Peace Celtic Pendant

I purchased the sterling silver peace pendant with Celtic knots around it .
It is very good quality and it looks exactly like the photos.
The only reason I have given 2 stars is partly my fault, I should have contacted the shop and asked for measurements.
I was rather surprised when I opened the box with a pendant about the size of my smallest fingernail.
I did email them and they responded and said they would put measurements up.
