Jewelry can either have a work of art attribute, a commodity value or a blend of both.

JEWELRY AS A WORK OF ART

There are genres of jewelry considered as works of art where gemstone (commodity) value can play very little or no role. Examples would include (and not limited to) very well made antique jewelry, Castellani, Tiffany plique-au-jour, very well made signed & un-signed art nouveau and deco jewelry without large gemstones, Suzanne Belperron, Rene Boivin, Verdura, Lalique, David Webb and Seaman Schepps among many others.

Values for jewelry considered purely as a work of art are derived by from sales data within the relevant marketplace.

JEWELRY AS A COMMODITY

This is where a jewel is valued in the appropriate market for its precious metal and gemstone content only.
