  • 【Lab-Grown Ruby Corundum Upgrade】Made from lab-grown ruby-colored corundum, offering bright color, smooth surface and reliable hardness for users who prefer a more refined material than ordinary quartz or glass beads in their projects.
  • 【No-Hole Spheres for Fine Work】Each sphere is about 2-16mm in diameter and undrilled, ideal for groove or channel inlay, bezel-style encasement, resin art, wood inlay and other detailed designs where a clean spherical surface is required.
  • 【High Hardness & Heat-Resistant Structure】Ruby corundum is known for its high hardness (around Mohs 9) and stable performance at elevated temperatures, making these spheres suitable for projects that involve repeated heating, friction or long-term handling.
  • 【For Jewelry, Crafts and High-Temperature Demonstrations】Suitable for ring and earring accents, pendants, bracelets, resin and wood projects, as well as high-temperature inlay tests, thermal demonstration models and column or media packing in small experimental setups.
  • 【Gift-Ready Set】Approximately 50 ruby spheres are packed together for easy storage and everyday use, making this set convenient for makers to keep on hand and also suitable as a thoughtful small gift for jewelry makers, craft lovers, or anyone who enjoys precise, gemstone-like details.
