5.51 Ct. Yellowish Green Prasiolite from Madagascar

This transparent 5.51 carat oval prasiolite from Madagascar offered by The Natural Gemstone Company presents an exceptional combination of size, color, and craftsmanship, ideal for the educated buyer seeking both beauty and integrity. Measuring 12.65 by 10.42 by 7.52 mm, the gem is faceted in a mixed brilliant cut that maximizes scintillation while preserving weight and proportion. The color is an intense yellowish green that reads lively under both daylight and artificial lighting, and the excellent polish ensures crisp facet junctions and strong return of light. Clarity is graded very slightly included at eye level, a realistic and desirable grading for a gem of this size, and the stone has been heat treated, a common and accepted enhancement in prasiolite to stabilize and intensify the green tones. Origin is Madagascar, a source known for high quality quartz varieties, which contributes to provenance and collector appeal.

Inclusions within this prasiolite serve as unique identifiers that add character and provenance, rather than detracting significantly from visual performance. Under magnification you may observe fine needle like or feather patterns typical of quartz, occasional pinpoint crystals, and very small internal growth features that are consistent with natural formation and subsequent heating. These features are useful for gemological verification, they help distinguish this natural, heat treated prasiolite from synthetic alternatives, and they provide a fingerprint for future appraisal and re identification. At an eye level the very slight inclusions remain unobtrusive, often masked by the gemill s lively facets, and they can create subtle internal reflections that enhance perceived depth. For setting, the oval mixed brilliant profile is well suited to both solitaire and halo styles, allowing the gem to read larger on the finger while maintaining balance and light performance. The Natural Gemstone Company stands behind accurate disclosure of clarity, enhancement, and origin, and we include detailed imagery and measurement information so that connoisseurs and designers can assess cut proportions, color intensity, and the distinctive inclusion patterns that make this prasiolite a verifiable and attractive addition to any collection.
