Consistency across the parcel

Specify the diameter tolerance, colour and clarity range, total weight or approximate count, and your intended setting. Matching is particularly important when stones sit side by side.

Documentation and pricing

Small melee is normally supplied with parcel specifications rather than individual grading reports. Confirm the available screening and documentation for your order. We quote per carat and give the total parcel price.

Typical delivery is 10–14 days; non-standard sizes and larger orders may take longer. Your quotation confirms the actual timing.
