F++/Gem This is another treasure from Ecuador. It took me about 4 hours to clean this specimen from lime and preserve all the fine ridges and structures. This species is not rare, but few have the patience to clean it so thoroughly and carefully. The result exceeded all my expectations - it is a real work of art. You will be very pleased with this specimen. Don't miss this chance! Payment is possible in RMB via WeChat. I can also bring this specimen personally to Guangzhou in May.
