2.20 Ct. Green Tourmaline from Tanzania

This heart shaped green tourmaline, offered by The Natural Gemstone Company, is a superb choice for an engagement gem because it combines classic symbolism with strong gemological credentials. The stone weighs 2.20 carats and measures 7.14 x 8.51 x 6.46 millimeters, presenting as a substantial and elegant heart that reads beautifully on the finger. It is fashioned as a mixed brilliant cut, which balances the depth and pavilion facets typical of brilliant cutting with a well executed girdle and crown geometry to maximize return of light. The color is described as medium intensity green, a hue that reads fresh and vivid without being overly dark, and the polish has been graded excellent, giving the surface a lively and reflective finish. Clarity is very very slightly included, evaluated at eye level, which means the gem is essentially eye clean and any inclusions are minor and require magnification to observe. There has been no enhancement to this tourmaline, an important point for collectors and couples who prefer natural, untreated stones, and the gem is sourced from Tanzania, a region known for producing fine, well colored tourmalines.

From a gemological standpoint this green tourmaline is technically and aesthetically pleasing. Tourmaline typically has a refractive index in the neighborhood of 1.624 to 1.644, and modest birefringence which contributes to subtle doubling of facet lines when viewed at certain angles. Specific gravity for tourmaline commonly falls in the range of about 3.02 to 3.26, and the Mohs hardness is approximately 7 to 7.5, which places it well above many common jewelry minerals and suitable for regular wear when set responsibly. Tourmaline is also noted for pleochroism, the ability to show different tones of color from different viewing angles, and in this green variety you can expect lively shifts between yellow green and deeper forest tones depending on light and viewing direction. The mixed brilliant cut on this stone has been executed to accentuate brilliance and scintillation while maintaining the graceful lobes and cleft that define the heart silhouette, so you get both an emotional symbol and dependable optical performance.

When considering an engagement ring setting, this heart shaped tourmaline is exceptionally versatile and distinctive. The heart shape is inherently romantic, and at 2.20 carats it provides a visible presence without overpowering the wearer. For daily wear and long term durability select a setting that protects the most vulnerable areas of the heart, namely the cleft at the top and the pointed tip at the base. A secure prong setting with a slight V prong at the tip, or a partial bezel that covers the point while allowing the lobes to breathe, will give excellent protection while preserving sparkle. Metal choices can enhance the stone color, yellow gold will warm the green and create a classic contrast, rose gold adds an elegant vintage tone, and platinum or white gold will emphasize the stone s brilliance with a cool backdrop. Because this tourmaline is untreated and eye clean at its given clarity grade, you will be presenting a gem that tells a clear story of natural origin and careful cutting, which many educated buyers value as much as weight and color.

Caring for a tourmaline engagement piece is straightforward, and because this stone is natural and unenhanced you can expect stable long term performance with reasonable care. Routine cleaning with warm soapy water and a soft brush will maintain the polish and return the stone s internal fire. Avoid harsh chemicals and extended exposure to high heat, and while this particular stone is eye clean and carefully cut, ultrasonic or steam cleaning is best avoided unless confirmed safe for the specific setting and inclusions. At The Natural Gemstone Company we provide full disclosure on origin and treatments, and we can supply documentation and professional photographs to accompany the gem. We also offer consultation on complementary settings and bespoke design options to make this heart shaped green tourmaline into a one of a kind engagement ring. For couples seeking a meaningful, naturally beautiful, and gemologically sound alternative to traditional stones, this Tanzanian green tourmaline is an excellent, trust worthy choice that balances rarity, aesthetic appeal, and wearable strength.
