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 widely used blue shades in the rhinestone palette.
What is 10ss in millimeters?
10ss rhinestones measure approximately 2.7mm – 2.9mm. They sit between the extra-small 7ss and the small 12ss, making them a good choice for outlines, accent rows, and nail art where you need slightly more presence than the tiniest sizes.
What is the difference between Sapphire and Light Sapphire?
Sapphire is a deep, saturated blue with strong jewel-toned intensity. Light Sapphire is softer and more pastel, with a cooler, airier quality. Side by side, Sapphire reads as bold and rich while Light Sapphire reads as delicate and understated.
