KARNATAKA  (MYSORE)  PROVINCE

 
     
        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.

iThis is the first rock I have ever seen from Karnataka  with the huge ruby crystals embedded in the matrix.  I found it in Tucson in February, 2008.  The second image shows a crystal about 4" (10 cm.) long.  The rock itself weighs about 118 pounds (54 Kg.)!            
 
     
 
 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.
 
     
 

TAMIL  NADU  PROVINCE

 
     
 
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 locallity.  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.

 
     
 

MISCELLANEOUS  LOCALITIES

 
     
  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.
