1 pcs Red Ruby - 3.69 ct - Asian Institute of Gemological Sciences (AIGS)

Rubies, known as the red variety of the mineral corundum, are among the most sought-after precious gemstones due to their vibrant color and historical significance. This ruby weighs 3.69 carats, making it a substantial size for use in fine jewelry such as rings, pendants, or brooches. Certified by the Asian Institute of Gemological Sciences (AIGS), it ensures the stone's authenticity, quality, and characteristics have been professionally evaluated. The rich red color of a ruby is primarily due to traces of chromium within its crystal structure, with the finest rubies exhibiting a deep 'pigeon blood' hue. Rubies are notably durable, scoring 9 on the Mohs hardness scale, second only to diamonds among natural gems, which means they are well suited for everyday jewelry wear. Their presence in various cultural and historical contexts adds to their lasting allure and value.
