One piece can combine a steel post, a plated setting and a stone accent. Compare the details by style when building a retail assortment.

Metals & finishes

The base metal forms the piece. A gold-plated finish adds a layer of gold over that base, while gold-tone describes the color. A steel grade such as 316L identifies the alloy. Record the base and finish separately on a line sheet.

Stones & piercing sizes

CZ stands for cubic zirconia. GNJ also lists synthetic opal on selected styles. For a piercing, gauge describes the thickness of the part that passes through the piercing. Specify the wearable length or hoop diameter separately.

Wood, acrylic & silicone

A tunnel can be made of wood, while a clear retainer can use flexible acrylic. A bracelet may combine a silicone band with a steel plate. For a mixed-material style, name the material of each component on the packaging brief.

Materials on the test reports

These are the material descriptions submitted with two GNJ samples. The SGS results cover total lead and cadmium in the components identified in each report.
