5.10 Ct. Yellowish Green Prasiolite from Brazil

This prasiolite is a transparent, round faceted gemstone, weighing 5.10 carats, with precise measurements of 11.02 x 11.04 x 7.71 millimeters, presented by The Natural Gemstone Company. The cutting style is faceted with a mixed brilliant cut, executed to emphasize both depth and table scintillation, and finished with an excellent polish. The body color is a yellowish green of medium intensity, and the stone has been heat treated, a stable and commonly applied enhancement to achieve the current tone. Clarity is graded very very slightly included as evaluated at eye level, indicating that the stone presents a clean appearance to the naked eye, with any inclusions minimal and not affecting overall transparency or light performance. The gem is sourced from Brazil, a well established origin for prasiolite material, and the combination of origin, treatment, cut, and finish yields a gem of consistent, reliable visual character.

The size and clarity of this prasiolite make it particularly suitable as a statement piece, the 11 millimeter face up dimension and 5.10 carat weight affording a bold presence when set in jewelry. At this scale, the stone reads clearly from a distance, while the very very slight inclusions remain inconspicuous at typical viewing distances, allowing uninterrupted visual impact. The mixed brilliant cut enhances return of light from the pavilion and disperses light through the crown facets, producing an appealing balance of brilliance and fire for a quartz variety. The excellent polish contributes to a smooth, reflective surface that maximizes brilliance and softens facet junctions, important characteristics for a center stone intended to draw attention. For designers and clients seeking a single focal element, this prasiolite functions well in solitaire ring settings, halo compositions that amplify perceived size, pendant designs where the stone can be displayed table up, and bespoke pieces that combine metalwork and architectural settings to frame the gem without obscuring its optical properties.

From a practical standpoint, prasiolite, as a green variety of quartz, offers a Mohs hardness of approximately 7, providing satisfactory resistance to abrasion for jewelry intended for frequent wear, when set and cared for appropriately. Heat treatment applied to this specimen is permanent under normal wear conditions, and there are no indications of additional enhancements. The very very slight inclusions observed give the gem a natural character without compromising the clean face up appearance that is desirable in statement gems. When commissioning a setting, consideration of secure bezel or prong architecture will protect the girdle and pavilion, while open gallery styles will maximize light flow and display. Routine care includes avoiding prolonged exposure to high heat and harsh chemicals, cleaning with warm water, mild detergent and a soft brush, and professional inspection of the setting at periodic intervals. The Natural Gemstone Company can provide additional information on custom mounting options, current availability, and independent certification upon request, and we document origin, weight, dimensions, cut grade and clarity observations to support transparency and informed decision making. In summary, this 5.10 carat, round, yellowish green prasiolite combines notable size, excellent polish and very very slight inclusion clarity, qualities that collectively make it an excellent candidate for a distinguished statement piece.
