This hand-strung, Yellow Topaz and Aquamarine necklace is a study in light shades that accentuate one another. Aquamarine is the birthstone for October in the Hebrew, Roman, and Arabic traditions, and has been associated over time with calming, mental clarity, and meditation; Yellow Topaz is the birthstone for November, and is associated with reversing the aging process, releasing tension, spiritual rejuvenation, and feelings of joy.
