4 Pieces Natural Tanzanite 3.5mm 0.70ct Round Cut

Four natural tanzanite round cuts in a 3.5mm size, showing the full tonal breadth of this extraordinary gemstone in a single set. The leftmost stone has a medium blue-violet hue, the second shifts into a steely silvery-blue, the third deepens into a more teal-blue tone, and the rightmost settles into a light lavender. Fine needle inclusions are characteristic of the natural SI clarity.

These heat-treated tanzanites come from the Merelani Hills of Tanzania and are well-suited for a four-stone earring cluster, a small accent row, or side stones in a ring design. The varying color tones within the set add a natural liveliness to any piece.
