Not exactly a gemstone, but a WHOPPER corundum (sapphire) crystal, of textbook hexagonal form, from Zimbabwe - apparently purchased in 1981 according to the Ed Ruggiero index card that came with it. Light blue-gray color. 4.8 x 4.3 x 4 cm
0.7 x 0.5 x 0.3 cm
This is one large corundum var. ruby, weighing just over one pound. It is a complete, doubly-terminated floater with good luster and superb, saturated color of pigeon’s blood red. The hexagonal form is well-developed but elegant for such a large beast, in that it tapers gently from teh center to the terminations. The crystal IS a complete floater, in tact all around even on the terminations. There have been literally thousands of these available over the years but few as large or as good as this one. 9.4 x 5.5 x 3.5 cm
A SHOWY and excellent CABINET plate of highly lustrous, striated ruby corundum crystals in lustrous, layered phlogopite from the well-known Kleggasen Ruby Quarry in Froland, Norway. Ex Dick Hauck Collection. RARE! 10.5 x 9.0 x 2.4 cm
Two intergrown, complete all-around, translucent, pigeons-blood red ruby crystals from an ancient and very historic locality that is now difficult to find specimens from The two backlit photos highlight the color intensity and translucency. 2.4 x 1.7 x 1.6 cm
SHARP doubly-terminated floater with a stunning, unusually deep royal blue color! 2.5 x 0.4 x 0.4 cm
a very pretty, deep red ruby of classic "pigeon-blood" color, perched nicely in contrasting matrix! The ruby shows exquisite form and has the best color. It is somewhat translucent but not gemmy per se (as these tend to be). The crystal measures 2 x 0.8 x 0.7 cm in size 5.4 x 4 x 3.8 cm
Two lustrous, gemmy and sharp, intergrown blue sapphire crystals from the Ratnapura, Sri Lanka. Classic material. 1.6 x 0.9 x 0.7 cm
A large, lustrous, weirdly shaped crystal of ruby on matrix, measuring 2.5 cm across. The crystal is complete and undamaged, and shows lots of shiny faces, despite its odd form. There is a second crystal nearby, and some accenting muscovite. 6.7 x 4.8 x 4.5cm
A large, sharp and complete ruby crystal, measuring just under 2 cm across, wonderfully trimmed without damage and well exposed on the marble matrix. 5.5 x 5.2 x 4 cm
While it is not exactly a gem crystal, this IS a ruby crystal, and not only that - it is HUGE, euhedral (fine hexagonal form), and doubly-terminated! If you want to amaze a non-collector, show them a ruby so big they can hardly hold it in their hand! This monster weighs 3.3 POUNDS! 15.1 x 8.6 x 7.1cm
To go with the gigantic ruby crystal elsewhere in this auction, here is a fine LITTLE one! Unlike the large one, this one actually is translucent in good light. It has fine hexagonal form, and is terminated on one end. 1.6 x 0.6 x 0.6cm
A sharp, lustrous and euhedral, floater, rust-brown corundum crystal from a famous South African locality, Soutpansburg. This fine, old-time Richard Hauck Collection piece is undamaged and has an old label. 3.8 x 2.6 x 2.5 cm
For both size and quality, this is one of the very best examples of the recently found bicolored Corundums from Madagascar. I exchanged it directly from Dr. Federico Pezzotta who collected it while doing research there. It features a 1.0 cmlong crystal perched smartly on matrix. These corundums are generally called sapphires on the market but to me, I cannot decide which to label them as. They go varying shades of red/purple and even to blue-purple depending on which lighting source you use to look at them. The effect is not subtle, either - its pretty obvious. 6.0 x 3.8 x 2.7cm
The pigeon’s blood color in corundum is called ruby. All other colors are sapphire. THIS piece has THE color! The deeply colored ruby, 1.5 cm across, is translucent and highly lustrous. The crystal, 360-degrees complete all around, is aesthetically perched on contrasting white marble. 2.1 x 1.4 x 1.3 cm
