Mother's wedding ring

As you can read by the Jeweler's appraisal, this ring is valued at $7,395.00 with 3 beautiful diamonds set in 14 karat yellow gold. I had this ring appraised one year after my mom's passing. Unknown size but it does have a hinged band to ease putting it over arthritic knuckles. The center stone represented my mom and the two side stones represented my sister and I. This ring was left to me by my mom and I wanted to leave it for my niece but she has fallen on hard times and I know in my heart that it would be OK to sell it and use the money to help my niece. I need to sell this ring quickly to get my niece out of living in her car and into shelter. And no, drugs or alcohol are not involved.
