Swarovski Crystal Pearls
Why are they called “crystal” pearls? It` because they have a heart of an actual crystal ead that has been finished with layers of highly luminous pearlescence. The result is the look of a fine South Seas pearl.
Each Swarovski Pearl begins with a crystal sphere that gives the pearl its ideal weight. Then, each Swarovski Crystal Pearl bead is uniformly coated with iridescent, mother-of-pearl like layers. The even coating combined with the crystal base of the pearl beads give them a luminosity and luster similar to that of real pearls.
The advantage of Swarovski Pearls to real pearls is not just their price. These pearls are abrasion-proof, resistant to perfume, perspiration, electroplating, UV light and scratches. They can be washed and dry cleaned.
With jewelry made using crystal pearls from Swarovski you can have this same consistency, and because the crystal pearls in your necklace, earring, bracelet, or choker is covered in mother-of-pearl like layers, they will look like the most expensive pearls you can buy.
