Why buy a diamond from a Bangkok gem house?
Because we buy stones for a living. We have an established diamond supply line here in Bangkok, so we judge real stones against your brief, not a list of numbers on a screen.
-
You see the actual stone
Two diamonds with the same grades can look quite different. We send video of the stone itself in daylight before you commit.
-
A gemologist checks it
Our stones are assessed in-house by a GIA Graduate Gemologist, and we explain what the report does and doesn't tell you.
-
Honest advice on budget
Tell us your budget and we'll tell you where it's worth spending, and where you wouldn't see the difference.

My family has been in Bangkok's gem trade since 1963. A diamond is a big purchase, and most people only make it a few times. So ask us anything and take your time. If a stone isn't right for you, we'll say so.Anu, Thai Gems
Questions people ask
How much will it cost?
It depends on the stone and the design. Tell us your budget and we'll show you what it can buy. You get a clear quote in writing before anything is ordered.
Are your diamonds natural?
Yes. We deal in natural, earth-mined diamonds only. We don't sell lab-grown.
Will my diamond come with a report?
You can choose a GIA or HRD certified diamond, from 1 carat to over 10 carats, or a non-certified diamond. If it has a report, you'll see it before you decide.
Can I see the diamond before I buy?
Yes. We send video of the actual stone. If you're in Bangkok, you can also view it by appointment at our office in Gems Tower.
How long does it take?
It depends on the stone and how complex the piece is. Ready stock is quicker. We give you a timeline before you commit, so tell us if you have a date in mind.
Can you copy a design I've seen?
Send us a photo, a sketch or a link and we'll tell you what's possible. We can also adapt it to your stone and budget.
Do you ship outside Thailand?
Yes, we ship worldwide by insured, tracked courier. Import duty and taxes in your country are paid by you.
Can I return a custom piece?
Custom and personalised orders can't be returned, which is why you approve the stone and the design first.
How do I pay?
By credit or debit card, PayPal or bank transfer. We agree the price and payment steps in writing before work starts.
Tell us what you have in mind
A rough idea is enough to start. WhatsApp is the quickest way to reach us, and we can send photos and video of the actual stone there.
