It is unusual to find Tanzanite biolettes and these are first class quality tear drops on fancy Sterling silver earrings. The Tanzanites are the perfect purple-blue colour of Tanzanite, unlike lesser quality stones which are too purple or too blue. Dainty but affordable for this precious gemstone.
Tanzanite has been overmined and the availability and quality of the stone currently being mined is much diminished. Fortunately these stones are of high quality and excellent colour saturation.
