The Swarovski 2088 flat back rhinestone is the enhanced cut XIRIUS Rose, improving on the already amazing Swarovski 2058 XILION Rose Flat Back Rhinestone. This revolutionary crystal is named after Sirius, the brightest star in the galaxy. Like all modern Swarovski crystals, the 2088 Xirius flat back is made with the lead-free, superior Advanced Crystal formula, and is manufactured according to the company's strict socially and environmentally responsible standards. Shown in Crystal Orange Glow DeLite and in size SS16. This beautiful Lacquer Pro color from Swarovski is created not by tinting the crystal but instead by using a unique colored foiled which radiates through the clear crystal. This gives a different look compared to traditionally colored crystals.
