Emerald Beads
Emerald beads are green beryl, colored by chromium and vanadium, cut from crystal that is too included for faceted gems but shows the same color. Fine emerald is among the most valued of gems, and bead emerald is its everyday relative. This collection holds natural emerald in a range of finishes and shapes for bracelets, necklaces and earrings.
Appearance
The green runs from a soft, slightly bluish mint to a mid grass green, lighter and less even than the saturated color of a fine cut stone, and most beads carry visible inclusions, veils and darker patches that the trade calls the garden. Strands often mix lighter and deeper beads. Differences in clarity from bead to bead is simply the crystal as it grew.
A faceted cut brightens the pale green and hides inclusions behind sparkle; polished rounds show the body color and the garden more plainly, and some makers prefer that look. At 7.5 to 8 on the Mohs scale, emerald is harder than quartz, but the inclusions make it more brittle than its hardness suggests. It wears well in necklaces and earrings; for bracelets, avoid knocks against hard surfaces and skip ultrasonic cleaners.
Formation and origin
Beryl needs beryllium, a rare element, and emerald also needs chromium or vanadium, which normally occur in very different rocks. Emerald forms where those sources meet: in Colombia, in veins through black shale opened by hot brines; elsewhere, where beryllium-rich pegmatite fluids cross chromium-bearing schists. Colombia remains the benchmark, and Zambia, Brazil, Ethiopia and Zimbabwe supply much of the bead material.
Pairings
Sapphire beads: blue corundum and green beryl, both hard and both cut small, is a classic fine-jewelry pairing.
Ruby beads: emerald's green and ruby's red share chromium coloring, and both are hard enough for daily wear.
Tanzanite beads: violet-blue next to emerald green keeps both colors clear; tanzanite is softer, so give it the lighter duty.
Meaning and Metaphysical Beliefs
Emerald has long been a stone of rulers. The Egyptian mines near the Red Sea supplied the ancient world, the Inca and Aztec valued it, and it is the birthstone for May. In crystal traditions it is associated with love, loyalty and renewal, and it is the usual green stone for the heart chakra. These are traditional beliefs, not claims of physical effect.
