Judging from the clasp. This piece was purchased in Belaggio Jewelers in Las Vegas for $6,000. There was an insistence on uniformity of color, luster, size, & complexion. The rarity lies in the superlative skin of the pearls - they're just perfect. The dusky pink flows from pearl to pearl as if they were all born in the same oyster. The handmade gold clasp contains 120 single-cut diamonds.
