Description
This 1.31 ct Tanzanite from Merelani Hills, Tanzania combines a classic violet blue color with the elegant proportions of a marquise cut. Sourced from the world-famous and only known Tanzanite deposit, this gemstone offers the unique character and rarity that have made Tanzanite one of the most admired colored stones in fine jewelry.
Fine violet blue color from Merelani Hills
Tanzanite is celebrated for its captivating mix of blue and violet, a color combination that gives the gem its unmistakable identity. This stone displays a refined violet blue appearance with lively and elegant character, making it especially attractive for jewelry that is meant to stand out while remaining tasteful and wearable.
Marquise cut — elongated, elegant, and expressive
The marquise shape is known for its slender outline and pointed ends, creating a graceful and flattering look on the hand or when set into a pendant. Its elongated form often makes the stone appear larger face-up and adds a touch of sophistication to both classic and modern jewelry styles. It is particularly well suited for solitaire rings, vertical pendants, halo designs, and distinctive bespoke settings.
A versatile single stone for fine jewelry
At 1.31 ct, this Tanzanite offers a very practical and appealing size for high-quality jewelry. It has enough presence to become the centerpiece of a ring or pendant, while remaining elegant and easy to wear. Set in white gold or platinum, its cooler tones appear especially crisp and vivid, while yellow or rose gold can bring out the stone’s warmer violet nuances.
