Calibrated Parcel Specification Template

A complete calibrated parcel specification has eight fields. Copy the block below into your enquiry email and fill in every line. A complete specification gets a firm quote; a partial one gets clarifying questions or silent assumptions.

The template

Calibrated parcel specification

1. Shape:
2. Size range (mm, min-max):
3. Tolerance (permitted deviation per stone, e.g. +/-0.02 mm on diameter):
4. Colour band (e.g. F-G):
5. Clarity band (e.g. VS, VS-SI):
6. Quantity per size (pieces in each size):
7. Certification and growth method:
   (IGI or GIA; CVD or HPHT; treated or as-grown;
    certified per stone, per parcel, or graded uncertified supply)
8. Delivery format (parcel papers, sealed packets, layout-ready sets; courier, insurance and tracking requirements):

Reference design or CAD (if the parcel fits a specific mounting):
Target delivery date and destination:

Field notes

Field	Why it matters
Shape	Cutting programmes are shape-specific.
Size range	Sieving and sorting happen within a range; state minimum and maximum dimensions in millimetres.
Tolerance	Determines how uniform the parcel is. If you do not state one, the manufacturer applies a default that may not match your CAD model or mounting.
Colour band	Single grades make parcels slow or impossible to fill; bands (for example F-G) let the parcel be assembled from normal production flow.
Clarity band	Same logic as colour: bands, not points.
Quantity per size	Decides whether your parcel is a stock pull or a production run.
Certification and growth method	Changes pricing and documentation. State treatment preference (as-grown or treated) explicitly if your end client has a disclosure policy.
Delivery format	Prevents repacking work at your bench.

What happens next

Send the completed specification with your enquiry. We confirm the specification in writing before quoting, so the tolerance, bands and delivery format quoted are the ones you wrote. Stock and standard calibrated parcels typically dispatch within 2-3 working days; bespoke custom-cut or calibrated-layout production typically takes 7-10 working days.
