5mm Faceted Trillion Tanzanite

Tanzanite is found in only one location in the entire world — the Merelani Hills of Tanzania in Eastern Africa. Discovered in 1962, tanzanite is a relative newcomer on the gemstone market, yet it has grown incredibly popular among jewelers and collectors alike. This 5mm faceted trillion-cut tanzanite showcases the gem's signature pleochroic character, displaying shifting color depending on the viewing angle.

Pure blue to violetish-blue hues are prized in tanzanite, and these stones fall within that desirable color range. Eye clean in clarity, they are well suited for setting in fine jewelry. Tanzanite is the birthstone of December, making it a meaningful choice for custom designs and finished pieces intended for resale.

Because tanzanite is sensitive to thermal shock, it must be handled with care during setting and finishing. Always clean with warm, soapy water — never expose to ultrasonic or steam cleaning equipment.
