Frequently Asked Questions
What color is Sapphire in rhinestones?
Sapphire is a deep, rich blue with strong jewel-toned saturation. It reads as a classic, pure blue under stage and natural lighting, darker and more intense than Light Sapphire and distinctly bluer than Montana. It is one of the most versatile and widely used blue shades in the rhinestone palette.
What is 6ss in millimeters?
6ss rhinestones measure approximately 1.9mm – 2.1mm. They are one of the smallest flatback sizes available, best for fine detail work, intricate patterns, nail art, and designs where larger stones would not fit.
What is the difference between hotfix and non-hotfix rhinestones?
Hotfix rhinestones have a heat-activated adhesive pre-applied to the back. Non-hotfix rhinestones have no adhesive and are applied with glue. Hotfix is a good choice for fabric projects where a fast, clean bond is the priority. Non-hotfix gives more flexibility across different surfaces and adhesives.
