章節 95: Chapter 95: Opal Wands

Opal wands contain one or more opals: a large one for the wand's end cap, a small one at the wand's tip, or small ones along the wand's length.

Opal

Opal is a precious stone consisting of silica that contains 3-21% water. Opal's internal structure of microscopic silica spheres packed in a hexagonal or cubic lattice causes it to diffract light of various colors, typically green, blue, and red. Most opals are carved and polished to form cabochons, although certain opals (especially fire opals) are sometimes faceted.

Black opals are the most precious form of opal. It has a dark black or blue matrix that emphasizes the opal's naturally bright colors. Black opals are primarily found in Australia, Egypt, and Nevada.
