CORE DIAMONDMELEE

Sourcing & provenance

Custom sourcing

Standard inventory covers 90% of bench needs. For everything else — fancy shapes, natural melee, matched suites — we source to spec.

What we source

  • Natural melee in commercial qualities (G-H, SI) and white qualities (D-E, VVS-VS).
  • Fancy color CVD — yellow, pink, blue — calibrated and matched.
  • Fancy shapes outside our standing line: hexagons, kites, shields, baguettes to length spec.
  • Matched suites for layouts (cluster halos, pavé eternity bands, side-stone trios).

Provenance

Natural stones source under the Kimberley Process and the Responsible Jewellery Council's Chain of Custody. Lab-grown stones are labeled by growth method (CVD or HPHT) and reactor batch is logged at receiving — never co-mingled with natural inventory.
