These necklaces are made completely of vintage Swarovski rose aurora borealis margaritas. These fabulous crystals, shaped like snowflakes or flowers (depending on whether you're a winter or a summer person :-)), are fundamentally rivoli crystals with scalloped edges. They come to a central point both front and back, and have facets radiating out like rays from the centers. This type of faceting gives greater depth and sparkle to a crystal than any other, in my opinion. I think that margaritas are one of the greatest designs created by Swarovski. These crystals are dazzling. I spaced them with just enough silvery glass seed beads to separate the crystals. I've shown both sides of the necklaces, because they're both equally beautiful; each is practically two necklaces in one. These necklaces feature the margaritas in two different sizes, 10 mm (if you like delicate) and 16 mm (if you like big). I also have these crystals in 12 and 14 mm, if you'd prefer one of those sizes. The necklace is 16 inches long, with a 3-inch extender, giving it a working length of 16-19 inches. Signed RLN.
