These 4mm Preciosa Ornela machine-cut crystal diamonds in Dia Siam come 144 pieces to a pack — enough to make a serious dent in a necklace, bracelet, or earring project without running short mid-row. Cut in Bohemia from genuine glass crystal, they carry that sharp, light-catching geometry that only precision machine cutting delivers.

Dia Siam is a deep, saturated red in transparent glass, so the color glows from within and your stringing material or thread color will show through — worth keeping in mind when you choose your foundation.

What to make with them

The diamond shape shines in right-angle weave and peyote combinations where the faceted profile catches light at every turn; they're equally strong strung solo on fine wire or silk for a clean, graphic line bracelet or drop earrings that let the cut do all the work.
