Stone and Glass Keyhole Weights
The below measurements are approximate:
- Each weight has a 1" external diameter and weighs between 6 grams and 7 grams
- The insertion gap measures 5mm
- The internal diameter measures 5/16"
The wearable area measures at a 2g, but you must measure at 00g/10mm or larger to insert this design.
The glass material weights (opalite and blue goldstone) have rounded edges, and the stone (black agate) has flat edges.
Jewelry is measured through a gauge system (see chart below). The higher the gauge number the smaller the wire is. A standard "earring" is usually 20 gauge. Jewelry gauges/sizes can vary between manufacturers. There is no universal regulation on companies to make a standard size in body jewelry. A big part of this is that some jewelry is made overseas and measured in millimeters. And in the USA jewelry is measured in inches/gauges. So many times jewelry can be anywhere from .5mm to 1mm different.
