A SUPERB CABINET specimen of HIGHLY lustrous rust-red hematite-coated amethyst crystals to 2.5 cm from the famous Thunder Bay, Ontario locality. This piece is MUCH BETTER In PERSON, as the deep red color was very difficulte to capture. A couple of trivial, trivial bruises to a few quartz crystals are barely noticeable. Old material, and knobs of this size are uncommon. Thunder Bay amethyst is a real pain to collect. I can vouch for that personally. A specimen like this is inficintely rarer and more desirable to me than the more common Brazilian amethyst. Plus, the red-on-purple coating is very appealing and unique 13.5 x 11.8 x 9.8 cm
