Description

Ruby is admired for its rich color, brilliance, and rarity. Fine-quality natural rubies are significantly rarer than most other colored gemstones, especially in larger sizes. Natural inclusions are common, but high-quality rubies combine strong color with good transparency and minimal eye-visible inclusions.
