Abstract: A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. The cryptographic token is written to a blockchain using a smart contract that is configured to enable a transaction associated with the token in response to two or more of: a signature by the encryption chip, a signature by the owner of the diamond asset, and a validation of a visual layout of the diamond asset.

Abstract: A tamperproof diamond package comprises a package body; at least one chip embedded in the package body and at least one antenna configured to enable communication with the chip; anti-counterfeiting visual impressions on the package body; a diamond pouch formed at a predetermined section within the package body; and one or more diamonds located inside the diamond pouch and an outer covering encasing the package body and configured to reveal any tampering with the one or more diamonds located in the diamond pouch. The diamond package can be credit card shaped and also contains serial number and website information and be provided in nominal dollar values. An associated diamond exchange system utilizes the diamond packages and provides a registration server which stores unique identifying information that enable interrogating the individual diamond packages and checking their authenticity with the registration server.

Abstract: A market maker system associated with a diamond-backed cryptographic exchange stores for each of a plurality of diamonds, a rating of the diamond according to each of multiple properties. The system receives ratings of a target diamond for each of the multiple properties. From the stored diamond ratings, the system selects one or more diamonds with ratings within a threshold distance from a specified rating of the target diamond. A dynamic order listing the selected diamonds is generated.

Abstract: The application describes generation of a data structure that enables comparison of any diamond to any other diamond. The data structure is generated via a sampling process and a computer system for acquisition of diamonds of a valid statistical sample having a predefined sample size. The process comprises tabulating the frequencies that diamonds of various grade combinations are available in an overall population of diamonds, then using a bidding process described herein to acquire a valid statistical sample of diamonds. The data for the sample of diamonds are then inputted into a Linear Programming and Mixed-Integer optimizer configured to sort all diamonds of the sample into sets with a median that is a minimal distance from the median on a scarcity basis, subject to various constraints, such as the number of diamonds in each set and a minimum total carat weight.

Abstract: A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. A user device executes an application programming interface configured to access a blockchain that stores a smart contract associated with the cryptographic token backed by the value of the one or more diamonds. When the user device receives an instruction to perform a transaction related to the cryptographic token, the user device causes the encryption chip to sign the smart contract. In response to determining that the smart contract was signed by the encryption chip, the user device causes the transaction to be performed.

Abstract: Described in this application is a secured smart cabinet having a plurality of retractable shelves mounted therein for storing a plurality of assets with wireless encryption chips for authentication sealed with each asset. Each shelf is partitioned into a plurality of compartments configured to hold an asset and to enable wireless communication between a wireless senor and a wireless encryption chip. A processing system is configured to command the wireless sensors to audit, authenticate and interact with the wireless encryption chip in the asset and exchange data between the processing system and an authentication server. The exchange of data could include receiving commands from and sending authentication results to the authentication server. The smart cabinet also includes a network device to enable the exchange of data between the processing system and the authentication server.
