Natural Opal - Modern Gem Jewelry

Natural Opal

Natural opals are usually described as light, dark/black, boulder, and matrix. Although boulder opal has an ironstone backing, it is regarded as a solid natural opal because this backing occurs naturally. The variety of natural opal is determined by the two characteristics of body tone and transparency.
