Module B Learning Outcomes summary study guide complete and verified 100% Summarize the historical sources of diamond prior to 1867 - -Historically, diamonds were extremely rare and sourced from only a few scattered alluvial (i.e., within river gravels) localities. They were *first discovered in the Golconda Region of India* and then *subsequently in Brazil* by the 18th century. It has been supposed that a maximum 50,000 carats could have been produced annually from India before the 18th...
