Natural Tanzanite 0.27ct 3.7mm Round Cut

A natural tanzanite round cut with a cool, muted steel blue-violet color and a sophisticated, understated tone. The stone shows a quiet depth of color with an attractive star-burst light pattern through the round facets, and the slightly gray-blue body gives it a calm, refined presence different from brighter lavender examples. Natural needle inclusions are visible at SI clarity.

From the Merelani Hills of Tanzania, this heat-treated 3.7mm round suits jewelry designs where a cooler, more muted tanzanite tone is desired. The steel blue-violet works particularly well in minimalist settings and alongside diamonds or white metals.
