Jewelry design guides
From ring sizes to gold weight: what you need at the design bench every day. The numbers are the values the Kumpix engine uses and measures.
Ring size chart: inside diameter for US, EU and Turkish sizes
Inside diameter and circumference in millimeters for US, European and Turkish ring sizes. The same table Kumpix uses when it builds a ring.
14K, 18K and 22K gold weight: from volume to grams
The weight of a piece is its metal volume times the density of the alloy. Densities of 14K, 18K and 22K gold, platinum and silver, with measured examples.
Minimum wall thickness for casting: gold, silver, platinum
How thin can a casting model be? The minimum and safe wall thickness per metal that the Kumpix casting check uses, and how the check decides.
