This is a cute miniature, showing Topaz on both sides of the matrix, with the Hyaline opal present on the primary crystal. I found this in our "unprepped," area of stock we purchased from Hawthorneden. This piece was part of a lot purchased in the 70's. This material has not been prevalent on the market for quite a long time. On the back side of the primary crystal, there is a very tiny ding that is invisible when displaying it normally.
