Gauhar is also used as a masculine name. However, it's more common for females. So, I think that the "Gender" of this name should be changed from "Feminine" to "Feminine & Masculine".
Gawahar, I understand, means precious jewel. The name of the first prime minister of India was Jawaharlal Neheru. Remember the moive Jewel of the Nile? The search was for the person by the name el-Jawhari played by Avner Eisenberg.
