Publisher-provided text

carat_to_mm Diameter in millimetres for a given carat weight. Round brilliant cut. Density-corrected per stone - a diamond chart is wrong for moissanite by ~9%.
mm_to_carat Carat weight for a given diameter in millimetres. Round brilliant cut.
grading_scale GIA colour (D-K) or clarity (FL-SI) scale as used for moissanite, or published optical constants for moissanite / diamond / cubic zirconia.
ring_size_convert Convert a ring size between US, UK, EU (ISO 8653) and inner diameter in mm. A US 6 is a UK M, not a UK 6.
necklace_length Where a necklace of a given length sits, with the trade name (choker, princess, matinee...).
stud_appearance How a round stud of a given stone diameter reads on the ear.
