Opal Rough- 12.7 g

Opal rough refers to opal in its uncut, natural state as it is found in the earth before any shaping or polishing has been done. Opal is a hydrated amorphous form of silica, known for its remarkable play of color, which is caused by the diffraction of light within its silica spheres. Rough opal typically exhibits a milky or translucent base with flashes of various colors that shift as the stone is moved. This raw form is prized by gem cutters and collectors who value the natural beauty and potential of the stone. Opal formation occurs in sedimentary rock environments, especially in places like Australia, Ethiopia, and Mexico, through the deposition of silica-rich solutions in cracks and cavities over millions of years. Collecting opal rough provides an authentic experience of this unique gemstone's natural state, making it appealing both for jewelry makers and mineral enthusiasts.
