Made to honor a special day in September- a birthday, an anniversary, or even a day when the deep blue Autumn sky is at its finest (yes, the sky really is bluer in the Fall) or to celebrate the 10th year of marriage. (Blue sapphire is the anniversary gemstone for one decade!) The 3.75 mm faceted ethically sourced sapphire is set in recycled, 14K yellow gold. The one-half inch pendant hangs from a 14K gold cable chain (choose 16 or 18-inch length at checkout). If you have a chain or would rather choose a different style you can purchase it as a pendant only. This is the 7th in the River Rock series and the first in gold. The organic pendant shape is named after the rocks that you see that you can't help but pick up because they've been worn so smooth, almost symmetrical, and more beautiful over time.
