Good Morning Sherri
Hope you are doing well,
Please keep in mind if another expert answers behind me and you are happy with my answer, please make sure to click the rating for me! It may appear confusing since their answer would come in to your email after mine does.
Is this a CZ in the ring? Marquis cut and is that small channel set Cz's to the side?
I could not find that maker either. Normally if a ring like this is a real diamond they are in 14kt Gold.
But that is not always the case either. The Karats will make a big difference in the value. You really need to take this to a jewelry store, they will be able to look at this and tell you if this diamond is real or a CZ they can tell you by looking at it with a loop. THere is really no way to know by seeing it online or what karat it is.
If you get it looked at you can come back tell me what they said, I can then look it up for you.
I did not do this as an answer because I did not give you a value for your ring, and I did not think it was right to do that since I did not give you what you were wanting.
When you find out what it is, just come back to this question and I can give you some ideas where to sell it.
