Unfortunately most Americans do not understand nor use the Metric System. Most are opposed to implementing it in our school systems. But, anyone planning to have a career in the jewelry business had better have a working knowledge of the Metric System. I can just see someone trying to describe the length, width and depth of a diamond using the Imperial System. Although I once had a customer ask me to tell him how much his diamond was worth..........................over the phone. After explaining that I would have to see it to measure, weigh and grade the stone, he informed me "that it was about the size of a dime".
Yesterday I had a customer who wanted to purchase two .75 carat round diamonds for earrings. He also stated that he did not want to spend more than $1,500.00. I wish I could buy two .75 carat round diamonds at wholesale for $1,500.00.
