Ruby is celebrated as the most precious of all gemstones and comes in many shades of red. The red color in rubies is primarily a result of the presence of chromium. Prized for their beauty, durability, and rarity, it is the quality of the color, which most determines the value of the stone.

All natural ruby gemstones are crafted to the most precise specifications and uniformed in terms of brilliance, color, clarity, dimensions and shape. To offer maximum consistency and quality, all rough rubies are sourced from our own mines or from the most reliable suppliers in the industry.
