Claim Text:
1. A method for determining locations of markings for the proportional placement of gemstones on portions of outer surfaces of ring shanks of varying finger sizes, where the markings identify center points for the placement of gemstones, where the shank includes one or more marking areas, where the gemstones are of one or more sizes, the method comprising the steps of: a) receiving ring information including a ring width, a ring thickness and a finger size that define an outer shank circumference, and a predetermined minimum space between markings; b) receiving gemstone information including a quantity of gemstone markings and a number of gemstone sizes; c) determining an available gemstone marking area based on the outer shank circumference; d) determining a number of spaces between markings based on the quantity of gemstone markings, the number of gemstone sizes, the outer shank circumference; e) determining that the number of gemstone sizes is one or two; f) determining, if the number of gemstone sizes is one, a gemstone size based on a difference between the available gemstone marking area and a product of the number of spaces between markings and the predetermined minimum space between markings, where the gemstone size allows at least 0.1 mm between girdles of adjacent gemstones, and, for ring shanks of 2 mm through 3 mm width, the gemstone size allows at least 0.4 mm from gemstone girdle to an edge of the ring shank; g) determining, if the number of gemstone sizes is two, a larger gemstone size and a smaller gemstone size based on one or more of the following: a quantity of smaller gemstones, a quantity of larger gemstones, the predetermined minimum space between markings, the available gemstone marking area, the number of spaces between markings, and a predetermined difference between the larger gemstone size and the smaller gemstone size, wherein: h) determining locations for markings within the one or more marking areas along the outer surface of the shank based on the quantity of gemstone markings, the determined gemstone sizes, the outer shank circumference; i) outputting the locations for markings; and j) creating a casting of the ring shank, the casting including the markings according to the locations.
