1.88 Ct. Bi Color (Peacock) Tanzanite from Tanzania

From the rugged foothills of Tanzania to the quiet desks of our gem cutters, this tanzanite carries a story that begins in the earth and ends as a jewel ready to inspire. Mined in a region where blue and violet light seems to be trapped in the bedrock, the rough crystal that became this stone was discovered by hands that know the land and the seasons. That initial find set a journey in motion, a chain of care that preserved the stone's natural character while revealing the best of its potential. Weighing 1.88 carats, and fashioned into a cushion shape that balances classical form with contemporary presence, this specimen measures 7.64 x 5.87 x 5.30 mm. Its bi color peacock personality shows the very thing collectors and connoisseurs prize, an interplay of blue, violet, and subtle green tones that tell you the story of changing light and varying crystal orientation. At The Natural Gemstone Company we honor that origin, and we document the Tanzanian provenance as part of the gem's identity.

The transformation from rough to refined was handled with intention. Cut as a mixed brilliant, the facets were planned to maximize scintillation while honoring the tanzanite's pleochroic nature. The cutter worked with a keen awareness of the stone's color zoning, aligning pavilion angles to coax a lively balance of face up color and internal fire. The clarity grade has been assessed as very slightly included evaluated at eye level, which means you see a clean window of color with modest inclusions that do not distract from performance. A careful heat treatment was applied, a standard and stable enhancement that harmonized the hue and removed residual brown tones, revealing a medium color intensity that sits beautifully between delicate and dramatic. The polish is excellent, giving every facet a mirror finish that allows light to travel and return with purity, improving brilliance and enhancing the tactile pleasure of this gem when set and worn.

When it comes to optical character, tanzanite tells a different tale from more common gemstones. Diamonds are famous for their fire and exceptional brilliance due to a high refractive index, and sapphires show deep saturated color and strong durability. This tanzanite does not compete by those exact measures. Instead it distinguishes itself through its trichroic nature, a quality that lets the gem shift between blue, violet, and greenish tones as it moves. That peacock bi color effect creates moments of surprise and personal connection because the stone seems to respond to the angle of light and the movement of the wearer. The mixed brilliant cut amplifies this effect by creating small flashes of light that interplay with color flashes, producing a dynamic, almost animated presence that many people find more emotionally engaging than a static single tone. Against amethyst or standard blue sapphire, this tanzanite offers a softer, more velvety glow and a more complex color story. Compared to emeralds, which boast deep, saturated greens and often significant inclusions, this gem brings clarity and scintillation with a refined, lilac violet personality that is rare and evocative.

Presented by The Natural Gemstone Company, this cushion bi color peacock tanzanite is a jewel for someone who values narrative as much as optics. It is an excellent candidate for a center stone in a ring where movement will let its colors sing, or in a brooch or pendant that can capture varied light during daily wear. Thoughtful setting choices will protect the stone while showcasing the mixed brilliant facets and superb polish, and our team can advise on mounting styles that highlight the dimensions 7.64 x 5.87 x 5.30 mm and the stone's medium color intensity. For care, avoid sudden temperature shocks and abrasive contact, and clean gently with warm water and mild soap to preserve the surface polish. This tanzanite is not only a gem to own, it is a conversation starter, a living piece of the Tanzanian landscape that changes with the light and earns attention through subtlety rather than loud sparkle. We at The Natural Gemstone Company are proud to bring this piece from its birthplace to your collection, and we welcome the opportunity to help you imagine the setting that will make this stone uniquely yours.
