1. What is the July Birthstone?

Ruby, the July birthstone, is a type of corundum mineral that contains traces of chromium, which gives it its red color. The more chromium a stone contains, the darker red it appears. Chromium can also cause red fluorescence (a visible light emitted temporarily by certain gemstone materials when exposed to high-energy sources such as ultraviolet light (such as sunlight), X-rays, or lasers), which makes the red color more vivid.

The name ruby is derived from the Latin "Ruber", meaning red. Known as the "king of gemstones", ruby is famous for its rarity and hardness, so most ruby jewelry on sale is made from lab ruby.
