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. A long time favorite of jewelry designers, aquamarine is the birthstone of March. The diamond-like brilliance of an aquamarine ring is sure to attract attention. Once considered more valuable than diamonds, a peridot ring is a must have. This "gem of the sun" is the birthstone of August and is a beautiful match for the lush green tapestry of late summer.
