Cuprite and Copper specimens from the Rubtsovskiy deposit in Russia. Like the past couple of years, these Cuprite and Copper specimens were plentiful at Tucson with flats of partial crystals and crystals clusters with some damage or contacts available for $20-$200, with more value placed on perfect crystals, Cuprite on Copper, and the psuedomorphs of Copper after Cuprite. Although plentiful, all the Russian dealers said the deposit is is no longer producing (all the specimens are out of the ground) so it is unclear how much longer these will be available. 2024-04-18 04:40:02 (PDT): Warning: Cannot modify header information - headers already sent by (output started at /mnt/vol-01b7ce02a4fa81bb8/data/mm/www.marinmineral.com/navbar.php:403): /mnt/vol-01b7ce02a4fa81bb8/data/mm/www.marinmineral.com/s_present.php: line 39
