Around 1999, huge ruby crystals were beginning to appear at the Tucson Gem and Mineral shows.  Their origin was somewhere in Karnataka, but because the Indian government tends to take over profitable mines, the miners will not reveal the precise locality.  When asked where it came from, he will likely answer:  "From the ground!"   The names "Red Mountain", "Ratnapuri", and "Subramaniam"  are names I have heard at one time or another.  

18 pounds

 Budhipata (Budhipada) is another locality that produces smaller ruby crystals in gneiss.  Both matrix specimens and loose doubly terminated crystals are highly collectible.  Note also the translucent modified prisms and twins on the left - these are unusual.
 Two huge specimens from the Subramaniam mines in Karnataka Province, India were picked up (with some difficulty)  in Tucson in 2009 and 2010.  The 118 pounder on the left has embedded rubies up to 4" (10 cm.) across.  Note the halo of blue zoisite in the third image.  The amphibolite specimen on the right weighs about 165 pounds (note large garnet in upper left). 
Since then, additional large matrix specimens from Karnataka have appeared, and for reasons that escape me I have been hoarding them.   Two specimens of ruby in amphibolite appear on the left.  On the right is a 194-pound massive ruby with a vein of green zoisite or fuchsite running through it.  Note the gemmy  recrystallized ruby on its surface (detail, far right). 
The specimen on the left, also from Karnataka, weighs over 90 pounds.  It is probably massive corundum in the center, with recrystallization on the surface causing the mottled appearance.  On the right are specimens of what may be hydrothermal ruby in pale blue cordierite, from the Orissa Mines



On the left is a purplish star ruby cabochon from Tamil Nadu Province, India.

Next to it  are some interesting terminations of 8 pound crystal from the same locality.  This remarkable specimen may have survived because it was too big for the cabbers' saws!  (Also, this one does not indicate asterism.)

On the right are some small gem rubies from the province.


   These are the first corundum specimens from a new discovery in Tamil Nadu Province, India.  Two views of the best cluster of tabular crystals are on the left, and images of the two strangest are shown on the right.  In the last, note the aftergrowth of ruby on grey sapphire.



  The pale tabular prism and the greenish crystal are of unknown Indian origin.  The ruby "spear point" is  from southern Madras.  The crystal on the right (two images) is from Hyderabad.
