Opals had fascinated people for centuries. “Inside them you can see the vivid fire from rubies, the glorious purple of amethysts, the ocean green of the emeralds, all together shining in a beautiful mix of iridescent lights”.
The quality of an opal is measure by the purity of its crystals, transparency, its colors, iridescence, and the shape, it could have.
The Mexican opal is amorphous, it lacks a crystalline structure. However, it has an internal arrangement consisting of tiny, narrowly packaged amorphous silica spheres. Through the years, this stone has been all around the world, charming for its beauty and mysterious that intrigue anyone who see it.
The most opal consuming countries are Japan, Germany, United States, Korea, Swiss, France and Italy.
The piece (with the opal inside) is removed in the form of a specimen, from various mines, then start with its transformation, beginning with the separation of the excess rock using a circular cutter with a diamond disk.
After obtaining the pure opal, as a second step, its shaped in a “forge” (that is a stone emery in water), where the stone is given the form that is required.
Thus, it is sent to the next phase which consists of a process of sand downing the opal with three sandpapers of different grain graduation.
To finally pass it to the luster by means of a circular ramrod and a powder of selenium dioxide which gives the natural shine to the crystal and therefore, it´s how the Opal shows its best colors.
