This 10 gross package of 6ss (1.9mm-2.1mm) Crystal AB hotfix rhinestones are Swarovski® 2038 Xilion Rose stones: clear crystals finished with an aurora borealis (AB) coating that throws a rainbow shimmer across the clear base. At this extra-small size they are made for fine detail, small lettering, serifs, tight outlines, and the delicate accents larger stones cannot hold. The heat-activated backing sets fast on heat-safe fabric with an iron or a hotfix applicator. For the same color and size in an in-stock crystal, see MAXIMA Crystals by Preciosa® Hotfix Crystal AB 6ss.
Best for: detailed hotfix transfer work, fine lettering and serifs on iron-on and Silhouette-cut transfers, small outlines, and delicate accents on dance, skating, and costume designs.

What Is AB?
AB stands for aurora borealis, an iridescent coating added over the crystal. It leaves the base color intact and adds a reflective, rainbow-like shimmer on top that shifts as the light and the fabric move. Crystal AB is a clear crystal with that rainbow overlay, one of the most popular finishes for stage and performance work.
Size Reference

This extra-small size is best for detailed hotfix transfer work: fine lettering, serifs, and tight outlines on iron-on and Silhouette-cut transfers, where larger stones cannot hold the detail.

Frequently Asked Questions
What is Crystal AB?
Crystal AB is a clear crystal finished with an aurora borealis coating that adds an iridescent, rainbow shimmer over the clear base. The crystal stays clear underneath; the AB is the reflective overlay on top that shifts color as the light and the design move.
What are 6ss rhinestones best for?
6ss rhinestones, about 1.9mm to 2.1mm, are best for fine detail: small lettering, serifs, tight outlines, and delicate accents where a larger stone would not hold the line. Many makers keep a small size like this on hand for tight spaces and curve fill-ins alongside a larger all-over size.
What is the difference between hotfix and non-hotfix rhinestones?
Hotfix rhinestones have a heat-activated adhesive already on the back, set with an iron or a hotfix applicator on heat-safe fabric. Non-hotfix flatback rhinestones have no adhesive; you glue them on, which suits delicate or non-fabric surfaces and pieces washed only occasionally.
