Feel like a princess with this 14k white gold butterfly ring with opals and tanzanites. The two marquis-shaped opals are a total of 0.50 carats, and the two round-shape tanzanites are a total of 0.20 carats. This ring is the perfect size, and is never in the way or too bulky. Some gemstone rings with a similar design snag on other things and are too heavy to wear comfortably. You will never have that problem with this lovely ring. The setting is also available in white and rose gold, if the default yellow gold doesn't appeal to you. Tanzanite and opals are a lovely combination, and this ring is no exception to that.
