Lab-grown diamond jewellery, made to be yours.
A bespoke atelier in Far East Plaza, built on twenty-four years in the international diamond trade. Every piece is designed with you, cut to your stone and finished by hand.
We are not a shop. We are the workshop.
Venlis is a direct manufacturer, which means the person who advises you on a stone is the same house that sets it. There is no distributor between your idea and the bench, so a change of shape, carat, clarity or metal is a conversation rather than a special order.
We work two ways. Bring a design, a photograph or a rough sketch and we will draw it up properly. Or bring nothing at all, sit down with loose stones, and we will design it together from the first prong.
Every piece here can be remade as yours.
These are pieces we have made. Each one can be rebuilt to a different stone shape, carat, clarity, metal or setting, because we are the manufacturer. Select any piece to begin a conversation about your version of it.
The same stone. A different origin.
A lab-grown diamond is a diamond. Same carbon lattice, same hardness, same refraction, same fire. What differs is where it formed, and what that costs.
Are lab-grown diamonds real diamonds?
Yes. They are chemically, physically and optically identical to mined diamonds. A gemmologist cannot tell them apart by eye or with a loupe. Distinguishing them requires specialist equipment that reads the growth pattern, which is why reputable stones are laser-inscribed and certificated.
How are they graded?
On the same four criteria as any diamond: carat, cut, colour and clarity. Our stones are IGI certified, so the grading is issued by an independent laboratory rather than by us.
Will anyone be able to tell?
Not by looking. A well-cut lab-grown stone of good colour and clarity outperforms a poorly cut mined stone of the same weight, every time. Cut quality is what the eye actually reads as brilliance.
What is the honest trade-off?
Resale. The secondary market for lab-grown diamonds is young and prices have moved as production scaled. If you are buying to wear, that is immaterial. If you are buying as a store of value, we will tell you plainly that a mined stone is the better instrument, and we trade those too.
Founded by Vicky Ji.
Her career began in 2002 at Royal Coster Diamonds in Amsterdam, one of the oldest diamond houses in Europe. She remains an active force in international natural diamond wholesaling to this day.
Born in Beijing, raised in Europe, and in Singapore for more than a decade, she founded Venlis in 2010 and went on to build an international bridal business spanning Singapore, Bali and the Maldives. That work drew a feature on Hunan TV and an invitation from the President of Palau to advise on luxury tourism.
Today Venlis brings both worlds together: a traditional natural diamond supply chain, and a flagship lab-grown atelier in Far East Plaza.
"I purchased a lab-grown diamond ring for my anniversary, and my partner was speechless. The brilliance and clarity are amazing."
Venlis client"I was skeptical about lab-grown diamonds at first, but this piece exceeded every expectation. The craftsmanship feels luxurious."
Venlis client"The craftsmanship is excellent, the stone shines beautifully in every light, and it arrived exactly as described."
Venlis clientSit down with the stones before you decide anything.
A consultation is an hour at our Far East Plaza showroom with loose diamonds on the tray in front of you. No obligation, and no pricing conversation until you have seen what you are actually choosing between.
Book a Consultation →Your design, drawn properly and built by hand.
Seven steps from the first sketch to the finished piece, with a 2D rendering to approve before anything is cut.
Custom-made fine jewellery, and the services around it.
Over twenty years in the jewellery industry, working as a direct manufacturer rather than a reseller. That is what lets us quote a change rather than refuse it.
Lab-grown diamond jewellery
Rings, earrings, bracelets and necklaces built around IGI-certified lab-grown stones in the shape, carat and clarity you choose.
Custom-made designs
From your sketch, a photograph, a piece you already own, or from nothing but a conversation at the bench.
IGI certified diamonds
Independent laboratory grading on the stones we supply, so the specification you are told is the specification you can verify.
Gemstones and fine jewellery
Coloured stones alongside diamonds, including fancy yellows and pastel blues, set to the same standard.
Jewellery repair and resizing
Including pieces that were not made by us. Bring in what needs attention.
Direct manufacturer
No distributor markup between the bench and you, which is the reason a bespoke commission here is not automatically the expensive option.
Seven steps, and you approve the drawing before we cut.
Share your design
A sketch, a screenshot, a piece you already wear, or simply the occasion it is for. We start from whatever you have.
Invoice and deposit
A deposit secures the stone and opens the commission. We show you this step openly because a bespoke piece cannot begin without it.
2D rendering
We draw your piece properly, to scale, so you are approving a design rather than imagining one.
Review and confirmation
You see the rendering and tell us what is not yet right.
Revision and adjustment
Proportion, prong height, band width, stone placement. This is the stage where a piece stops being close and becomes correct.
Final design and production
Once you sign off the drawing, the piece goes to the bench and is made.
Delivery in 10 to 14 days
From confirmed design to finished piece in your hand.
Bring an idea. Or bring nothing.
Most of our commissions start with a conversation rather than a drawing. Book an hour, see the stones, and we will design from there.

The ring is the easy part. The stone is the decision.
Bespoke lab-grown diamond engagement rings, designed with you at our Far East Plaza atelier.
What actually matters, in order.
Most people arrive worrying about carat. Carat is the fourth most important thing in the room.
Cut, first and by a distance
Cut is the only one of the four that is a human decision rather than an accident of formation, and it is the one the eye reads as brilliance. A superbly cut stone of modest weight outshines a heavy, badly cut one under any light.
Shape, because she has to wear it
Round brilliant, oval, pear, emerald, cushion, marquise, heart, asscher. Shape changes how a stone reads on the hand far more than half a carat does.
Colour, to the point of diminishing return
Above a certain grade you are paying for a certificate rather than a visible difference, particularly once the stone is set in yellow or rose gold.
Carat, last
Decided by what is left, not by what is first. We will tell you where the weight stops being visible.
Solitaire, halo, three stone, bezel, eternity.
A selection of ring settings we have built. Each can be remade around your stone.
Come in before you decide anything.
An hour with loose stones on the tray tells you more than a month of browsing. Bring her ring size if you have it, and bring nothing else.
Book a Consultation →
A diamond, grown rather than dug.
What a lab-grown diamond is, how it is graded, and the one trade-off that nobody in this industry likes to mention.
It is carbon, arranged the same way.
A mined diamond formed under pressure in the earth. A lab-grown diamond formed under pressure in a reactor. The resulting crystal is the same material with the same hardness, the same refractive index and the same fire.
The distinction is origin, not substance. That is why the trade calls them lab-grown rather than synthetic or simulated. A cubic zirconia is a simulant, a different material pretending to be a diamond. A lab-grown diamond is not pretending to be anything.
How are they actually made?
Two methods dominate. High pressure high temperature recreates the conditions of natural formation. Chemical vapour deposition grows the crystal layer by layer from a carbon-rich gas onto a diamond seed. Both produce genuine diamond.
Can a jeweller tell the difference?
Not with a loupe, and not by eye. Identification requires laboratory instruments that read growth structure and trace elements. This is exactly why certification matters: the certificate, not the appearance, is what tells you what you own.
What does IGI certification cover?
The International Gemological Institute grades the stone independently on carat, cut, colour and clarity, and records its origin. The report is issued by the laboratory, not by the seller, which is the entire point of it.
Are they more ethical?
They avoid the supply-chain questions that surround mining, which many of our clients care about. They are not free of impact: growing diamond is energy intensive, and the honest position is that the footprint depends on how that energy was generated.
What about resale value?
This is the trade-off. Lab-grown production has scaled fast and prices have fallen with it, so the secondary market is weak and unpredictable. If you are buying something to wear and pass on, this does not matter. If you are buying a store of value, a mined stone is the better instrument, and we will say so, because we trade those as well.
Why buy from an atelier rather than online?
Because a certificate tells you the grade and nothing about how the stone looks on a hand in daylight. Two stones with identical paperwork can perform very differently. Seeing them side by side is the part that cannot be done through a screen.
Two stones, one tray, daylight.
We will put a lab-grown stone next to a mined one of the same specification and let you decide what you can actually see. Most people find the conversation settles itself in about ten seconds.

Buy the stone first. Design around it.
IGI-certified loose lab-grown diamonds and coloured gemstones, supplied to private clients and to the trade.
Select the stone in person, then commission the setting.
The most satisfying commissions we build start with a client choosing a specific stone on the tray rather than a specification on a page. Shape, cut quality and the way a stone behaves in daylight are not things a certificate communicates.
We hold round brilliants, ovals, pears, emerald cuts, cushions, marquises, hearts and asschers, alongside fancy yellows and pastel coloured stones. Anything we do not have, we source through the same supply chain we have used for two decades.
A B2B supply line, not a retail counter.
Venlis operates a wholesale network alongside the retail atelier. Our founder has been active in international natural diamond wholesaling since 2002 and continues to be.
Retailers, designers and independent jewellers can source certified lab-grown and natural stones through us directly. Enquiries from the trade go to the same address as everything else, and we will route them properly.
Stones are shown by appointment only.
Loose stones are not kept on open display. Book a viewing and we will have the shapes and grades you are considering on the tray when you arrive.
Book a Consultation →Twenty-four years, Amsterdam to Scotts Road.
Venlis was founded by Vicky Ji in 2010. Her diamond career began eight years before that, in one of the oldest diamond houses in Europe.
Vicky Ji
Her career is rooted in the heritage of fine jewellery, beginning in 2002 at Amsterdam's historic Royal Coster Diamonds. She was born in Beijing, spent her formative years growing up in Europe, and has been in Singapore for more than a decade.
Cultivating a lifetime of mastery in the natural diamond trade, she has remained a trusted and active force in international natural diamond wholesaling to this day. That is unusual. Most people who sell lab-grown diamonds arrived with the category. She arrived twenty years before it.
As a luxury entrepreneur she paired that diamond expertise with the world of high romance, building an international bridal business spanning Singapore, Bali and the Maldives, working with elite clients, influencers and celebrities. The work earned a feature on Hunan TV and a personal invitation from the President of Palau to advise on luxury tourism initiatives.
Venlis is where both halves meet: a deep, ongoing mastery of the traditional natural diamond industry, joined to the innovation of premium lab-grown stones, supported by a global supply chain that serves both a B2B wholesale network and an exclusive retail presence.

What we would tell you at the bench.
Guides to choosing, wearing and caring for diamond jewellery, written by the people who set the stones.
Written to be useful, not to rank.
Which, as it happens, is also how you rank. Each guide below answers a question we are genuinely asked across the counter.
How to choose a diamond shape for the hand that will wear it
Finger length, knuckle width and how the wearer actually uses their hands all change which shape reads well. An elongated oval or marquise lengthens a shorter finger. An emerald cut suits someone who wants presence without sparkle. Six minutes.
Cut quality: the only grade you can see across a room
Why two stones with the same carat, colour and clarity can look nothing alike, and what to look at on a certificate before you look at anything else. Eight minutes.
Lab-grown against mined: an honest side by side
Written by a house that sells both, including the resale question that most retailers skip. Nine minutes.
Caring for pavé settings in Singapore humidity
What tropical humidity, sunscreen and hand sanitiser actually do to a pavé setting, and how often a piece genuinely needs checking. Five minutes.
What to bring to a bespoke consultation
A short, practical list. The single most useful thing is a photograph of something you dislike. Four minutes.
Ring sizing without spoiling the surprise
Four methods that work, one that does not, and what we can adjust afterwards. Five minutes.
A question we have not written up yet?
Bring it to a consultation. The answers here started as questions somebody asked across the counter.

In the building, not on the street.
Our flagship showroom sits on level four of Far East Plaza, alongside the district's luxury watch dealers. It is a short walk from Orchard Road and from Newton.
Walk-ins are welcome, but loose stones are brought out by appointment, so booking first is the difference between a look around and a proper consultation.

We are easier to find than to describe.
Book a time and we will have the tray ready. If you are already in the building, WhatsApp us and we will tell you which lift to take.
Book a Consultation →An hour, a tray of stones, no obligation.
Private appointments at our Far East Plaza showroom.
You will not be sold anything in the first hour.
A consultation is a working session. We put loose stones on the tray, talk about what the piece is for, and sketch. If you leave without commissioning anything, that is a normal outcome and an entirely acceptable one.
Bring whatever you have
A photograph, a screenshot, a ring you already own, or nothing.
See stones side by side
Including a mined stone next to a lab-grown one of the same specification, if you want the comparison.
Leave with a direction
Not a contract. A clear idea of shape, setting and what it will take.
