for all. Besides also carrying an exclusive line of diamond jewellery in our store, we are currently in the works of creating some unique coloured diamond pieces so do stay tuned for more to come!

Expert Advice on Picking the Right Diamond this Valentine's

Diamonds are a woman’s best friend, but only the perfect diamond will last a lifetime. Purchasing the right diamond on Valentine’s for your partner usually is one of the happiest but most stressful moments at the same time. You are about to show how much you love, care, and appreciate the most wonderful person in your life - the woman you love. Why is choosing the right diamond so stressful? You have to put in mind and consider various aspects such as the cut, colour, clarity and carat.

Many individuals think that picking a diamond is easy, and that only one or two variables is important when choosing the perfect stone. We are quickly rounding up the most important variables to help you pick the perfect rock this Valentine’s Day. It’s all about balancing the 4C’s to what makes sense for you and your budget. So what are the 4C’s?


The most common mistake people make is that they think that a diamond’s cut simply refers to its shape, and not the sparkle that shines from the diamond. The cut determines the amount of light that enters through the top and reflects down and back up. The sparkle that shines from the diamond is one of the main differentiations between a diamond and a cubic zirconia. The cut grade is one variable that you should never compromise on.


The colour range, also known as the Normal Colour Range, for diamonds are based upon the alphabetical letters, starting with D. The color range is from D color, which is the most transparent (white), all the way down to Z (Light Yellow). The higher the color, the more rare the diamond is, which translates it to be more expensive in most cases. Many of the Jewelers keep commercial colors in their store that can be afforded by most buyers. Commercial colors fall from G to M color. If you are looking for a transparent color that fits within your budget, your best bet is going for an F color.


Clarity refers to the natural marks or inclusions inside a diamond. The most common inclusions in a diamond are - Feathers (these look like small cracks), Crystals (small crystaline inclusions inside the stone that occurred when the diamond was being formed) and Clouds (these are a group of very tiny inclusions that give a cloud-like appearance). Professionals use the clarity scale which ranges from FL (flawless), IF ( Internally Flawless), VVS1-VVS2 (very very slight inclusions), VS1-VS2 (very slight inclusions), SI1-SI2 (slight inclusions), and I1-I3 (Inclusions).


It is the weight and size of the diamond. Even though this is normally seen as one of the most important variables for a lady, it is in fact one of the least important variable when analyzing a diamond’s beauty. The higher the carat weight, the more rare the diamond is, which translates it to being more expensive.

Now that you've got a proffessionals perspective and guidance on the most important variables of a diamond. You are fully equipped in making the right choice. Just remember that when picking the perfect diamond, the carat weight is the least important factor that brings out the brilliance of a diamond. Quality should be the main focus, and you can achieve this by focusing on the perfect cut that is within your budget. Happy Shopping!
