Victorian sapphire and diamond brooch

This brooch was meant to be part of my personal collection, but I am whittling down to make room for something else. That means you have a chance at it. What drew me to this particular brooch is obviously the use of color, and also the patina on the gold. It’s 15 K but has that wonderful rosy color that only happens with age, and the gray patina in the middle does something to really make the stones pop. This would be fantastic on a pendant or just worn as is. What also drew me to it are the natural sapphires. I’ve worked with sapphires like this before and they look unheated to me. I didn’t get them certified, but they appear to be Cambodian. The diamonds are all old European cut or old mine cut and are very white, all matching and I would say EF color. The clarity is lovely as well, I’m not seeing any giant issues with any of the stones, but I’ll safely safe they are SI1. It has approximately 2.5 CTW of diamonds, it is just over 2 inches long and just over 1 inch at its widest point. It weighs 13.04 g
