These are Preciosa Viva Rosemontées — foil-backed crystal stones set in a brass base with two holes for stitching directly onto fabric or other surfaces. The AB coating pushes the aqua base into a full rainbow shift, making each stone read differently depending on the light angle.

Aqua glass crystal with a permanent Aurora Borealis top coating that layers iridescent green, violet, and gold over the cool blue-green base — high sparkle with serious color movement.

What to make with them

Stitch them onto swimwear, bridal bodices, or dance costumes where the AB shift catches stage or natural light. They also work beautifully hand-sewn onto ribbon chokers or leather cuffs for a mermaidcore accent that holds up over time thanks to the permanent coating and brass setting.
