Crushed Calcite Coarse Sand - Natural Gemstone

Calcite is one of the most abundant minerals on earth - the primary mineral in limestone and marble. Our coarse-grind calcite sand delivers a clean white/off-white color with visible crystalline particles, making it one of the most versatile neutral-toned gemstone powders in the catalog.

For Jewelry Makers & Crafters

Coarse calcite sand creates a clean, bright contrast in clear resin - ideal for pieces where a bright white or light neutral base is the goal. Use it in resin casting, bezels, mosaic work, and mixed-media art. Its neutral white tone makes it easy to pair with colored powders for layered and gradient effects.

For Wood Inlay Artists

The coarse grind packs cleanly into routed grooves and creates a sharp white-on-wood contrast once set with epoxy and finished. Works particularly well against dark wood species like walnut and ebony for a striking light/dark contrast.

For Orgonite & Energy Art

White calcite is used as a bright, light-reflecting layer in orgonite pyramids and energy sculptures. Its clean white color creates strong visual contrast when layered with dark or metallic materials.
