Beautiful gold, bigger than anticipated
Color: Warm Gold, Color: Warm Gold
This is very pretty and matched my gold fixtures well. It is a heavy piece. I was a little surprised because I anticipated it being smaller, however it’s rather substantial. I don’t mind the look and did keep item. Everyone in the family noticed, and I live in a house of boys so that’s saying a lot.
