Diameters are approximate and can vary slightly from batch to batch:
14g thru 8g have a 1-3/16" diameter
6g and 4g have a 1-3/8" diameter
2g and 0g have a 1-1/2" diameter
These are all hand made and matched the best they can be. Each piece will vary a bit as it's impossible to have two identical pieces.
THIS IS A LIMITED ITEM!
Limited jewelry is usually re-stocked much less frequently and is harder for us to get from the manufacturer. So get it while you can, while it's available!
