Abstract:
1. A computer-implemented method for determining precious metal content of an item of jewelry, the item of jewelry having one or more gemstones embedded therein, the method comprising: retrieving an image of the item of jewelry from a stored memory device; executing a programmatic edge detection process on the image determine edges of the gemstones; based on the determined edges, automatically selecting a shape of each of the gemstones; based on the shape and determined edges, calculating a plurality of dimensions for each of the gemstones; calculating a volume for each of the gemstones based on the shape and dimensions; calculating a weight of each of the embedded gemstones by multiplying the calculated volume by a specific gravity value associated with each of the embedded gemstones; and calculating the precious metal content of the item of jewelry by subtracting the weight for each of the embedded gemstones from a total weight of the item of jewelry.
