I put this necklace on wish list for Christmas this year.  The piece just spoke to me.  It is my first piece of jewelry from the Amazon collection.  I was amazed at the quality when I opened the box. It is so much better than I had hoped. The pendant has a nice weight to it, but still feminine.  The polish and texture are consistent on both sides of the pendent.  The chain is thicker than what comes with most pendants too.  I'd say it's about 1mm.  The clasp is the spring kind.  I prefer lobster claw clasps for better security and ease of use, but that's a personal preference.  The bail is large enough that you can easily swap the chain with your favorite flavor and length.  I'm so happy with this necklace.  I'll surely buy more Amazon collection pieces.
