This is the best known of the Swarovski Crystal Components and is used in all sorts of beading jewellery and fashion accessories from handbags to wedding dresses. The Article number is 5301 however Swarovski is in the process of changing over to a new Article number 5328 to replace 5301 with more facets. The new shape is very close to the original and does not look out of place when the two Articles are mixed. A close examination will reveal a better refraction of light and unlike the 5301 which has been copied by many other companies, the 5328 is copyrighted.
