This lovely little piece was hard to photograph! This one has an interior band of blue while the outer side is a dark blue/purple, though the fun is that not all of the original outside blue came out of the cut so it has a neat looking 'texture' in some places.

This one is a little over 1/8" wide and a size 7 3/4 and is for sale for $75 plus shipping

These are hand lathed from solid Grade 9 Titanium stock and then hand polished and anodized (and usually lightly polished again)
