A ruby's price is based on its beauty, quality, cut, and carat weight. Because they are rare and have strong beauty, rubies can sometimes fetch more money than diamonds. Rubies are extremely rare stones linked to bright energy and high sensuality. Rubies are astrologically reliable and, therefore, connected with wealth, royalty, and power dynamics for a long time. The cost of a gem is based on four main elements: color, clarity, cut, and carat weight.
