Theoretically, the garnet group is comprised of two mineral series - the aluminum silicates, consisting of pyrope, almandite and spessartite; and the calcium silicates, consisting of uvarovite, grossularite and andradite. The main differences among these members are slight variations in color, density and refractive index. Despite being distinct species with very distinct compositions, all garnet varieties share the same crystal structure; rhombic dodecahedron, twelve-sided crystals with rhombic faces. This crystal form is the hallmark of all garnet gemstones and minerals.

How many different types of garnet are there?

Where can I find color change garnet?

Color Change Garnet is an unusual variety of Pyralspite primarily found in African countries such as Madagascar, Kenya and Tanzania, but also in Sri Lanka and Afghanistan. This Garnet variety is found in every color except red and black. The color of Color Change Garnets is modified toward the red end of the spectrum when incandescent light is applied. This is because incandescent bulbs themselves cast a “warm” reddish hue that brings out the red color from minor amounts of chromium within the Color Change Garnets.

What gems have color change?

In addition to the Garnets that are classified as color change by gemologists, color change can also occur among Almandine, Spesssartine, Andradite, Grossular, Malaya and Pastel Pyrope gems. However, the variety name “Color Change Garnet” is generally reserved for Pyrope-Spessartine Garnets, which at times show the most definitive color change. With compositions that fall along the join between Pyrope and Spessartine in the Pyralspite ternary, we see a nearly continuous isomorphic replacement between Pyrope and Spessartine. This researcher has tested Color Change Garnets with compositions ranging from a low of 30% Spessartine to a high of 89% Spessartine.

How to tell if a gem has chromium?

Chromium can be detected in this gem as red fluorescence under blue laser light (405nm), and chromium is also clearly detected with a spectrometer. Fluorescence in Garnets is usually restricted to the two allochromatic species Pyrope and Grossular, and as far as we know, fluorescence in idiochromatic Spessartine has never been reported. A similar example of chromium-bearing Spessartine from Madagascar was reported in 2002 ( Schmetzer, et. al. 2002 ), but fluorescence in that gem was not described.

Why does pyralspite garnet have fluorescence?

Fluorescence in these Pyralspite garnets is due to chromium, and is permitted by a relatively low concentration of iron. In many cases, the presence of chromium can be confirmed by a red Chelsea filter reaction. In other cases, no Chelsea filter reaction can be seen (as in some brown and orange Color Change Spessartine Garnets). In these cases, only trace amounts of chromium are present, and such low chromium concentrations contribute nothing to daylight gem color and nothing to magnetic susceptibility. I suspect longwave UV fluorescence in many Color Change Garnets is quenched by vanadium rather than by iron.

What is the color of the pyrope?

The spectrometer graph below illustrates how chromium/vanadium in the presence of manganese creates the blue daylight color and red incandescent color in blue Color Change Pyrope from Madagascar. Absorbance of light in daylight is seen below as the peaks for manganese (Mn2+) and chromium/vanadium (Cr3+/V3+). Transmission of blue light occurs in the valley near 475nm, and transmission of red light occurs in the valley near 700nm. The area of transmission of blue light in the visible portion of the light spectrum is a bit greater than the area of transmission of red light, translating to predominantly blue color in daylight. But when reddish incandescent light is applied, the area of red light transmission shifts to the left and becomes dominant.

What are the refractive index ranges for color change pyropes?

The measured refractive index range for Color Change Pyropes is R.I 1.742-1.768, and the magnetic susceptibility range is SI 14.45- 24.53. Broader R.I. and SI ranges are seen for Color Change Spessartine gems, with RI 1.751-1.792 and SI 24.35- 41.79.

Is Spessartine Garnet chromium-bearing?

We classify this extreme example as a Color Change Garnet, but it could also be classified as a rare example of Spessartine Garnet that is chromium-bearing. The presence of chromium enables the color change.
