Comment: We are broadening our inventory to include new, unknown or lower priced gem varieties. Welcome therfore prehnite, a translucent green-yellow gem with a most unique crystal. The only gem with a similar fluid inner life would be hessonite, and then only in its most densest forms, almost translucent. Prehnite seems to enclose a hazy fluid, its brilliancy a shimmering glaze, like sun-shine playing in a slow-moving, algea-rich river. If you honor us with the setting of these new gems we guarantee they come out secure and safe to wear (many local goldsmiths may not want to work with unknown varieties). As all our gems, this prehnite is untreated and comes with an independant lab report. Free of inclusions and without window, fulfilling our three target qualities: no treatment, no inclusions, no window ('the 3-Nos'). See the extra image below with direct sunlight shining into the body showing its internal structure and clarity. Note, too, this is a checkerboard cut, ideal for translucent gems. Our price includes, as always, lab report, free shipping, a 1000sqm rainforest, and all other Wild Fish extras.
