Lab-Grown Diamond Loose

About our lab-grown diamond loose

Loose lab-grown diamonds, graded on the same 4C scale as natural stones and supplied with IGI reports where the value justifies the certificate. Composition is identical to natural diamond; provenance and resale are the differences that matter commercially.

Because these are sold stone by stone rather than by band, the listing carries the actual carat, colour and clarity rather than a category range. Confirm the report number before payment on anything above one carat.

Melee lab-grown is supplied with batch documentation rather than individual reports, which is normal at that size and keeps the per-stone cost viable.

What buyers usually ask before the first order

The patterns below come from repeat purchase data, not from a marketing brief. If your assortment differs, say so in the enquiry and we will quote against your spec instead of ours.

Stone and metal combinations

Most of this category is produced in 925 sterling silver with rhodium plating, because that keeps the landed cost low enough to test a new design. Once a style proves itself, the same CAD file is re-cast in 10K, 14K or 18K gold — no new tooling, no new mould cost.

Sizing and finishing

Rings are made to US, UK or EU sizes on request; bracelets and chains ship at 16–20 inches unless a length is specified. Plating thickness is recorded per batch, which matters if your market tests for nickel release.

Reorder behaviour

SKUs are permanent. A reorder of the same SKU in a later season uses the original CAD and the original stone sourcing, so the second delivery matches the first.

Price band for this category

Current factory listings sit between $180 and $2,200 per piece. The range reflects stone size, metal choice and setting labour — a 0.5 ct silver solitaire and a 3 ct gold three-stone sit at opposite ends of the same category.
