Sold! 5 Vivianites from Bolivia! Good clarity on these and show the blue color when you change the axis with light behind it! $100! That’s $20/each

This is a very nice opal on matrix from a rare locality! From Spencer Idaho; this area produces some really amazing opal! I got this piece a little wet to show off the colors and the flash a little better. But amazing coverage of color all over the piece! $90!
