These beautiful faceted chrysoprase stone works as the lock in these captive bead piercing rings. Chrysoprase is the May birthstone (together with Emerald).
I make the rings with the inner diameters 8, 10, and 12mm. You can choose if you want a ring in sterling silver or blackened niobium wire with 1mm (18g), 1.2mm (16g) or 1.6mm thickness. The beads are 4mm in diameter and range from really pale green to dark brownish green with most of them having a greenish turquoise color.
I have divided them into five different categories, as you can see in the last two pictures. 1 - light color, 2 - medium color, 3 - dark color, 4 - with matrix (SOLD OUT), 5 - brownish color.
When you order, choose in the second option if you want the ring to be black nibium or sterling silver and the color (1-5) that you'd like the bead to have.
