I bought this necklace for my 12 year old daughter, because she love dolphins. She loves her new necklace and wears it all the time. This piece is beautiful and I love how the big dolphin and little dolphin make a heart.  The necklace is true in length which is 18 inches, and the chain is decent.  It is very well made and durable. The pendant is a good size that people will notice it. The necklace is stamp .925 on the back. The only thing I don't like about the necklace is the clasp needed to be bigger.
