This Old Mine diamonds was cut and polished in Europe, probably London or possibly Amsterdam, before the 1870s when technology and power required to shape a diamond’s outline to a perfect circle were introduced to the diamond cutting factories. The geographical origin of the diamond is probably South Africa, possibly Brazil or India. There is no scientific method to determine the geographical origin of natural diamonds.
The 18ct UK hallmarked ring is of modern manufacture.
