PLEASE NOTE: This item is crafted from organic material and the gauge can vary +/- up to 0.5mm
In our drop-down menus for adding to cart, we show the gauge of the item you are ordering, then the length/diameter, then the ball size if it has any:

Jewelry is measured through a gauge system (conversion chart below). The higher the gauge number the smaller the wire is. For reference, a standard "earring" is usually 20 gauge. Jewelry gauges can vary between manufacturers. There is no universal regulation on companies to make a standard size in body jewelry. This is because some jewelry is made outside of the USA and measured in millimeters. And in the USA jewelry is measured in inches.

Rings

Rings are an essential item that can be worn in many piercings. They come in various styles:
  • Captive bead rings - These use tension to hold a bead in place.
  • Clickers - These use a hinge to open and close the ring.
  • Segment rings - These have a "segment" that comes completely out of the jewelry similar to removing a bead. But it looks like a completely seamless piece of jewelry.
  • Seamless rings - These rings require bending to open & close.

Verified purchase 2-1/2"  Picasso Jasper (pair)
Beautiful stone, actually seemed to have more character and color variation than even the photos suggested. (Slight creme/yellows in the whites) and a very well matched set.

Verified purchase 1-1/2"  Opalite (pair)
I love Oracle. Straight up. Huge flares, fat concave, buttery smooth surface, and beautiful cut of opalite! 10/10 would buy again.

Verified purchase 1-5/8"  Bloodstone (pair)
I don't want to sound picky, because I love Oracle.. but I'm a little disappointed in the cut. I guess I just didn't get the luck of the draw, but it's an all brown cut with yellow accents and one green spot. Meh. The actual craftsmanship is unreal, and they're beautiful.. just kind of what I was hoping I wasn't going to get (if that makes sense).
