This beautiful 4.05 ct Tanzanite from the Merelani Hills, Tanzania offers a classic, versatile presence in a roundish cut—perfect for designs that want a softer outline than a strict round, while still keeping a timeless look.
The gemstone shows the same attractive medium-saturated purplish-blue color as the previous tanzanite: recognizably Tanzanite, bright and lively, and easy to wear. It avoids the “too dark” look some stones can have, while still delivering enough saturation to feel rich and valuable.
A roundish outline is extremely flexible for jewelry and works beautifully in:
solitaire rings
halo designs
pendants and classic everyday pieces
modern bezels that highlight the soft outline
With 4.05 ct, this tanzanite has real presence and makes an excellent centerpiece stone—ideal for anyone looking for size, color, and wearability in one gem.
A lively Merelani Tanzanite with friendly medium purplish-blue color and a versatile roundish shape—ready for an elegant signature design.
