Beguiling in bright blue, her december birthstone is magnificent at the center of this pendant. Hanging below a coiled, sterling silver bale, three round diamonds glow. This design leads up to an 8. 0mm round blue topaz encircled by a lasso of 10k gold. Regal and charming, this pendant gracefully suspends from an 18. 0-inch rope chain with a spring-ring clasp.
