Sharp and GLASSY, transparent crystal with the best luster and very sharp striations culminating in a razor-sharp termination. An excellent specimen of the species.
Powellite (a solid solution series member with Scheelite) is hard to find itself, but almost never seen beyond opaque crystals. These crystals have everything you would want from any pow: excellent clarity; nice light to medium amber color; and superb luster. This piece has exceptional display qualities for these reasons and also because of the way the crystals are balanced on the right amount of matrix, for contrast. They are complete and pristine in front, though contacted in back. This specimen is way beyond almost any other Powellite you will find for the size and price.
An unusual association piece! Nestled among colorless, gemmy fluorapophyllite crystals are several tan, bi-pyramidal powellite crystals. Both species are very lustrous. The largest fl-apophyllite crystal is 2 cm and the largest powellite is 1.5 cm. Powellite, which forms a series with scheelite, is calcium molybdate, and reaches its zenith in India.
A superb doubly-terminatedcluster of , tan, lustrous and translucent, crystals sits on a druse of colorless, fluorapophyllite. The powellite cluster measures 2.5 cm in length. Once again, nowhere in the world does powellite occur, as well crystallized or as large as it does in India.
Thumbnail collectors arise! This competition quality specimen has lustrous, pink blades of stilbite, to 2 cm long, topped by a cluster of tan, translucent and lustrous powellite crystals, to 2 cm in length. Superb example of the species in tn size, and on matrix no less!
Powellite is among the rarest of collector gems. There is truly only locality in the world where facet grade Powellite occurs in any significance, which is Nasik, India. Powellites over 2 carats are rare, and the fact that this stone is over 5 carats is notable for sure. The stone is very well cut with an Emerald Brilliant cut and looks amazing face up. This gem is very very slightly included with a slight golden hue. I must say that this is one of the best gems in this update and would absolutely fit perfectly with a gemmy Powellite crystal as a "rough and cut" set. When it comes to the combination of rarity and quality, this stone is undoubtedly in the upper ranks.
Large, finely-formed crystals of powellite such as this are quite rare, and are highly sought-after by collectors. In fact, you can go through the inventories of a bunch of Indian dealers at a show without their being able to produce a single really good powellite specimen amidst many clunkers. Here is a sensational specimen, for size, luster AND translucency! The display is phenomenal, you could not design it better. The larger crystal sits on a natural "base" of a smaller crystal, with a spray of scolecite on it. You could hardly ask for a prettier specimen of this rare (in good crystals) mineral It would be a $3-5k specimen but for one small flaw – a shallow chip at one of the terminations. Still, look at the aesthetics of this piece! We felt this was probably one of the best powellites you could ever get for $1000 or less that looks so sexy and will stand over time against the crowd of lesser specimens in this price range.

This is a very rare large specimen of a new varietal of powellite that was identified during analysis of the szenicsite associations from this remote mine, only found in the 1990s by Terry Szenics. I bought much at the time, and saw no plates of this size for sale. It has some peripheral contacts, but the main display area is pristine and the display face is very large and colorful overall. To my knowledge, no more of this material has been found since the 1990s.

Another specimen, with limey-green color, the best you could ask for. As with the above, there is contact on the periphery which is visible, but you can see the almost gemmy crystals in the middle are in good shape. BETTER IN PERSON, with a 3-dimensional depth to this vug!

An unusual specimen in which the Szenicsite grew atop contrasting limey-green powellite, creating a green-on-green contrast that is very pretty! This is a pretty good Szenicsite on its own merits, with lustrous, metallic crystals to 2.2 cm. Usually the material is jumbled up and you see only the edges of lamellar growths , as the part touching the powellite here. However, the freestanding crystals atop are an inch long, and lay flat but well exposed on the underlaying thicker growth. 6.6 x 5.5 x 4.7 cm
2.8 x 2.8 x 1.5 cm. Two lovely blades of deep green Szenicsite, with the superb adamantine luster that is so classic for this species. This copper molybdate is very rare, with one and only one find ever. Adding to the quality is the gemmy green-tinted gemmy (cuprian) powellite along one side of the specimen.
14.2 x 9 x 6 cm. Vug coated with very attractive botryoidal to drusy cuprian Powellite, from the same famous locality as the discovery of Szenicsite. The grass-green Powellite is both gemmy and lustrous, and makes for rather an aesthetic specimen. The cuprian Powellite is completely different than the Powellites from India, so are an important addition to the collection. UNIQUE material all obtained from the discoverer, Terry Szenics.
6.4 x 4.2 x 4.2 cm. Powellilte is the rarest and most desirable mineral from the famed basalts of the Deccan Traps of India. This EXCELLENT and VERY SHOWY specimen features a 2.8 cm tall, sharp pyramid of highly lustrous and striated, gemmy, amber powellite aesthetically set in bladed stilbite. This fine piece is from the Indian discovery locality of the late 1970s - Pandulena Hill, Nasik and dates from that time period. There were not very many good specimens from the early finds. This is a beautiful, highly representative specimen of the species and locality and is not diminished by the partial contacting on the left side and back of the powellite, as you can see. Ex. Bob Jones and George Feist (#2527) Collections.
