4.43 Ct. Green Tourmaline from Afghanistan

One beautiful transparent 4.43 carat emerald cut green tourmaline from Afghanistan, offered by The Natural Gemstone Company, presents a rare combination of size, clarity, and color. The stone measures 10.94 by 7.15 by 6.26 millimeters, it is emerald cut to emphasize the depth and hue of the green, it grades as eye clean at normal viewing distance, it shows medium color intensity, it carries an excellent polish, and it has been heat treated to stabilize and enhance the tone. Compared with emeralds, which often command higher prices but typically show prominent inclusions and frequent oiling, this Afghan tourmaline offers superior visual purity without the common need for filling, delivering a cleaner window and a more consistent face up appearance. Compared with green sapphires, which score higher on hardness but can be rarer in attractive transparent sizes at comparable prices, this tourmaline offers an excellent balance of attractive color and economical access to a sizable gem that retains strong presence in a ring or pendant. Against peridot, which tends to show a yellowish overtone and sits lower on the market value scale, this piece stands out for its richer green and finer clarity, making it a more versatile choice for classic and modern jewelry designs.

On the Mohs scale, tourmaline ranks at seven to seven point five, which places this gem above softer green stones such as peridot, and close to many quartz varieties, yet below corundum based gems like sapphire that measure nine. This hardness makes the tourmaline durable enough for everyday wear when set thoughtfully, and combined with its emerald cut and excellent polish it resists surface abrasion while reflecting clean step facet flashes. To maximize longevity for daily rings, a protective setting such as a bezel or well constructed prong design is recommended, especially since the emerald cut presents broad, flat facets that highlight clarity and color, but can show edge wear if exposed to repeated knocks. Heat treatment in this gem is a stable enhancement commonly accepted in the trade, and because the stone is eye clean and well cut, the treatment yields a lively, evenly saturated green without masking natural beauty. At The Natural Gemstone Company we emphasize ethical sourcing and accurate descriptions, and this Afghan tourmaline represents a compelling value proposition for collectors and designers alike, offering striking size, excellent clarity, dependable durability, and exceptional face up appeal compared with other green gemstones on the market.
