Water Opals with play-of-color

Fascinating Colors on a Clear Watery Surface

 

Mexico is also home of the world’s most beautiful Water Opals. You can find this rare gemstone in great varieties in our vast opal collection.

Water Opals come from the same deposits in the areas around Magdalena and Querétaro as the world-famous Mexican Fire Opals.

Characteristic of this kind of opal is the transparent to translucent bodycolor. This can be clear as water or can have a hint of very pale blue to a very light yellow orange. In addition to this bodycolor, Water Opals can show a wonderful play-of-color consisting of all the colors of the spectrum.

 

 

 

This play-of-color is known as opalescence and is due to the opals contents’ of silica gel and 3 to10% water. Embedded in the silica gel are tiny spheres of christobalith through which the light is refracted and separated into different color beams. The most transparent of these wonderful opals have smaller amounts of silica gel between the spheres.
