5.65 Ct. Cabochon Tanzanite from Tanzania

This exquisite violet tanzanite from Tanzania, offered by The Natural Gemstone Company, presents a distinct kind of brilliance that sets it apart from more common gemstones. At 5.65 carats with generous dimensions of 11.22 by 8.64 by 6.47 millimeters, the oval cabochon cut emphasizes a soft, internal luminosity rather than the sharp sparkle of faceted stones, creating a velvety glow that captures the eye. Unlike diamonds, which rely on faceted brilliance and a high refractive index to produce flashes of white light, this tanzanite displays a luminous depth and color saturation that reads as intense and alive in different light conditions. Compared to amethyst, which often appears flatter in tone at similar sizes, this piece shows richer, more complex violet hues and a translucency that allows light to travel and diffuse through the body of the gem, producing a gentle inner radiance. The slightly included clarity graded at eye level is well suited to a cabochon, where natural inclusions can add character without detracting from the stones overall glow, and the excellent polish amplifies surface reflection and tactile smoothness.

In practical terms this tanzanite offers a compelling balance of rarity, color intensity, and value, especially when measured against blue sapphires and other popular alternatives. While faceted sapphires may be harder and display sharper brilliance, they rarely capture the same violet-specific depth and pleochroic shift that makes tanzanite so visually intriguing, and high quality sapphires at this weight and hue often command a premium that outstrips the unique personality of a tanzanite cabochon. The heat treatment used here is a standard enhancement that stabilizes and intensifies the true violet color, ensuring consistency and longevity, and the Tanzanian origin confirms provenance from the only place in the world where genuine tanzanite forms. For designers and collectors seeking a standout center stone that reads as both luxurious and uncommon, this 5.65 carat cabochon delivers a superior color story, substantial presence, and approachable value, making it an exceptional offering from The Natural Gemstone Company.
