Overview

Enhanced blue diamonds are natural diamonds that have undergone color enhancement treatments. Such methods, usually irradiation, transform the otherwise colorless precious stone into a vibrant shade of blue. These treatments are typically permanent and do not damage the diamond’s chemical structure.

Untreated, natural blue diamonds can be found, but they are extremely rare. This scarcity makes them one of the most sought-after and expensive gemstones available today. The jaw-dropping Hope Diamond, weighing over 45 carats and insured for US $250 million, is a fine example.
