I have made a very pretty multi colored 20in necklace with 9x12mm siam gem cut red beads and 5x8mm siam gem cut rose colored beads and 6mm and 4mm pink gem cut beads, also 4mm square cut red beads and the necklace has silver spacer beads and ice colored beads for added color. The necklace weights 20.8 grams and is on stanless steel coated bead thread. And this is made locally in the u.s.a. by mcm handmade .
