I've just purchased the above pendant with the letter "e" engraved on it. The circular shape of the pendant is to represent family. (It also helps that the circle is a rather sacred shape in mathematics and geometry.) The "e" engraved represents euler's number, which is the base of the natural logarithm. It's a number that naturally arises out of the study of compound interest. This is obviously relevant to a family heirloom that is to represent our wealth.
It's 14K gold and looks rather gorgeous.
I will wear it and pass it down to my future children as our family fortune grows!
