International Classification:

G06F017/60

US Classification:

705042000, 705043000, 705044000

Abstract:

An exchange trade fund comprising: an amount of currency, wherein the currency is deposited with one or more custodians in exchange for one or more creation units; wherein each creation unit represents a plurality of shares of the fund; and wherein each creation unit is redeemable for an amount of the currency equal to the net asset value of the creation unit plus interest and less fund expenses. Also disclosed is a closed end fund comprising: one or more currencies deposited in short-term bank instruments; and the distribution of shares of the fund to one or more investors, wherein the shares of the fund have a net asset value based on a combination of prices of the one or more currencies from a plurality of sources, and wherein interest earned on the short-term interest bearing instruments are paid out to the one or more investors as a dividend.

US Classification:

705500, 356 30, 209592

Abstract:

A process to create a fungible global standard for diamonds and gemstones. The process involves grouping diamonds in an investment standard according to their gemological, proportional, optical and light behavior characteristics. Diamonds that conform to the investment grade standard are interchangeable within a specific size range according to an equivalent monetary bundling process. Diamonds subjected to the standard conform to a holistic set of gemological, proportional, optical and light characteristic requirements that enables diamonds to be classified into a extraordinarily homogeneous, visually indistinguishable and highly fungible group which can be used to create baskets of diamonds to form an index/benchmark for diamond pricing, financial instruments, and a standard that can be used for certifying diamonds as investment grade to insure quality.
