Very rare transparent quartz crystals with irridescent orange rhombonedral faces with green accents. difficult to photograph, but most crystals show the effect when rotated in light source. We will include a copy of the 1950 scientific paper on this discovery by Sir CV Raman.
Of all the Rainbow Quartz we have received, this piece has the best "lights" of all. Many crystals at once show green, orange, or blue neon faces. Very rare specimen. The optical phenomena (Irridescent faces in Quartz) was first described by CV Raman in 1950. We can give you a copy of the article in the Indian Academy of Sciences.
Stalactite of AAA Rainbow Quartz, with entire faces of electric blue, green, and orange, depending on light source. Very strong and visible effect of Adularescence that is difficult to photograph, most Rainbow Quartz is like this. It is much better in person. This is a top quality specimen and will amaze you and everyone else with it's electric colors.
AAA Rainbow Quartz. Only from India, this quartz was first described in an article in the Indian Journal of Sciences CRYSTALS OF QUARTZ WITH IRIDESCENT FACES by sir C. V. raman who also discovered Raman Spectroscopy.(From the Raman Research Institute, Bangalore) Received May 10, 1950. Hard to photograph the intensity of the green blue and orange colored face reflec
Electric lights mimiced by this rare quartz that is dauphine twinned with polysynthetic twinning that causes color refraction or irridescence on most crystals. Resembles neon lights. Very rare to be in this quality. Way better in person because it's hard to photograph, but as you tilt the specimen different sets of crystals light up. Guaranteed to amaze.
Extremely rare and fine specimen of Irridescent Quartz. One portion is a cast of quartz deposited over once was a calcite crystal 2 inches in size. As specimen is rotated in light, the crystals show strong green lights across the entire crystal face, resembling electric neon lights. One of the best specimens of Rainbow Quartz in the world. $16 shipping charge in the US.
A very rare occurence of a zeolite on smoky quartz. The piece on the other side is a very aesthetic group of extremely black, brilliant smoky quartz crystals, with curved faces. There are also two unidentified minerals in micro size, green transparent acicular crystals, and the other laumontite, perhaps. The specimen is two in one, a beautiful smoky quartz group, and on the other side sharp orange
Very rare smoky quartz group with tapered shaped xls. Jack bought a small lot of these in a tiny one room shack in southern Bahia in 1978. There were small colorless beryls on some the quartzes. All were shaped in this tapered fashion.
Museum caliber specimen of Smoky Quartz from a pegmatite, showing "crocodile growth" on all sides. Has one feature of a tiny radioactive inclusion with a halo of smoky color around it. One of the finest Quartzes we have ever seen, this was sold to Dave Daniel in 2004. It is in perfect condition, very brilliant, and has infinite display possibilities. Click on picture to
Single crystal with reverse scepter shape, very complexly terminated. Flawless. One of the finest single Quartz crystals we have ever had, from Jack Lowell's personal collection. Light smoky/citrine color
