Swarovski rings

Swarovski crystals

— in this case, crystals, usually, mean rhinestones — an imitation of precious stones made of heavy glass or other similar material. The similarity of rhinestones with more expensive stones (up to diamonds) is ensured by the fact that they have high dispersion rates and beautifully refract light, creating iridescent reflections. Often such crystals are, in fact, cubic zirkonia (see the relevant paragraph), and stand out in a separate category solely due to the fact that they are released under the Swarovski brand. This company is, among other things, the most famous manufacturer of rhinestones, and their products are often considered the highest quality (for which there are many reasons).

Due to their low cost, Swarovski crystals are popular in inexpensive jewelry, but the matter is not limited to this — such inserts are also found in mid-range jewelry.
