Shape guide

Shapes.

What each cut is called, how it is measured and drilled, and what makers use it for. The same stone reads differently as a rondelle, a briolette or a dagger; pick the shape for the piece first, then the stone.

Reading a size.

Round shapes are given by diameter. Everything else is width by length in millimeters, so a 6x9mm pear is 6mm across and 9mm tall. Natural stones vary, so a 4mm strand runs roughly 3.5 to 4.5mm.

Center drilled

The hole runs through the long axis. Rondelles, rounds, ovals, tubes and cubes. Strung end to end.

Top drilled

The hole runs across the narrow top so the bead hangs. Pears, tear drops, hearts, marquise and daggers. Fringe and earrings.

Flat and stacked

Thin discs strung edge to edge so the strand reads as one column of color. Heishi and coins.
