This results in the magnificent display of colors, known as opalescence, which can encompass a range of hues, from blues and greens to fiery reds and oranges.
Classification of gemstones
Gemstones are classified based on several criteria, including their composition, hardness, and optical properties. Opals are categorized under the mineraloid class, as they lack a specific crystal structure. Within the opal group, there are several varieties, including precious opal, which displays a vibrant play of color, and common opal, which lacks this feature. Additionally, there are unique forms, such as fire opal, known for its warm, translucent orange and yellow shades.
Properties of Gemstones
Physical properties
Opals possess several physical properties that make them distinct. Their hardness ranges from 5.5 to 6.5 on the Mohs scale, making them relatively soft compared to other gemstones. This characteristic requires careful handling to prevent scratches and damage. Furthermore, opals can display a changing appearance when viewed from different angles, a trait attributed to their internal structure that refracts light at various wavelengths.
