クリスタルオパールジェムストーン

Australian Crystal Opal Gemstones are a Solid Opal variant that are hosted in a transparent body of silicon - allowing environmental light to pass through the opal and interact more directly with the opal's colour patterns when compared to other forms of solid opal.

This trait allows the crystal opals to display some of the greatest ranges of colour variation amoung all types of opal.
