Preciosa Hot fix crystals feature a precision 12 facet cut. Their table (top) is large creating extra light reflection. They feature a silver foil flat back for extra reflection and a pre-coated heat activated glue on the underside of the stone for hotfix application.
The Mesmera rhinestones feature a new Color Shift Technology. Developed by Preciosa with the Czech Academy of Science the stones contain a rare mineral that causes the color shift. As a result, like a mood ring, the stones change colors under different light conditions. The color changes from purple, to green, to pale blue. See the photo.
