A wonderful pair earrings
Of purple garnets of Mozambique, this is a rarest garnet ever found
With beautiful combination of tsavorite garnet
The most exciting gem at this year's Tucson gem show was a rare Purple Garnet from East Africa. There were found in Mozambique, with the finest material coming from the Mozambique mine. Indeed, the top grade pieces were among the most beautiful garnets we've seen anywhere. We were lucky to be one of the few dealers able to acquire some of the finest of these unusual gems.
What's special about these garnets is the wonderful color -- an intense purple with red flashes that we call Royal Purple. The Mozambique material in particular has a bright open color with wonderful brilliance. If this wasn't enough, these garnets also display a fascinating color change, from grape under daylight to cranberry with magenta flashes under incandescent lighting.
The GIA lab in Bangkok did some analysis of the Mozambique purple garnets and published their findings in the Fall 2016 edition of Gems & Gemology. The material they tested came from a mine in central Mozambique in Manica province close to the Zimbabwe border.

Purple Garnet is a rare hybrid garnet found its is The finest material, from Mozambique, has an amazing vivid purple hue with red flashes. These rare gems display a color change from grape to cranberry with magenta flashes.
A rare combination of pyrope-almandine garnet with the following chemical components: 48.8-59.5% pyrope, 37.9-47.6% almandine, 2.0-3.5% grossular, and 0.5-0.6% spessartine. Though the chemical composition classifies these gems as rhodolite garnet, analysis of the absorption spectra showed some unique properties. Since the main absorption bands dominate the green-yellow regions of the visible spectrum, two strong blue and red transmission regions combine to produce an eye-visible purple color, and also account for the strong color change.
Under cool light these gems display a rich grape hue. But under incandescent light, which has more wavelengths in the red part of the spectrum, these gems display a blazing cranberry color with magenta flashes. Under balanced lighting, they are an intense purple with red flashes.
The material with the best color is found in smaller sizes, under 3-4 carats. Since the color saturation is so intense, larger stones tend to be too dark. Though the highest grade material has come from the Mozambique deposit, both the Tanzanian and Mozambican material display the distinctive color change.
