1.79 Ct. Tanzanite from Tanzania

There are gemstones that are acquired, and then there are gemstones that are appointed to become heirlooms, selected by collectors who recognize the confluence of rarity, provenance, and superior craftsmanship. This is one such stone, offered exclusively by The Natural Gemstone Company. We present a beautiful transparent 1.79 carat oval shape blue tanzanite, whose dimensions of 8.98 x 6.84 x 4.22 mm place it in a class of stones that are immediate statements of refined taste. The color is intense, a saturated blue that commands attention while remaining supremely elegant, and the clarity is eye clean when evaluated at eye level, ensuring that the gem reads as pure and vivid to the unaided eye. The polish is excellent, an indicator of careful lapidary finishing that gives each facet the precision needed to deliver unfettered brilliance. This tanzanite has been responsibly heat treated, a standard and disclosed enhancement that deepens its blue character, and it is sourced from Tanzania, the only place on earth where tanzanite forms, reinforcing its inherent rarity. For the discerning collector or the client seeking a singular gift, this tanzanite is a private opportunity to possess a gem that is both naturally rare and personally distinguished.

The mixed brilliant cut of this oval tanzanite is central to how the stone performs under light, and it is the reason this gem feels alive from every angle. A mixed brilliant cut combines the scintillation and fire of brilliant faceting with the larger, graceful planes of step cutting, creating a hybrid that leverages the best qualities of both approaches. In this oval, the crown facets are arranged to catch and break incoming light into lively flashes, while the pavilion facets are angled to return that light directly back to the eye, maximizing brilliance. The elongated oval outline increases the perceived size compared with a round stone of the same carat weight, and the symmetry of its proportions ensures that light flows evenly across the surface, avoiding dead zones or dark windows. Tanzanite displays pleochroism, a trait that shows different hues at different angles, and the mixed brilliant design plays to this feature by allowing flashes of deep blue and subtle violet to alternate as the stone moves, creating a theatrical interplay that is both sophisticated and mesmerizing. The specific depth of 4.22 mm relative to the length and width has been balanced to avoid an overly deep pavilion, so light is not lost but returned, and the excellent polish ensures every facet edge is crisp and reflective, contributing to an overall impression of heightened luminosity and refined sparkle.

Owning this tanzanite places you among a select group who appreciate the intersection of natural origin, careful enhancement, and masterful cutting. At The Natural Gemstone Company we curate gemstones like this one not as commodities but as bespoke treasures that belong in settings designed to celebrate their individuality. Imagine the stone set as the centerpiece of a custom ring with a slender platinum shank to emphasize color purity, or as a low profile pendant in warm 18 karat rose gold to bring out the stone s violet undertones, or surrounded by a halo of fine white diamonds to increase perceived size while adding a luminous contrast. Each mounting choice will further activate the mixed brilliant cut, allowing the tanzanite to communicate differently in daylight and evening light. Because this stone is transparent and eye clean, it adapts effortlessly to open prong settings that reveal the pavilion work, or to bezel settings that emphasize shape and silhouette for a more architectural statement. We offer private consultations and bespoke design services to ensure the final jewelry piece reflects your personal narrative, and because such premium tanzanites are uncommon, we limit our offerings so that each client receives a level of attention and exclusivity commensurate with the beauty of the gem.

We stand behind this gem with full disclosure and attentive service, and we welcome inquiries for private viewing, certification details, and bespoke mounting options. The 1.79 carat weight, the exact measurements of 8.98 x 6.84 x 4.22 mm, the mixed brilliant cut, the eye clean clarity at eye level, the intense color intensity, the excellent polish, the heat treatment, and the Tanzanian origin are all facts we present transparently, because provenance and treatment matter to serious collectors. Care for this tanzanite is straightforward, with gentle cleaning recommended, and careful storage to avoid hard knocks that could chip the well defined facet edges.
