Andradite var Demantoid
stock #18.1-695
Tubussis Farm 22, Daures
Erongo Region, Namibia
6.2 x 5.4 x 4.2 CM (cabinet)
price: $875
Dec 2018

A fine cluster of stacked Demantoid Garnets that contrasts well with the matrix. Excellent color and luster, the main Garnets are 2.6 CM tall and in fine condition. No damage seen even under high magnification. The matrix is a mix of Quartz, Calcite and Prehnite, this holds several smaller Andradites as well. These were big mineral news a few years ago when they were more available, these are now quite scarce.
Andradite var. Demantoid- classic locality
stock #18.1-168
Sferiun Asbestos Mine, Vallone del Cengiaccio, Vaitellina, Sondrio Provi
Lombardy, Italy
6.8 x 5.9 x 2.9 CM (cabinet)
price: $475
Spring update

Choice Val Malenco Garnet specimen with several waxy green rounded Demantoid crystals perched on typical Amphibole matrix. The elongation of the 2.1 CM main crystal is impressive, and shows complex rounded faces. Classic specimen, these have always been prized and this is an older piece, sawn on the back as is common to enable collecting intact. The matrix has some cracks that may be old repairs or typical weakness in the fibrous structure of the matrix. Well above average quality best appreciated in person
Andradite var. Demantoid, Gem crystals with color change
stock #17.1-006
Antetezambato, Maherivaratra, Ambanja District
Antsiranana Province, Madagascar
6.5 x 4.9 x 3.1 CM (cabinet)
price: $900
Spring 2017

Top color and luster, bright sparkling gem Garnets are perched on a contrasting matrix of micro Garnets from white to pale green. In perfect condition damage wise, this is far better in person as the crystals are more brilliant than can be photographed. The color change from daylight to incandescent is also quite striking, daylight (or good led lighting) brings out an intense apple green as seen, the last photo shows the color by incandescent lighting. We searched out and examined a lot of the best Demantoids from Madagascar and only a few we consider great values. This is one that stands out.
Andradite v. Demantoid with Quartz and Diopside
stock #13.1-372
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Arusha Region, Tanzania
5.1 x 3.1 x 2.8 CM (small cabinet/ large miniature)
price: $485
Winter 2016-17

A really cute, bright specimen covered in sharp, gem grade Demantoid Garnets offset by a Quartz crystal. Finds of these Garnets have been sporadic and very few have had this sculptural form, grown on a Diopside base. The garnets fully cover the matrix on all sides, the smallest are a yellow color and the largest as seen are the Demantoid green. In great condition, damage-free and very lustrous, this is much better in person.
Demantoid (var Andradite) gemmy green garnet
stock #11.1-04W
Tubussis 22 Farm
Erongo Region, Namibia
4.4 x 3 CM (miniature)
price: $650


A cluster of intergrown, rich deep green gem crystals perched on a crystalline matrix. From the major find made in 2006, these were quickly absorbed into the market and disappeared. A very esthetic example of this uncommon variant, the largest crystal is 1.5 cm and is perched on other crystals. Far better in person! These show complex, lustrous faces and are undamaged.
