One of the most popular gemstones, not only for brides and bridesmaids for a Hawaii beach wedding, is the beautiful rainbow moonstone. It has a slight blue shimmer when light refracts of it, reminiscent of the moonlight. This beautiful bracelet is made out of faceted moonstone, crowned with an intricately carved bead in 22 karat vermeil. The chain and clasp are 14 karat gold fill, and the bracelet is adjustable from 7.5 to 8.5 inches ( 19 - 21.5 centimeters ).
