Chlorphane from the Erongo Mountains in Namibia. These are incredibly phosphorescent and this one is an absolute stunner, with great color and awesome modified corners. 36.3 ct. $140. Available at @over_100_dollar_gems

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!
