Too warm is subjective, colour is entirely personal preference. You bid on it for a reason so I assume that you like it, and wanted to purchase it, right? It looks like a rose cut diamond?
If the seller has a return policy, you can always return it if you see it in person and don't like it. I don't know what to tell you if the seller doesn't have a return policy.
Well there is something you don’t see everyday…a marquise rose cut!
Color is very personal so nobody can really answer if you made a mistake or if the diamond is too warm. It’s all about what is pleasing to you. Although I like the setting a lot, a diamond of this color would probably even be further enhanced if the head it’s set in was yellow gold.
First things first, wait to see it in-person, then you will know for sure. Also try not to stress, it looks very clean and the setting is beautiful!
Is the stone certified? It looks warm for that grade, even with the rose cut.
My big concern would be did you pay a fair price for what it is. Without knowing the details, hard to say.
If you are questioning too warm, you may have your answer.
I actually love warm rose cuts. Usually I am attracted to them right away. I prefer them set in yellow gold or at least a yellow cup. I think if you bid on it then you do like it.
Completely one-of-a-kind. I love it. The tint really gives the stone major character, and you'd be hard pressed to find something similar again. It would be a keeper for me.
