Jade is the stone given in celebration of the 12th, 30th, and 35th anniversaries of marriage. For thousands of years, the stone has been revered in China and other countries throughout the world. Brown gemstones are gaining in popularity and smoky quartz is an affordable choice. A smoky quartz ring goes well with autumn colors and evening wear. Sapphire is the birthstone of September, and one of the most popular gemstones on the jewelry scene today. The deep blue color of a sapphire ring is just right for an evening out.
