Almandine is the most common garnet gemstone. In fact, the deep red color coveted in garnets usually represents a mixture of almandine and pyrope. Available in standard sizes and a wide range of red hues, almandine gems are less expensive than their rarer cousins. They also possess a hardness of 7-7.5.
