2.18 Ct. Green Prasiolite from Brazil

This prasiolite is a precisely crafted 2.18 carat oval, measuring 10.13 x 7.99 x 5.35 mm, with a well judged depth that works out to approximately fifty nine percent of the average girdle span, a proportion that balances face up size with optimal light return. The shape is a classical oval with a mixed brilliant faceting scheme, combining a brilliant style crown and a pavilion faceting arrangement that has been configured to maximize scintillation and central flash while preserving clean outline symmetry. The mixed brilliant cut in this piece produces a pattern of large crown facets interleaved with smaller star and kite facets, which translates into strong facet contrast and lively scintillation at everyday viewing distances. The cutter preserved the oval length to width ratio to retain the gem like proportions that suit both solitaire and halo settings, and the table size was controlled to favor return rather than dispersion. The excellent polish achieved through a multi stage lapidary process produces crisp facet junctions and mirror like facet planes, which enhance face up brilliance and ensure that light paths are minimally obstructed by surface irregularities.

Color and clarity are presented with measured restraint, the prasiolite showing a light green color intensity that reads as fresh and elegant under standard daylight balanced lighting. Originating from Brazil, this material exhibits the typical, soft green tones prized in prasiolite without the yellow cast that can reduce desirability. The color is the result of controlled heat treatment applied to natural quartz, a process that transforms precursor iron related color centers into the green hue, and that is disclosed here in full. The treatment is permanent under normal wearing conditions and the piece was processed to a color stability standard expected for quality prasiolite, but as with all heated gemstones extended exposure to extreme heat or direct, intense ultraviolet light should be avoided to preserve the delicate light green tone. Clarity is graded as very slightly included when evaluated at eye level, with small internal growth related features that are effectively masked by the mixed brilliant faceting so that they do not interrupt the visual performance or the perceived clean appearance of the table.

From the standpoint of durability this prasiolite is exceptionally well suited to daily wear when properly set, based on the inherent material properties of quartz and the specific cutting decisions applied to this parcel. Quartz rates seven on the Mohs hardness scale, providing good resistance to everyday abrasion from materials softer than corundum and diamond, yet care should be taken to avoid contact with harder substances or coarse abrasive surfaces. Quartz does not exhibit easy cleavage, which reduces the risk of splitting under impact, but it does have conchoidal fracture characteristics that make edge protection advisable in jewelry design. The very slightly included clarity grade indicates that inclusions are minor and do not create significant stress concentration points, and the moderate depth and robust girdle proportions on this oval further reduce the likelihood of mechanical damage when the gem is secured in an appropriate mounting. For rings intended for daily wear we recommend either a full bezel setting or a low profile four or six prong setting with substantial metal protection at the girdle, and for pendants and earrings standard prong or bezel constructions are fully appropriate. Routine care is straightforward, comprising warm soapy water and a soft brush to remove oils and surface debris, avoiding prolonged exposure to steam cleaning and thermal shock, and having mounted pieces inspected periodically by a qualified jeweler to ensure prong security and overall fit.

The provenance and craftsmanship of this stone are consistent with The Natural Gemstone Company standards for material selection and lapidary execution, and the piece represents a balance of aesthetic refinement and practical wearability that appeals to technically minded buyers. The cutting sequence began with precise preforming to preserve rough yield while establishing the oval outline, followed by progressive faceting with exacting angle control to produce the intended mixed brilliant optical behavior, and concluded with a graded polishing regime that eliminated micro abrasion and produced the excellent polish grade reported. The heat treatment was applied in a controlled furnace environment to achieve the target green state while minimizing color zoning and maintaining structural integrity. For designers and clients seeking a versatile center stone this prasiolite offers dependable performance in a range of settings from classic solitaire rings to three stone compositions and fine pendants, and its restrained light green tone pairs well with both warm and cool metal choices. As with all gemstones supplied by The Natural Gemstone Company this item is documented with its weight, dimensions, cut description, clarity and enhancement disclosure, enabling confident pairing with mounting specifications and insurance documentation.
