Uncertified and heirloom diamonds welcome
Many shops refuse or heavily discount diamonds with no certificate, no receipt, or an inherited history. Our gemologists test, grade and buy undocumented stones at fair international market rates.

What usually goes unpriced
Many conventional buyers value a ring by the weight of its gold alone. The diamond, the gemstones and the craftsmanship are written down to nothing or quoted at melt value — and that is exactly where most of your value sits.
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
- Diamonds disregarded, with only the gold weight paid for
- Buyback deductions of 10–25%, and steeper still without the original receipt
- The piece taken to a back room to be “checked”, out of your sight
- Leaving with a large amount of cash after the sale feels exposed
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
- Funds wired straight to your bank account in SGD or USD
- A licensed Singapore company with an address and a public record
Extra 10% for jewellery we can resell
For jewellery we can resell and feel is suitable for us, we will pay 10% over the gold price.
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.
100% transparent, in your sight
Your jewellery never goes into a back room. Weighing, gold assay and stone grading all happen at the same table, and we explain each figure as we go.
Secure, private, cash-free
A one-to-one consultation in a closed room, by appointment. Payment goes straight to your chosen bank account — you never walk out carrying cash.

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 a direct bank transfer 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.

Private VIP consultations in Indonesia
While most clients visit our Singapore office, for high-value collections or large-carat diamonds, our senior gemologists also travel directly to Jakarta and major Indonesian cities for private, secure VIP consultations and transactions by prior arrangement.
Arrange a VIP consultation on WhatsAppWhich certificates we accept
We price the stone, not the paperwork. A missing certificate — or a question mark over a laboratory — 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
- GRI, SkyLab, AGL, MGL, BIG Lab, GLI and other local laboratory memos
- Shop receipts or purchase notes, including from retailers now closed
- Family heirlooms with no documented history 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 — a safe place to close the deal
Personal safety and discretion are the main reasons our clients choose to complete the transaction here rather than close to home.
A private room, by appointment only
No open counter, no queue, nobody else in the room. Just you and the valuer.
No cash to carry
Once the price is agreed, funds go directly to your bank account. You leave the office carrying nothing that draws attention.
Your privacy and reputation 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 legal and financial system
The transaction takes place inside a tightly regulated financial centre, with payment documented through Singapore's banking system.
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 loose 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 are visiting Singapore for business, a holiday, or a medical appointment
- 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.
