Frequently Asked Questions

What color is Siam in rhinestones?

Siam is a deep, rich ruby-red with classic jewel-toned clarity. It reads as a true, saturated red under stage and natural lighting, darker and more jewel-toned than Light Siam and distinctly more red than rose shades. It is one of the most widely used red shades in dance, costume, and pageant designs.

What is the difference between Siam and Light Siam?

Siam is a deep, rich ruby-red with strong jewel-toned saturation. Light Siam is a brighter, warmer red with more orange-red quality and less depth. Side by side, Siam reads as the classic, darker jewel red while Light Siam reads as the more vibrant, fire-engine red of the two.

What is 10ss in millimeters?

10ss rhinestones measure approximately 2.7mm – 2.9mm. They are a good choice for outlines, accent rows, and nail art where you need slightly more visibility than extra-small sizes without moving into mid-sized coverage territory.
