Crushed Quartz + Tourmaline Sand from China, Three Sand Sizes for Woodworking and Ring Inlay, Resin Art, Memorial & Sand Jewelry

Quartz and tourmaline are two minerals that commonly crystallize together during late-stage magmatic processes, especially in pegmatites and hydrothermal veins where mineral-rich fluids allow both to form side by side. This crushed material features an even blend of clear quartz, smoky quartz, and black tourmaline, giving it a balanced mix of color and texture. The material is clean and well blended, making it suitable for a variety of uses, and is offered in three different sand sizes to accommodate different applications.

MATERIAL SIZE

Our crushed sand-sized material ranges from very fine to coarse sand, and is available in three different size variations: 1mm to 2mm (coarse sand), 0.25mm to 2mm (medium sand), and 0.25mm to 1mm (fine sand). Our sand-sized material is ideal for a wide range of creative projects, including woodworking inlays, memorial and resin jewelry, orgonite pyramids, ring inlay, resin molds, mosaics, terrariums, bezel cups, resin art, embellishments, and metaphysical projects.

EXTRA LISTING INFO

We prioritize providing high-quality materials for all artisans; therefore, our stones are natural and untreated unless otherwise specified. Photos may showcase both wet and dry crushed stone. Please note that wet stones can appear darker, which may resemble the finished look of the material after it's sealed with an adhesive.

We use the metric system for all size measurements, with units in millimeters (mm). Refer to the product photos for a visual guide using a metric ruler (cm/mm).
