Introduction to Round Ruby Corundum

Round ruby corundum is a highly sought - after gemstone in the jewelry industry. Corundum is a crystalline form of aluminum oxide ((Al_2O_3)).

The round cut of ruby corundum is a classic and popular choice. It maximizes the brilliance and fire of the gemstone by using a specific faceting pattern. The round shape has a timeless appeal, making it suitable for a wide range of jewelry designs, from engagement rings to necklaces and earrings.
