The handmade Essential Gems collection features beads carved out of lava rock, porous enough to act as natural diffusers. These lava rocks are paired with a variety of semi-precious gemstones to enhance the well being properties of the gemstones. Lava stone is known to ground the root chakra and boost the qualities of other stones. All bracelets come with a sample of corresponding essential oil along with a tumbled gemstone. All bracelets incorporate 8mm beads and are strung with highquality stretch cord. The nine Essential Gems bracelets come in sizes, 7-7.5” and 8”. See here for sizes on bracelets.
