21.69 Ct. Tourmaline from Brazil

One beautiful transparent 21.69 carat emerald cut shape green tourmaline is an exceptional example of what discerning collectors and investors seek. This gem measures 19.91 x 13.47 x 8.54 mm, and its elongated emerald cut offers strong symmetry and faceting that maximizes the gem clarity and color saturation. The stone is graded as very very slightly included evaluated at eye level, a clarity that is rare in such a large green tourmaline, and its vivid color intensity gives it a lively, saturated green that reads with presence, even when viewed from a distance. The polish is excellent, producing clean, crisp facet junctions and a mirror like surface that enhances light return and overall brilliance. The gemstone is heat treated, a standard and stable enhancement practice for tourmaline that optimizes hue and tone without compromising structural integrity. Originating in Brazil, a source known for fine tourmaline material, this stone carries the geological provenance that collectors value. The Natural Gemstone Company presents this piece as a singular opportunity for those who appreciate the combination of size, clarity, cut, and color in a green tourmaline.

When comparing this green tourmaline to other gemstones on the market, its advantages become clear. Compared to emeralds of similar color, this tourmaline offers superior transparency and a higher clarity profile, since emeralds often display extensive inclusions and require oiling or more invasive filling treatments to improve clarity. Against green sapphires and tsavorites, this tourmaline stands out for its large carat weight combined with vivid saturation, a pairing that is very uncommon for many other green gems at this scale. Even within the tourmaline family, stones over 20 carats with a clean appearance and vivid color are scarce, making this piece particularly desirable. The emerald cut further differentiates it from the more common oval or cushion cuts, providing an elegant, architectural aesthetic that suits both classic and contemporary jewelry designs. The heat treatment involved is modest in comparison to the extensive enhancements applied to many other green stones, and the excellent polish achieved by skilled lapidary work ensures the gem will perform exceptionally in either a museum quality setting or as the centerpiece of a bespoke commission.

From an investment perspective, this green tourmaline offers several attributes that support potential future appreciation in value. Quality factors such as substantial carat weight, notable transparency, a vivid and evenly distributed color, and a precise emerald cut all contribute to intrinsic value, and these criteria are the ones that serious collectors and specialized buyers consider first at auction and in private sales. The supply of large, fine quality green tourmalines from reputable origins such as Brazil is limited, and as accessible sources become more constrained, scarcity will tend to support upward pressure on prices for the best material. Market demand for colored gemstones as alternative assets has increased, driven by collectors seeking tangible stores of value that are portable, durable, and aesthetically rewarding. Unlike heavily treated stones that face skepticism in high end markets, a well proportioned tourmaline with only heat treatment maintains strong appeal. Additionally, the unique combination of carat weight and clarity in this piece positions it well for interest from both collectors and designers, increasing its liquidity in the niche market for investment grade colored gems.

Choosing this green tourmaline from The Natural Gemstone Company means selecting a gem that is superior in terms of value proposition and long term desirability. The gem is versatile enough to be set into an important ring, a statement pendant, or retained as an investment piece in secure storage, and its classic emerald cut ensures that the value will translate across different styles and eras. Compared to more common or heavily treated alternatives, this tourmaline offers a cleaner, more honest representation of natural beauty paired with a sensible enhancement that improves appearance without compromising permanence. For buyers focused on future appreciation, a stone of this caliber and provenance offers a compelling blend of rarity and market appeal. Our team at The Natural Gemstone Company can assist with documentation, careful handling recommendations, and guidance on display or setting options to preserve condition and maximize long term value. We invite serious collectors and jewelry connoisseurs to consider this green tourmaline as a strategic addition to a gemstone portfolio, a wearable investment, and a piece of natural art that will be enjoyed for generations.
