If you receive negative feedback for poor communication is angeling the only way to change it? You obviously can't make it up by sending the package to your partner since it's only communication you received the negative for.
I saw a ring similar to this on Etsy. It sold. I found a seller that sold rough cut diamonds. It took me forever to find wire small enough. I had to use 30 gauge. I thought I was going to go blind getting the diamonds on the wire.
