This wonderful rare material LOOKS LIKE FROZEN ICE! The lines are not fractures, they are natural formation and actually make it looks more icey! Here is your chance to own this very unique and extremely rare opal! Have you ever seen one in a color combination of silver, gold and pink? We have ONLY one of these, so act fast while it’s still here. Please watch the video, it is truly a beautiful stone with its flashing internal bubbles visible under the light. Kindly take note that its back is not fully polished (grind marks visible).

ONE OF THE RAREST GEMS IN THE WORLD. Gem quality hyalite opal that comes in veins thick enough to cut comes from ONLY ONE PLACE ON EARTH a small knoll in southern Utah, and most of it is gone long ago.

This hyalite opal was formed by geyser or hot spring deposits of minerals. Hyalite opal is found in almost all opal deposits in the world but in very thin layers on the other opal or in small seams. The location in Utah where this material comes from is the only known location where this adularescent material comes in veins thick enough for cutting.

It does not have color-play like other opals, instead the light rolls off the internal bubble structure and flashes back at the on-looker.

Weight and size of gemstone/item may vary slightly from piece to piece due to difference in calibration of our weighing and measuring scales compared to those used by buyers.

Colour may also not appear exactly as in real life due to variation in computer monitor resolution and lighting used during photo shooting. Our photos are taken under fluorescent lighting; sometimes Torch Light and Flash Light are also used. We will do our very best to represent the accurate pictures of all our items.
