Chrome Diopside Beads
Chrome diopside beads are a calcium magnesium silicate colored a deep green by traces of chromium, the same element that colors emerald. Nearly all gem material comes from a single district in eastern Siberia. This collection holds natural chrome diopside, including strands with a white calcite matrix, in a range of finishes and shapes for bracelets, necklaces and earrings.
Appearance
The green is rich and slightly yellowish, close to emerald in hue, and it deepens quickly as the stone gets thicker, so the color varies from bead to bead within a strand and darker beads can look nearly black at the center. Most material is transparent to translucent with small inclusions. Chrome diopside with calcite matrix pairs the green with white, where the diopside crystals sit in the pale carbonate rock they grew in.
Faceting suits the stone, since it breaks the dark body color into bright green flashes; polished rounds show a quieter, glassier green. At 5.5 to 6.5 on the Mohs scale, chrome diopside is softer than quartz and has two directions of cleavage, so it can chip or scratch more easily than most bead stones. Save it for necklaces and earrings, or for bracelets that are not worn daily, and store it apart from harder beads.
Formation and origin
Diopside is a pyroxene, a mineral that crystallizes in magma and in metamorphosed limestone. The chromium-rich variety forms in magnesium-rich rocks from the mantle, dunite and peridotite above all, and it also turns up in kimberlite, the rock that carries diamond; chromium from those rocks enters the diopside structure and gives it the green. The main source is the Inagli deposit in the Sakha Republic of Russia, a dunite body mined for gem material since the 1980s; smaller amounts come from Pakistan, Kenya and Finland. Chrome diopside is sometimes sold as Siberian emerald or Russian diopside, which is the same stone under another name.
Pairings
Ruby beads: red and green from the same chromium coloring sit well together, and both are usually faceted small.
Spinel beads: black spinel between green diopside gives contrast, with the harder stone taking the wear.
Green apatite beads: a lighter, bluer green next to diopside's forest green, and the two are close in hardness.
Meaning and Metaphysical Beliefs
Chrome diopside has little ancient lore, since it reached the gem market only in the 1980s. In modern crystal traditions it is associated with growth, learning and a connection to the natural world, and its green has linked it with the heart chakra. Some writers describe it as a stone of creativity and commitment. These are traditional beliefs, not claims of physical effect.
