I have a diamond ring with the marks "KOBI 14K" inside. I know what the 14K stands for; but, what does the "KOBI" mean?

Thank you for using the Jiskha Homework Help Forum. Having worked for a jeweler, many diamonds come from Isreal and Kobi Roth is a reknown jeweler there. However many are 10K and not 14K. In Los Angeles, Kobi Katz is also famous for jewelry. If you take your ring to a reputable jeweler you should be able to find out where it was cut/made.
