You're seeing the last of the Leiping calcites - this large plate is actually from a batch that was in the back room of a Chinese dealer, and we bought the only good ones left. These calcites are distinguished by the prodigious size of the fat crystals (up to 5 cm across the sharp pyramidal terminations), and internal hematite-coated phantoms inside of the crystals, formed during the first generation of growth. These are wonderful under UV light! 15.9 x 9.4 x 5.9cm
