5.14 Ct. Purple Amethyst from Brazil

This cushion shape amethyst weighs 5.14 carats and measures 11.75 x 8.09 x 7.30 mm. The gem is transparent and precisely faceted in a mixed brilliant cut that balances scintillation with color depth. The color presents as a vivid saturated purple, consistent across the table and pavilion facets, and the polish has been evaluated as excellent, producing crisp facet junctions and lively light return. Clarity is graded as very very slightly included, evaluated at eye level, with only minute natural features that do not detract from the face up appearance or the overall transparency. There has been no enhancement to this material, and provenance is Brazil, a well established source for high quality amethyst. The Natural Gemstone Company stands behind these observations and offers this description to support informed selection and design planning.

From a structural and durability perspective this amethyst is a variety of quartz and rates seven on the Mohs hardness scale. In practical terms this places the stone below diamond at ten, and below corundum at nine, and topaz at eight, and above many common gem materials and organic gem substitutes. A Mohs seven rating affords good resistance to everyday abrasion yet does mean that the stone can be scratched by harder materials and may show wear if rubbed repeatedly against surfaces containing corundum or diamond grit. Quartz exhibits no true cleavage and typically shows conchoidal fracture, so while it is not prone to splitting from gentle pressure it will be vulnerable to sharp impacts. The mixed brilliant cut and the nearly eight millimeter depth produce strong internal reflections and a robust pavilion that aids durability, provided the mounting protects the girdle and corners. For jewelry intended for frequent use such as rings, a protective setting is advisable, and for pendants and earrings the stone offers comfortable durability while retaining excellent optical performance.

Care recommendations reflect the stone chemistry and the absence of enhancements. Routine cleaning with warm soapy water and a soft brush will maintain brilliance and remove oils and surface residues. Ultrasonic cleaning is generally acceptable for most natural amethyst material, though any treatment history and the presence of internal inclusions should be considered prior to use of mechanical cleaning methods. Prolonged exposure to intense heat or strong fading light can affect color saturation over long time frames, so avoid extended direct sunlight and high temperature conditions when possible. Harsh chemical agents such as strong acids and household bleach should be avoided. For settings where the stone may be subject to knocks or abrasion, consider bezel or partially bezel mounted designs that protect the girdle and corners, and specify secure prong work where necessary to reduce risk of impact damage. This 5.14 carat Brazilian cushion amethyst from The Natural Gemstone Company combines vivid color, excellent polish, and a clarity grade evaluated at eye level, with the practical durability of a Mohs seven material, making it a suitable choice for thoughtful jewelry design that balances visual appeal with everyday wear considerations.
