Crystal Boulder Opal Heart 

This Hand Carved Crystal Boulder Opal Heart is such an amazing specimen, a large sized heart for a collector, pendant necklace or gift for your significant other on valentines day or anniversary. It is a Natural Solid Genuine Crystal Boulder Opal Loose Stone From Winton, QLD, Australia

We had this opal carved by one of the best opal carvers in the World. It is very difficult for a lot of opal cutters to be able to carve such nice, unique shapes such as this one. 

This opals discovery was west of Winton in Diamantina. This opal was obviously not found in its current shape of a heart.

What are Crystal Boulder Opals?

Crystal Boulder Opal, also known as P!pe Crystal Boulder Opal, is a unique type of opal that is based on sandstone instead of the more commonly known ironstone. Unlike ironstone, sandstone is a more fragile and brittle material. This results in a lighter-colored opal that has a crystal-like appearance.

Crystal Boulder Opal discoveries are sometimes unintentional while searching for Ironstone Boulder Opals. These opals are found in sandstone, which is a sedimentary rock composed of sand-sized mineral particles or rock fragments, and are typically located in small pockets within the sandstone. Unlike Ironstone Boulder Opals discoveries, which often require smashing open with a sledgehammer. These types of opals discoveries are sometimes without any extensive effort. The discovery of opals in sandstone can be quite exciting, as these unique gems can display a range of colors and patterns. They can become a prized possession for collectors and jewelry enthusiasts alike.
