About the Setting:
The mounting is crafted in 14K white gold with a dramatic double halo architecture — an inner channel of baguette diamonds sits flush against the tanzanite girdle, while an outer border of round brilliant pave diamonds frames the entire face of the ring in continuous white light. The profile view reveals a cathedral-style open gallery with radiating baguette spokes and pave-set round diamond rows climbing the shoulders, creating a crown-like silhouette that elevates the center stone majestically above the finger. The wide, high-polish flat shank provides a bold, comfortable base that anchors this substantial stone with confidence.
About the Stones:
The 15.50 carat round tanzanite measures 14mm across and exhibits the signature violet-blue to deep blue pleochroism that has made tanzanite one of the most coveted colored gemstones of the modern era. Found only in a single mining area near Mount Kilimanjaro in Tanzania, tanzanite is geologically one thousand times rarer than diamond, making a stone of this carat weight exceptionally collectible. The round brilliant cut showcases the full depth of the stone's color shift — flashing between rich royal blue and warm violet depending on the light source and viewing angle. The 1.50 carats of G-H, SI1-SI2 diamonds in both baguette and round brilliant cuts provide a crisp white frame that intensifies the tanzanite's saturated hue by contrast.
