CVD diamond price per carat in Thailand — updated monthly

CVD diamond price per carat in Thailand — updated monthly

Most suppliers won't publish prices. We do, because hiding the numbers wastes everyone's time. The table below shows current Bangkok wholesale ranges for IGI certified CVD diamonds. Prices move with the market, so we update this table every month. And if you want exact quotes on specific stones, send us your spec and we'll reply the same day with what's on the desk right now.

Two things a price table can't show you. First, cut quality. A poorly cut stone at a great per carat price is still a poorly cut stone, and we don't stock them. Second, tinge. Some CVD material carries a faint brown or grey cast that certificates don't fully capture. Every stone we quote has been checked by eye, under daylight lighting, before the price goes on it. That's the difference between buying from a trading desk in Bangkok and buying blind off a platform.

Lab grown Diamond wholesale in Bangkok, direct from Lab Grown Dreams

Bangkok has been a global cutting and trading hub for generations, and the lab grown trade runs through the same few blocks of Silom. Our office is inside the Jewelry Trade Center, which means when you buy from us you're buying at the source, not through a broker adding a margin between you and the goods.

Wholesale with us works the way the trade should work:

  • Volume pricing that's actually tiered. A fifty carat order prices differently from a five carat order. Tell us your projected volumes and we'll quote accordingly.

  • Sourcing to spec. If we don't have your exact size, shape, or quality in stock, give us two days. Our grower and cutter relationships go deep.

  • Export handled. Invoicing, shipping, insurance, and Thai export paperwork all done in-house. Goods leave Bangkok fully documented.

  • Payment by bank transfer. Standard for export orders. Established buyers can discuss terms.

And if you're in Bangkok, come to the office. Sit down, loupe the goods under proper light, drink the coffee. The best wholesale relationships in this city still start face to face.

IGI-Certified Lab grown diamonds in Thailand

Every center stone we sell above 0.50 carats carries an IGI report. IGI is the standard the global trade prices lab grown diamonds against, and every report is verifiable on IGI's website in seconds using the report number laser-inscribed on the stone's girdle.

What the report confirms: the four Cs, that the stone is lab grown, the growth method (CVD or HPHT), and whether any post-growth treatment was applied. We disclose post-growth HPHT treatment before you ask, because you should never have to ask.

One honest note on certification. Melee and small calibrated goods are not certified — nobody in the trade certifies a 1.5mm stone, the economics make no sense. For melee, your supplier's grading honesty is the certificate. Which is exactly why consistency across reorders matters more than any single parcel, and it's the thing our manufacturing clients stay for.

Loose Lab Grown Diamonds in Bangkok — How to judge a supplier

Whether you are buying a natural diamond or a CVD judge every diamond supplier in any country on the same five things:

  1. Lighting. Goods should be shown under daylight-equivalent lighting, not warm spotlights that flatter everything.

  2. The loupe test. A real supplier hands you the loupe and steps back.

  3. Tinge disclosure. Ask which stones carry brown or grey nuance. Watch how directly they answer.

  4. Depth behind the desk. Ask for something they don't have in stock. A supplier with real relationships says "give me two days." A trader with no depth goes quiet.

  5. Treatment disclosure. Post-growth HPHT treatment is legitimate and stable, but it should be volunteered, not extracted.

We put this list on our own page because we pass it. Come test us on it.
