Buyer's notes
Short answers to the questions that decide what you buy.
CVD or HPHT?
Both produce real diamonds, chemically identical to mined ones. CVD dominates larger white and many fancy colour stones; HPHT is common in melee and some colours. The report states which method was used.
IGI or GIA?
IGI grades most lab-grown diamonds in the trade and turns reports around quickly. GIA reports carry weight with some retail customers. We supply both and can grade to your preferred lab on request.
What "eye clean" means
No inclusions visible to the naked eye face-up at normal viewing distance. VS2 is almost always eye clean; SI1 often is, stone by stone. We confirm it on video for shortlisted goods.
Questions trade buyers ask

Who does Liora Diamond sell to?
Businesses only: retail jewellers, wholesalers and dealers, jewelry manufacturers, online jewelry brands and private-label designers. We do not sell to consumers, and we don't accept enquiries for single items under US$2,000.
What is your minimum order?
US$2,000 per order. Above that there is no fixed minimum quantity — one big stone or a parcel of melee both qualify, as long as the order is for a business.
Are your lab-grown diamonds certified?
Larger stones are supplied with IGI grading reports, and GIA or other lab reports can be arranged on request. Ungraded stones and melee are sold to an agreed specification, and we can send any stone for grading before shipment. Every report can be verified on the lab's own website.
Do you grow the diamonds by CVD or HPHT?
Our stock is mostly CVD, with HPHT on selected sizes. The growth method is stated on the grading report and on our invoice, and you can ask for either.
How big can the stones be?
We supply from melee up to statement stones of 20–30 ct. Stones from 3 ct upward are covered on our Big Diamonds page, including matched pairs.
Do you supply fancy colour lab-grown diamonds?
Yes. Pink, yellow, blue and green are available in most sizes, from Fancy Light to Fancy Vivid, with rarer hues on request. Singles, pairs and matched parcels.
Can you make jewelry under our brand?
Yes. We make tennis bracelets, eternity bands, semi-mounts, studs, pendants and one-off pieces to your CAD or ours, in 10K–18K gold and platinum, stamped and packed to your instructions.
How quickly do you reply to an enquiry?
Within one business day by email, and usually much faster on WhatsApp. Shortlists include photos, videos and grading reports so you can decide without seeing the stones in person.
Which countries do you ship to?
We ship worldwide by insured valuables courier, with a commercial invoice, packing list and original grading reports. Our market pages cover the U.S., Canada, the U.K., the UAE, Australia, Europe, Israel, Hong Kong, Singapore and Japan.
How do we pay?
By bank transfer against a pro-forma invoice. Terms for repeat trade accounts are agreed individually after the first orders.
