Real money, not trade-in credit
You do not have to buy something else to unlock the value of your jewellery. We buy outright, and you leave with funds rather than a voucher.

Trade-in credit is not the same as real value
Most local retailers offer trade-in credit rather than cash — and when cash is offered, it is often calculated on second-hand gold weight alone. The diamond and the craftsmanship are treated as worth nothing.
We price each component separately and show you the arithmetic: the metal weighed at the day's gold rate, and the stone graded against live international market indexes.
What sellers commonly run into at home
- Trade-in credit offered instead of cash you can actually use
- Pricing based on second-hand gold weight, with the diamond unvalued
- Heavy deductions when the original receipt or purchase certificate is missing
- A close-knit community — you want this to stay private
What you get in Singapore
- Diamonds and gemstones valued in full, separately from the metal
- Every test performed at the same table, in front of you
- Cash or direct transfer to your bank account in SGD
- For jewellery we can resell and that meets our criteria, we pay 10% above the gold price
- A licensed Singapore company with an address and a public record
Why sell with us in Singapore
We are a direct buyer, not a consignment desk. You are not waiting for a buyer — you are getting paid.
Full value for the stones
We grade cut, clarity, colour and carat against global market indexes, then price the gold separately at the day's rate. Two numbers, both shown to you.
Uncertified diamonds welcome
Heirloom pieces, uncertified stones, or items with no receipt — our gemologists still test, grade and quote at fair international market rates.
Discreet and secure
A one-to-one consultation in a closed room, by appointment. No open counter, nobody else in the room, and nothing recorded publicly.
GIA / IGI recognized
Private consultation room
Direct bank transfer
Three simple steps

Send photos on WhatsApp
Send photos of your jewellery or diamond and any certificate, via WhatsApp or the form below. Include carat, shape and report number if you know them.
- 02
Get an estimate before you travel
Within 24 business hours we reply with a range grounded in international market levels — before you plan the trip. If the number does not justify it, we will say so plainly.

Meet at Kreta Ayer and get paid
A fixed appointment at 29A Kreta Ayer Road, Singapore. The meeting usually takes 30–60 minutes: inspection in front of you, price agreed, then payment on the spot.
Bring your passport, the item, and any certificate or receipt. Remote estimates are non-binding; the final number is confirmed after physical inspection. If you disagree, you take your item home at no cost.

Which certificates we accept
We price the stone, not the paperwork. A missing certificate does not cost you the sale.
International reports
- GIA — Gemological Institute of America
- IGI — International Gemological Institute
- HRD Antwerp
- Other recognised international laboratories
Local memos and no paperwork at all
- AGL, MGL and other Malaysian gemmological laboratory memos
- Shop receipts or purchase certificates, including from retailers now closed
- Family heirlooms with no documentation whatsoever
- No receipt, no certificate — we still test and quote
Laboratory-grade verification on site
At our Singapore office your stone is weighed on a calibrated scale, examined under a gemmological microscope and tested with instruments held to international laboratory standards — all in front of you. The measured result sets the number, not the paper that came with it.
Singapore — close by, regulated and safe
From Johor Bahru it is a short trip; from Kuala Lumpur or Penang, a short flight. For many of our clients this is settled within a single day.
Easy to reach from anywhere in Malaysia
Our Kreta Ayer office sits beside public transport, suited to a day trip from JB or a morning flight from KL.
A private room, by appointment only
No open counter, no queue, nobody else in the room. Just you and the valuer.
Your privacy protected
We take no photographs, publish no names and share your details with nobody. Your decision to sell stays entirely your own business.
A stable financial system
The transaction takes place inside a tightly regulated financial centre, with payment documented through Singapore's banking system in SGD.
Who this is for
We would rather be straightforward from the start, so you spend neither time nor travel money unnecessarily.
A good fit if
- You hold a diamond or jewellery of significant value (typically from around 1 carat, or several pieces combined)
- You have a GIA / IGI report — or none at all, we will still look
- You can come to Singapore for work, a holiday or a day trip
- You want a real number and a clean decision
Not yet a fit if
- The item is modest in value — travel would consume your proceeds
- You expect to recover the original retail price you paid
- You only want an appraisal to keep, with no intention of selling
What decides your number
There is no secret formula. These are the factors we assess, and we will point to each one on your own stone.
- Carat and shape
- Actual weight on the scale, plus current demand for that cut.
- Colour and clarity
- Grade and inclusions checked under the microscope against the report.
- Cut quality
- Proportions and finish materially change resale demand.
- Certification
- GIA / IGI supports a stronger price. Local memos are re-verified independently.
- Wholesale spread
- The gap between the retail price you paid and today's wholesale level — this is where most value was lost.
- Gold and side stones
- Metal is weighed separately at the day's gold price; melee is priced on its own.

Frequently asked questions
Because diamonds are valued in full against international market indexes rather than second-hand gold weight, because we pay cash or bank transfer rather than trade-in credit, and because the trip is short — many clients settle it within a single day.
No. We buy outright. You never have to purchase anything from us to receive the value of your jewellery.
Yes. Much of what is brought to us has no paperwork. Our gemologists test and grade the cut, clarity, colour and carat in front of you using laboratory instruments.
No. We value the item, not its purchase history. A missing receipt does not reduce the physical value of your diamond or gold.
We see clients by appointment only, in a closed room, with no open counter and nobody else present. We take no photographs, publish no names and share your details with nobody.
Once the price is agreed, payment is made in cash or by direct transfer to your chosen bank account in SGD, the same day.
Never. All weighing, testing and stone grading happen at the same table, in front of you, from start to finish.
Against live international wholesale indexes for your specific grade, less handling costs, plus the gold at the day's rate. We explain the calculation at the table.
Yes. We buy gold jewellery, luxury watches and other gemstones. Gold is weighed and priced at the day's market rate.
You take your item home at no cost. No appraisal fee, no obligation, no pressure.
Personal jewellery may be carried in for a valuation appointment. Bring any documents you have and declare the items if asked at the checkpoint. The inspection itself costs nothing.
No. A local appraisal is not required and does not affect our price. We grade the item ourselves, in front of you, with laboratory instruments.
Payment is made in SGD, in cash or by bank transfer on the same day. You are free to convert it to ringgit or transfer it to your Malaysian account.
