Frequently Asked Questions
What does Crystal Unfoiled mean?
Crystal Unfoiled rhinestones have no metallic foil on the back of the stone. Standard rhinestones use a foil backing to reflect light forward. Unfoiled stones stay transparent, so light passes through rather than bouncing back. This makes them the right choice for sheer fabric, mesh, and see-through panels where a foil backing would be visible.
What are 30ss unfoiled rhinestones best for?
30ss unfoiled rhinestones are a strong choice for bold statement accents, costume borders, and scattered large stones on sheer or mesh fabric. At 6.3mm – 6.5mm, they read clearly under stage lights, and the unfoiled backing keeps the look clean and translucent on see-through panels.
How many 30ss rhinestones do I need for a project?
It depends on your design, but 30ss stones cover less area per gross than smaller sizes. A 0.5 gross (72 pieces) works well for accents and borders on a single costume piece. A 2-gross (288 pieces) pack suits larger coverage areas or multiple pieces. Use our rhinestone estimating guide for a more precise count based on your project dimensions.
