4.93 Ct. Bluish Green Prasiolite from Brazil

This 4.93 carat oval bluish green prasiolite from Brazil is a finely finished and collectible gem, presented by The Natural Gemstone Company. The stone measures 12.31 x 10.04 x 6.99 mm, and is faceted in a mixed brilliant cut that balances table brilliance with scintillation from the pavilion facets. Clarity is graded as eye clean, evaluated at eye level, which means no inclusions are visible to the unaided eye and the gem presents an uncluttered field of color and light. Color intensity is described as intense, producing a saturated bluish green tone that is attractive under both natural and artificial lighting. The polish is excellent, resulting in crisp facet junctions and strong light return. The prasiolite has been heat treated, a standard and stable enhancement for this variety of quartz that improves color uniformity and depth without materially affecting durability when treated properly.

From a durability and practical wear standpoint, prasiolite ranks at 7 on the Mohs hardness scale, the same hardness as quartz. This makes it significantly more scratch resistant than common softer gems such as opal or tanzanite, and less susceptible to abrasive wear in everyday jewelry. Compared to harder gems, prasiolite is softer than sapphire which is 9 and diamond which is 10, and slightly softer than topaz which is 8, so protective setting choices and reasonable care are recommended for rings or bracelets that receive heavy contact. The combination of a 7 Mohs hardness, eye clean clarity, and excellent polish makes this gem well suited for pendants, earrings, and rings when set in designs that shield the girdle and corners. For the educated buyer this piece offers tangible value arising from its size near 5 carats, its intense and even color, and its Brazilian origin, which is known for producing high quality prasiolite material. At The Natural Gemstone Company we describe these attributes candidly to support confident purchasing decisions, and we provide guidance on setting and care to preserve the beauty and integrity of your prasiolite for years to come.
