1.17 Ct. Violetish Blue Tanzanite from Tanzania

Beneath the sun baked plateaus of northern Tanzania, in the famous Merelani Hills that yield the world famous tanzanite, a story older than human hands wrote itself in stone. Deep within metamorphic rock, under great heat and pressure, zoisite crystals gathered trace elements that would one day become this violetish blue tanzanite. The rarity of this geological recipe is part of the gem value, because tanzanite is found in only one small region on Earth, and each crystal that survives the rise to the surface carries a record of those ancient forces. When you hold this stone you are holding a fragment of that deep time, a color forged by nature in a place that is as singular as the gem itself. That origin, the Merelani Hills, is more than a label, it is a provenance that speaks to scarcity, to authenticity, and to a connection between land and light that elevates the stone beyond simple ornament.

This particular specimen is a transparent, 1.17 carat, round shape tanzanite with refined dimensions of 6.52 by 6.50 by 4.57 millimeters, faceted in a mixed brilliant cut to maximize scintillation and depth. The hue is a vivid violetish blue with intense color intensity, a tone that reads both regal and modern, and that plays beautifully with light because of the stone natural trichroic character. When tilted and turned the gem will favor different color facets, revealing violet, deep blue, and warmer blue violet flashes, a subtle show that is part of what makes tanzanite so enchanting. Clarity is graded as very very slightly included evaluated at eye level, which means the gem appears clean and lively to the view without magnification, while still retaining the small internal signatures that confirm its natural origin. The polish is excellent, so every facet edge rings with crisp reflection, and the overall result is a gem that balances brilliance, color, and natural character.

The path from rough crystal to this 1.17 carat round gem is a dialogue between human skill and natural form. Skilled cutters observed the internal structure and natural color zoning, and chose a mixed brilliant style to both preserve weight and to coax maximum fire from the stone. The crown facets were cut to invite bright white reflection, while pavilion facets were tuned to return rich blue and violet flashes, making the most of the 6.52 by 6.50 by 4.57 millimeter proportions. Heat treatment was applied to gently enhance the blue violet tone, a traditional and stable practice that reveals the stone inherent color potential without altering its natural identity. The result is a gem that sits beautifully in the hand and that will sit beautifully in a custom setting, ideal for a solitaire ring where the round silhouette centers attention, or for a pendant where light can pass through and awaken those trichroic nuances. Pairing this violetish blue tanzanite with white metals such as white gold or platinum will intensify the cool blue, while warmer metals will draw out the softer violet notes, giving you design latitude that makes this gem versatile and enduring.
