章節 88: Chapter 88: Blue Sapphire Wands

Blue sapphire wands contain one or more blue sapphires: 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.

Blue Sapphire

Corundum is a colorless type of aluminum oxide Al2O3. When corundum contains trace amounts of impurities (such as iron, titanium, and chromium), you obtain different colors of sapphires such as blue, green, yellow, orange, pink, and purple. Rubies are the red version of corundum and contain trace amounts of chromium.

Sapphire is the blue variety of the mineral corundum. It is the most famous gemstone, both rare and beautiful. It is hard and durable, being the second hardest mineral after diamonds. Sapphires come in numerous colors, but arguably the most stunning are the blue sapphires.

Some sapphires, called star sapphires, contain unusual tiny needle-like inclusions, which intersect each other at varying angles. These inclusions result in six intersecting rays, a phenomenon called asterism.
