Short answer
A practical guide for jewelry factories and watch/fashion buyers sourcing sieve-sorted lab-grown melee parcels.
Melee buying is about parcel consistency
For production buyers, the question is whether the parcel works at the bench. Size band, color spread, clarity range, and packing method matter more than a single headline price.
RFQ details that reduce back-and-forth
Send millimeter size, sieve tolerance, color range, clarity range, parcel weight, use case, destination, and whether the parcel is for repeat production.
Repeat orders need a target file
Keeping accepted size tolerance, color spread, clarity range, and packing notes makes repeat melee orders faster and easier to compare.
