Preciosa Viva Rosemontee Sapphire Aurora Borealis Finish 4mm

These are Preciosa Viva Rosemontee sew-on stones — 4mm Sapphire AB crystals permanently set in brass findings, sold in a pack of 144. The brass setting gives you a ready-to-stitch base, so the sparkle goes straight onto your work without extra prep.

Sapphire runs a deep, cool blue, and the Aurora Borealis coating lays an iridescent rainbow shift over the top — the kind that moves from blue to violet to green depending on the light hitting it.

What to make with them

Stitch them onto fabric for tambour-style embroidery, scatter them across a beaded bodice, or line them along the edges of a structured bag for a clean row of shifting blue light. At 4mm they're small enough to work in tight grid patterns but substantial enough to read clearly from a distance.
