Showing a select piece of Umbalite Garnet rough and in its rough-preformed state, 14.36cts currently
Natural, untreated from the Umba Valley, Tanzania
Like many of our gems, we work with this material from the rough, sorting and grading it for color, size, shape and clarity, before faceting it into different cuts and qualities. ▪
The next step would be final preforming followed by faceting and polishing, before final quality control and grading.
The process from mine to market is elaborate and it takes experience to produce fine quality finished gems.

Umbalite is a trade name for a pinkish-purple garnet from the Umba Valley, Tanzania.
It is a relative of Rhodolite and Malaya garnets – usually being a mix of Pyrope, Almandine, Spessartine and occasionally Grossular Garnets.
Almost all gem garnets are a mix of two or more species.
Pure Garnet would be colorless; it is the trace elements that give garnets their colors. For example, iron and chromium creates reds and greens; vanadium creates greens and manganese creates pinks and oranges.
Garnet is the birthstone for January, celebrates the 2nd anniversary and comes in almost all colors of the spectrum including the rare color-change.
Lots of choice for January birthdays!
