Lab-Grown Diamond Melee for Jewelers — DE VS-VVS, by the 1-ct Bag, Duties Prepaid

How it is sold

Round melee — by the 1-carat bag, one size per bag

You choose a size such as 1.5 mm; the bag holds 1 carat of stones sorted to within ±0.1 mm of it, roughly 65 pieces at that size. The millimetre size is the specification. From 3 mm up, where each stone weighs 0.10 ct or more, a bag is made up as close to 1 carat as whole stones allow and can run slightly over or under. Mixed bags and tighter sorting are available on request.

Single stones — by weight band

Eight bands of 0.1 ct from 0.19 to 0.99 ct, one fixed price each. The exact weight is written on the packet. Matched pairs on request.

Fancy shapes — by the 1-carat bag, two price tiers

Stones of 0.04 ct and up per stone are one price; under 0.04 ct, another. Each product page has a guide to which tier a given millimetre size falls in. Because fancy melee comes in many length × width combinations and not all are in stock at once, send the mm you need first and we confirm with a photo before you pay.

Grading

• Colour DE, clarity VS–VVS. Melee is sorted and graded as a parcel to the supplier's standard, as it is throughout the trade; it is not graded stone by stone.
• Rounds are Hearts & Arrows cut. Face-up symmetry you can check under an H&A viewer.
• No grading report is included with melee or with single stones under 1 ct. Stones of 1 ct and above are quoted from stock and can be supplied with a report; ask when you enquire.
• Wording. Everything here is described as laboratory-grown diamond, with the qualifier next to the word diamond, as the FTC Jewelry Guides and ISO 18323 require. We recommend the same wording on your invoices.

Compared with mined diamond

Laboratory-grown diamond is diamond: the same carbon crystal, hardness 10, the same brightness and fire, the same reading on a thermal tester, and the same rules at the bench. It sits unnoticed next to a mined centre stone, which is the usual use for it. The differences are origin, price, what a screening instrument reports, and the wording on your invoice — laboratory-grown diamond, never diamond alone.

Questions jewelers ask

Will the stones pass a diamond tester?

Yes. Thermal and electrical testers read laboratory-grown diamond as diamond, because it is diamond. Instruments built to separate natural from laboratory-grown will flag them as laboratory-grown, which is correct.

Is there a minimum order?

One 1-carat bag, or one single stone. Larger quantities ship at the same listed price; ask if you need more than we show in stock.

Can I get tighter sorting than ±0.1 mm?

Usually, yes — tell us the tolerance you need and we sort to it or tell you what is possible.

Can I set it next to a mined centre stone?

Yes — that is what most of it is bought for. It matches a mined stone in colour, brightness and tester response; disclose it on the invoice and appraisal as laboratory-grown diamond melee.

Do you sell to the public?

Anyone can buy at the listed price. The products are written for jewelers because that is who buys loose melee.
