1.42 Ct. Bi Color (Peacock) Tanzanite from Tanzania

This 1.42 carat cushion shape bi color peacock tanzanite from Tanzania is a superb example of precision cutting and natural color play, offered by The Natural Gemstone Company. Measuring 6.41 by 6.41 by 4.72 mm, the stone is fashioned in a mixed brilliant cut that balances a broad, elegant table with faceting designed to maximize scintillation and depth. The medium color intensity presents a refined peacock palette with shifting blue violet and greenish flashes typical of high quality Tanzanian material, and the stone has been heat treated to stabilize and enhance these desirable tones. Clarity is graded as very slightly included, evaluated at eye level, indicating that the gem is essentially eye clean for most wearers, with minor inclusions that do not interfere with brilliance. An excellent polish further refines facet junctions and surface finish, allowing this tanzanite to return light with crisp, lively sparkle and strong contrast between light and dark facets.

For the educated buyer seeking a centerpiece gem, this cushion peacock tanzanite offers both aesthetic distinction and practical considerations, making it ideal for bespoke engagement rings or collector settings. The mixed brilliant cut delivers exceptional optical performance, producing a dynamic mix of fire and scintillation that draws the eye to the heart of the stone, while the classic cushion outline lends timeless versatility for both contemporary and vintage inspired designs. Origin from Tanzania is significant, as this locality yields some of the most sought after tanzanite material, and the disclosed heat treatment is a standard, stable enhancement that deepens the blue violet spectrum without compromising integrity. Because tanzanite is more sensitive than corundum, we recommend setting designs that protect the girdle and edges and advise gentle care, avoiding harsh impacts and steam or ultrasonic cleaners. At The Natural Gemstone Company we select gems for cut quality, clarity, and color harmony, and this 1.42 carat peacock tanzanite exemplifies our commitment to offering stones that perform as striking centerpieces in fine jewelry collections.
