Gemstone Education: Rubies - Quality Factors

Color and Clarity
The value of a ruby is highly dependent on its color, with the most prized rubies displaying a saturated, bright red without any overtones. Clarity also plays a significant role, though rubies without any visible inclusions are exceedingly rare.
Cut and Carat Weight
The cut of a ruby is essential to enhancing its color, brightness, and overall visual appeal. Carat weight, like with other gemstones, significantly impacts the value, with larger rubies typically being much rarer and more valuable.
