GEMERA offers investment in Colombian emeralds in exchange for GEMA tokens. The physical Colombian emeralds are stored in security vaults of safe deposit box companies. The precious stones will be selected by a group of gemologists and experts and certified by a specialized gem laboratory. GEMERA project uses the carat weight to establish the price of the emeralds, according to the Tone Range, along with the Clarity and Enhancement Classification. The marketplace will offer information on the assets such as pictures, video, characteristics, certification and GEMERA value. The emerald information and status will be stored on the Ethereum and the audit and recertification files will be on the IPFS. Token holders can redeem their tokens for the emeralds and then the tokens are destroyed. The redemption process takes place once a year and the date is announced to the token holders in advance. 3% redemption process fee is charged by GEMERA.
