Under direct light the hue of this tanzanite reads as a violetish blue, a tone that is richer and more violet leaning than classic Ceylon sapphires, Ceylon material is often bright and pure blue with a slightly lighter, more electric tone, whereas this tanzanite leans into violet to create a deeper, more velvety appearance. Compared to Kashmir sapphires, which are legendary for their cornflower blue with a soft velvety tone, this tanzanite reveals a cooler violet overlay that produces an altogether different emotional effect, Kashmir stones feel like a painterly sky at dusk, while this tanzanite feels like twilight distilled into a single crystal. When placed beside Burmese sapphires, which can present as a saturated royal blue, the violetish blue of this tanzanite adds a floral, almost amethyst like nuance, the result is a color experience that reads as both jewel like and floral at once, the trichroic nature of tanzanite provides a subtle depth that is distinct from the more monochromatic sapphires of other famed locations.

Stylistically this 4.02 carat cushion tanzanite invites bespoke settings that honor its rarity, because the tone is so intense and the clarity eye clean, a minimalist solitaire in warm rose gold will accentuate the violet facets, while a halo of fine white diamonds set in platinum will raise the perceived size and lend a classical, museum quality presence, for an heirloom commission consider an east west mount or a low profile bezel that allows the mixed brilliant cut to catch light from every angle, pairing this Tanzanian tanzanite with step cut diamonds will highlight the gem like quality of its hue, when set with Ceylon or Sri Lankan sapphires as accent stones the contrast will emphasize the violet leaning nature of the tanzanite, when set with a single Kashmir sapphire accent the two stones will form a conversation between velvety blue and violetish blue, collectors will appreciate that stones of this size and intensity seldom appear on the market, our clients who commission bespoke pieces through The Natural Gemstone Company often request custom designs that are both wearable and museum worthy.
