Lab Diamond Sourcing

Matched Lab-Grown Diamond Pairs & Melee for Jewelry Production

Define the visual and measurable matching criteria before sourcing. Matched pairs and melee need different specifications and should not be treated as the same purchasing unit.

For professional jewelry buyers

Specifications, pricing, minimums and timing are confirmed for every quotation.

Matched pairs

Pairs are reviewed for shape, dimensions, weight, color, clarity and visual consistency. The acceptable tolerance depends on the jewelry design and must be stated in the request.

Measured match

Dimensions and weights appropriate for the intended pair.

Grading match

Requested color and clarity relationship.

Visual match

Outline, facet pattern and face-up appearance when media is available.

Melee

Melee requests should state millimeter size or range, quality range, count or total carat weight, growth-method preference and intended use. We do not claim that every small stone carries an individual IGI report.
