Japanese 10-in-2 got its name because in every two flat or horizontally-situated rings (the teal ones in this case) are ten rings. This chainmaille pendant is made with sterling silver and anodized niobium jump rings.
Niobium is a hypoallergenic pure element; #41 on the periodic table. The process of anodization adds color by creating an oxide layer with electricity, which allows the eye to see color. This means no dyes are used, and the resulting finish is iridescent and very scratch-resistant, especially when compared to other weaker metals.
Niobium is heavier than steel, which means pieces made with that material have a satisfying weight when worn.
The anodized niobium in this piece is teal. Each ring has its own iridescent sheen - some teal rings take on a bit of green or purple. It's really quite beautiful.
There is a small rose quartz bead in the center of this pendant which helps it maintain its shape.
