I bought 3...the lapis, aqumarine(for a gift), and the tourmaline. All are fabulous, but my favorite is the lapis. The pearls are a good size, just not very consistent. The one with the tourmaline seems half the size of the other two. Regardless, all have good luster and are 100% nacre. The size of the stones are perfectly proportionate to the pearl IMO. Someone is getting me the all pearl as a gift. Great value!
