Yellow Jasper Tumbled Gemstone

Safe to handle. No known toxicity or special precautions.

Yellow Jasper is a variety of jasper, an opaque, microcrystalline form of quartz colored gold to ochre by iron oxide impurities. It has been carved and worn since antiquity — jasper amulets appear in Egyptian, Mesopotamian, and Roman archaeological finds — with the yellow variety prized for its sunlit warmth. Modern material comes from a wide range of deposits worldwide, with no single source dominating the trade.

Yellow Jasper is a cryptocrystalline variety of quartz (chalcedony), SiO2, colored by iron oxide inclusions distributed through the silica matrix. It forms from silica-rich sediment, volcanic ash, or groundwater deposition, often in bands or nodules. Hardness runs 6.5 to 7 on the Mohs scale, and its opacity distinguishes it from more transparent quartz varieties.

• Ancient Egyptians carved scarab amulets from yellow and golden jasper, associating the sun-toned stone with solar deities and the protective power of light.
• Yellow jasper is traditionally counted among the gemstones historically linked to ancient breastplate and amulet lore, long associated with protection and favor.
• Roman soldiers reportedly carried jasper amulets into battle, trusting the stone's warm color to channel protective solar energy and steady their resolve.
