Boulder opal is a different species than the other two main types of opal: black opal and White opal. Boulder opal is widely sold in opal earrings as a free component of gemstone. That means the stone has an individual shape rather than an oval or a circle or a pear shape in which black and white opals are usually cut.
The free form layout will not look like any other shape you notice but will still be fun. Another major difference is that boulder opal is usually not smooth and top notch. We call this a cabochon from an old French word that translates into the English word hat. Cut many opals into cabochons because they enhance their color features by allowing light to enter and exit the stone for maximum effect.
Boulder opal jewelry will usually have a fixed bed of opal sitting on a bed or a dark brown stone. This means that the stone will need the craftsman to make a special stone setting because the ready-made or molded settings usually come in oval cuts made of stone cabochon cuts and not free-form opal stone.
There are two subtypes of stone opal: seam and matrix. When the metal is broken by running the tractor across or hitting it with a large hammer the rock will split into two parts. Opal will be in each section.
Matrix opal is where opal works randomly across the rock. Boulder opal is heavier than black opal or white opal because it usually has a metal stone so it makes it very difficult to make other types of opal jewelry such as opal rings or opal earrings. It is certainly impossible to do anything without hanging paint is good and makes
