Four faceted flat round peridot beads, to add a gemstone to a creation in small touches. Their olive green, bright and clear, is enough to brighten a pair of earrings or a ring. Features: Stone: natural peridot Shape: faceted flat round Size: approximately 3.5 to 4 mm in diameter Thickness: approximately 2.5 mm Quantity: lot of 4 beads Color: olive green Mount them one by one on a pin or on thin thread: as an earring drop, as the central bead of a ring, as an accent on a gold chain or to complete a strand of seed beads. For a larger project, the full thread of approximately 100 beads is also available. A bit of gemology: peridot is the jewelry name for gem-quality olivine, an iron and magnesium silicate that is among the most abundant minerals in the Earth's mantle, but rarely clear enough to be cut. Its hue comes from the iron in its structure: the more there is, the deeper the green shifts toward olive; it is an intrinsic color, which the stone does not lose and which is not treated. Hardness of 6.5 to 7 on the Mohs scale, density of approximately 3.3: a little heavier in the hand than a quartz of the same size. The origin of the word remains debated; it is often linked to the Arabic faridat, "precious stone". To know: avoid acidic products and thermal shocks; a soft cloth and a little warm water are enough to care for it. In lithotherapy: stone of the heart chakra, peridot is said to dispel tension and promote optimism. Worn as an amulet since Antiquity, it is attributed a protective role. 100% natural product: the size, shape and color may vary slightly from one lot to another.
