1.66 Ct. Tanzanite from Tanzania

This exquisite pear shape tanzanite from The Natural Gemstone Company weighs 1.66 carats, and measures 8.03 x 6.64 x 5.16 mm, and presents a transparent body with a mixed brilliant cut that has been carefully proportioned to balance brilliance and face up color. The clarity is graded as eye clean at typical viewing distance, which means that under normal observation no inclusions interrupt the visual impact, and the excellent polish enhances surface reflection and overall scintillation. This stone has undergone standard heat treatment to deepen and stabilize its violet hue, a widely accepted enhancement for tanzanite that converts the natural brownish tones often present in rough material to the vivid violet that collectors and designers prize. The gem is of Tanzanian origin, which is the exclusive natural source of gem quality tanzanite, and this provenance contributes both to its desirability and to its narrative value for clients who appreciate traceable supply chains.

Color is the defining attribute of this tanzanite, and its medium intense violet tone will stand out beautifully in any jewelry setting. Tanzanite is known for strong pleochroism or trichroism, showing different colors when viewed from different crystal directions, and a skilled cutter will orient the pavilion and table to maximize violet and blue flashes rather than brown. In this specimen the mixed brilliant faceting and the pear silhouette produce an even distribution of color, creating a lively play of violet flashes across the table and crown as the wearer moves. The medium intense color intensity places this stone in a category that offers a balance between saturated, collectible tones and practical everyday wearability, and the transparent body allows light to penetrate and reflect from many facets, producing depth and fire that read immediately to the eye even in modest ambient lighting.

From a gemological and design perspective the pear shape and mixed brilliant cut are particularly effective at combining perceived size with elegance. The dimensions of 8.03 x 6.64 x 5.16 mm give this tanzanite a confident face up presence that will read as larger than a more shallowly cut stone of equivalent weight, while the pointed end of the pear focuses light and draws visual attention. The mixed brilliant arrangement creates a central scintillation surrounded by smaller facet reflections, which is ideal for settings that aim to highlight both color and sparkle. The eye clean clarity ensures that the field remains free of distracting inclusions, and the excellent polish means that every facet edge is crisp, supporting maximum light return. For secure and flattering display consider a classic prong setting that allows light to enter from all angles, or a light enhancing cathedral or halo design if you wish to amplify perceived color and presence while maintaining comfort for everyday wear.

For an educated buyer this tanzanite represents a coherent value proposition, combining prized Tanzanian origin, meticulous cutting and finishing, and a stable heat treatment that enhances visual appeal without compromising integrity. The rarity of natural tanzanite deposits, concentrated in a single region of Tanzania, contributes to the long term desirability of well cut gems with fine color, and the combination of medium intense violet tone and eye clean clarity positions this gem as a versatile choice for investment quality jewelry. Care is straightforward, using warm soapy water and a soft brush for routine cleaning, avoiding abrupt temperature changes and harsh chemicals, and having professional inspections of settings periodically to ensure secure mounting.
