Jewelry Stores Industry Terminology

Alloy

A mixture of metals engineered to achieve desired color, hardness, durability, and price in jewelry manufacturing.

14K gold is an alloy that’s 58.5% pure gold; Adding palladium creates white gold alloys; Jewelers choose harder alloys for prong durability.

Appraisal

The white-light return from a gemstone, primarily governed by cut quality and cleanliness.

Excellent cut increases brilliance; A dirty pavilion reduces perceived brilliance; Round brilliant cuts are designed to maximize brilliance.

Carat

A unit of mass used for gemstones equal to 0.20 grams; not a size measure, though weight correlates with dimensions.

A 1.00 ct diamond weighs 0.20 grams; TCW (total carat weight) for a pavé band is 0.35 ct; Price per carat often increases nonlinearly with size.

Clarity

A grading of internal (inclusions) and external (blemishes) characteristics in gems; impacts appearance and value.

VS1 clarity is typically eye-clean; Plot inclusions at 10x on the grading report; Lower clarity can still look great if inclusions are off-center.
