Fluorite is renowned for its kaleidoscopic of colors, ranging from saturated hues to pastel tones. It is believed to refocus the mind by eliminating distractions and promoting mental clarity. Further purported benefits include the absorption of negative energy, the reduction of stress levels, the enhancement of self-confidence, improved cognitive performance, and more accurate decision-making. This necklace is handmade with a natural, smooth polished fluorite crystal in your choice of color. The chain and clasp are sterling silver or 14k gold filled. Fluorite is a mineral, not a stone. Therefore, it can be fragile and should be worn with care. Please do not wear fluorite while exercising, sleeping, or bathing (it is mildly water-soluble if left in water too long) and be mindful not to drop it on hard surfaces.GEMSTONE: Natural FluoriteSTONE SIZE: average 15x10mm (.59 x .39")STONE SHAPE: Smooth TeardropMETAL: 14k Gold Filled or Sterling Silver MODELED LENGTH: 16 inches
