Designer Simon Tavassoli of B.B. Simon is known for luxurious, decadent accessories adorned with Swarovski crystals. Worn by celebrities such as Carrie Underwood and Christina Aguilera, original B.B. Simon accessories range in price from around $200 to as much as $35,000 per accessory. As the popularity of B.B. Simon grows, the market to create knockoffs also grows. Knockoffs aren't cheap anymore, and sometimes it can be difficult to identify the real deal from fakes. Use these tips to ensure the sparkly you're about to purchase is a real B.B. Simon.

Check the crystals. B.B. Simon accessories exclusively use Swarovski Elements crystals in their designs. Swarovski crystals bear a small company hallmark inside the crystal. Use a jeweler's loupe to see if that hallmark exists within the crystals in your accessory.

Look for the B.B. Simon hallmark stamped onto the metalwork of your accessory. Like other high-end design houses, B.B. Simon also stamps a hallmark onto each accessory to verify that it is an authentic item. Often located on the metalwork, finding this hallmark is further evidence you've purchased an original piece.

Check the serial numbers. Original B.B. Simon merchandise is issued with documentation, which contains a serial number. You can contact customer service at B.B. Simon to check serial numbers to ensure it is a real B.B. Simon accessory.

Feel the materials. B.B. Simon accessories are known for using high-quality metals, leather and other materials. If the accessory feels cheap and poorly made, you're most likely looking at a fake.

Report retailers selling faux B.B. accessories under the B.B. Simon brand to the company's customer service department.
