Found in virtually every color imaginable, precious gemstones infuse fine jewelry with a natural brilliance. Whether adorning a pair of stud earrings, a tennis bracelet, or even an engagement ring, a radiant gemstone lends visual interest to any precious metal setting, especially when alternating with diamonds. Since ancient times, gemstones have served as striking symbols to commemorate special events and milestones. Many gemstones are officially recognized as birthstones for certain months of the year, and others commemorate specific wedding anniversaries and have become ideal jewelry gifts for those occasions.
