Things You'll Need
Instructions
Look for bubbles. Swarovski crystals have no bubbles within the glass, so if you find bubbles, it is not authentic.
Notice the luster. Swarovski crystals have a uniform luster, with no oily looking finish. Imitations will often have minor imperfections and scratches that come from lesser quality.
Look for that extra sparkle. Swarovski crystals with have much more sparkle than a fake, especially when observed in sunlight. The depth of color will be especially noticeable when compared to a fake.
Examine the packaging. If you are lucky enough to have the original packaging, look for a silver-toned hologram with "Swarovski Elements" printed on it.
Look for the logo. Originally the logo was a flower, which was then replaced by the letters "S.A.L" The current logo is a swan, but it is slowly being phased out in favor of simply the name Swarovski.
Take the object to an expert. If you are still in doubt whether your crystal is genuine Swarovski or not, get the advice of an expert such as an antique or jewelry dealer.
