The vintage acrylic pearls are a whopping 20mm in diameter. I've wrapped five of them with tiny silvery seed beads and 3mm light Colorado topaz round Swarovski crystal beads, then hooked the five together using 6mm crystals of the same colour. The strand is quite long -- over 8"; but with beads this large, when you bend them into a circle, the inside measurement is deceptively small; in this case, about 6-1/2" or a good fit for a normal-sized wrist. The clasp is a gold plated safety catch. Such an innovative design would have to come from SPARKLE PLENTY! All of our one of a kind and limited edition artisan beaded jewelry is individually handcrafted in our studio in Los Angeles, California.
