Abstract: Standard Diamond Parcels (SDPs) are certified for use in Exchange Traded Funds (ETFs). Three SDP colour types, Luxury, Premium and Privilege along with seven weight ranges simplify the complexity of diamond trading into twenty one different types of SDPs. Each SDP has ten diamonds, each diamond having a different colour/clarity combination. An SDP certification device, method and durable, non-transitory computer readable storage medium assures the characteristic of the diamonds in of each SDP type have a uniform valuation even though characteristics of the individual diamonds in each SDP may vary. One or more SDP may be grouped for use in an EFT unit.

Abstract: Further it is an object of the present invention to provide a method for evaluating a diamond comprising the steps of selecting a diamond to value, determining the shape, size, color, clarity and cut of the selected diamond, determining a base price of the selected diamond, calculating the applicable discounts/premium for the parameters of the selected diamond, calculating a weightage for each parameter of the selected diamond for which a discount/premium is calculated, calculating a total adjusted price based on the discount/premium determined, the weightage determined and the base price determined in step d, and outputting the calculated total adjusted price.
