COMMON SIZE

COMMON GAUGE
* indicates the most common size - updated 2020Please Note: The post(bar) thickness of 20 gauge(0.8mm) is thinner than 18 gauge(1.0mm). Though it seemingly goes against logic, jewelry gauge sizes actually get thinner the higher the number of the gauge. A 20 gauge earring post is actually thinner than a 18 gauge earring post.
