The ring size is 2cm in diameter, the flower that is the head is 3cm, and the ring itself appears to be made of 18k gold. The petals of the flower are a pearly white color and bordered in 18k gold. The Chanel trademark logo with interlocked C's is on the top of the right largest petal in the same gold color
I purchased this item a long time ago from a garage sale when I was younger and was oblivious to the potential value it might have until now. (This means I'm not 100% sure if its real which is why I need help)
