This listing is for beautiful 6mm or 8mm blue agate gemstone beads to be wire wrapped in 20 gauge sterling silver. There are some variations in the color of the gemstone & they have dark inclusions. The wire I use is solid Argentium sterling silver. Argentium sterling silver is more pure than traditional sterling silver (935 vs 925). Argentium is brighter, stronger, more tarnish resistant & is made from ethically sourced silver. It is also nickel free & hypoallergenic.
