360 ct - HUGE Untreated Ruby - Rough- 72 g

Ruby is a variety of the mineral corundum distinguished by its rich red color, owed to traces of chromium. A ruby of 360 carats is a substantial specimen, especially if untreated and in rough form, meaning it has not been cut or polished. Rubies are among the most valuable gemstones, prized for their color, hardness, and rarity. Rough rubies provide insight into the crystal's structure and original formation conditions. Large untreated rough rubies are particularly significant for collectors and gemologists because treatment can alter a stone’s natural appearance. Such a specimen represents both natural beauty and potential for cutting into gemstones or for mineral study.
