Ordering and accounts
Who can buy from Liora Diamond?
Businesses only: retail jewellers, wholesalers and dealers, jewelry manufacturers, online brands and private-label designers. We do not sell to consumers.
What is the minimum order?
US$2,000 per order. We don't accept enquiries for single items under that amount.
How do I place a first order?
Send a spec by form or WhatsApp. We reply with a shortlist, photos, video, reports and trade prices. You confirm, we issue a pro-forma invoice, you pay by bank transfer, and we ship insured.
Do you offer credit or memo?
First orders are prepaid. Memo and payment terms can be discussed with established accounts after a history of paid orders.
Which currency do you quote in?
U.S. dollars, the standard currency of the diamond trade. We can give indications in other currencies for budgeting.
Can you hold a stone while I check with my customer?
Short holds on stock stones are usually possible. Tell us how long you need when you ask.
Grading and quality
Which labs grade your diamonds?
Larger stones are normally supplied with IGI reports. GIA and other lab reports can be arranged on request. Report numbers verify on the lab's website.
What is the difference between CVD and HPHT?
Both are ways of growing real diamond. CVD builds the crystal layer by layer from a carbon-rich gas; HPHT recreates the high pressure and temperature of the earth. The finished stones are chemically identical to mined diamonds. The report states the method.
Are lab-grown diamonds treated?
Many CVD stones receive a post-growth treatment to improve colour, and many fancy colours are produced or enhanced after growth. Grading reports disclose this, and so do we.
What does eye clean mean?
No inclusions visible to the naked eye face-up at a normal viewing distance. VS2 and better is almost always eye clean; SI1 often is, judged stone by stone.
Can I see a stone before paying?
Yes. We send photos and 360° video of the exact stone, and can film under different lighting or next to a ruler on request.
Big and fancy colour diamonds
What sizes do you supply?
From melee up to statement stones of 20–30 ct, in singles and matched pairs.
Which fancy colours are available?
Pink, yellow, blue and green in most sizes, from Fancy Light to Fancy Vivid, plus brown, black, purple, orange and red in smaller quantities.
Can you match colour across a parcel?
Yes. We match fancy colour parcels for hue and intensity, and film the parcel together so you can judge consistency.
B2B jewelry
Can you produce jewelry under our brand?
Yes. We make pieces to your CAD or ours, stamp them with your mark and pack them to your instructions.
What metals do you work in?
10K, 14K and 18K gold in white, yellow and rose, platinum, and silver for fashion lines.
