These are Preciosa Rosemontee sew-on stones — 3mm faceted crystal set in a silver-toned brass base with holes for stitching directly onto your work. At 144 pieces, you have enough to commit to a full design without rationing every stone.

The opaque black finish is solid and fully saturated, absorbing light rather than reflecting it — giving finished pieces a matte-dark, graphic quality that reads sharp against pale or metallic materials.

What to make with them

Stitch them in tight grids onto corset panels, jacket lapels, or cuffs for structured embellishment, or scatter them across a veil or sheer fabric for a constellation effect with serious edge. They're also a natural fit for bookbinding accents and leather goods where you want a fastened, permanent detail.
