These sparkling diamond like kiln-safe lab created gem stones can be pushed into the wet clay and fired in place.
Economy pack, you get 20 clear (white) CZ stones, ranging in shape and size from 1.5 to about 5mm.
The cubic zirconia selection of shapes and sizes will differ from pack to pack.
Did you know: Cubic zirconia (or CZ), is the cubic crystalline form of zirconium dioxide (ZrO2). The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO4). Because of its low cost, durability, and close visual likeness to diamond, synthetic cubic zirconia has remained the most gemologically and economically important competitor for diamonds since 1976.
Amazing glittering sparkles
I haven't fired any yet, but a nice mix of sizes and good quality.
