DiamondTrade / 20
One shape, two origins
Shape describes a diamond’s outline. Natural or laboratory-grown origin is a separate criterion. Choose a shape, then compare actual measurements, colour, clarity, cut and report. Matching carat weight does not mean matching visible size.

Sourcing for a particular setting
For an existing setting, start with the acceptable measurements. For a new design, compare outlines at a consistent budget and discuss mounting with a jeweller. Use the individual stone’s video to assess its facet pattern and light distribution.
