I have been purchasing the Swarovski ornaments via Amazon for a few years now, and have never had any issues, but that unfortunately changed this year. My purchase was direct from Amazon, not a Marketplace seller. The ornament arrived in pristine condition, but contrary to the description and the answered questions, the Certificate of Authenticity was NOT included. I have never had that problem before when buying these from Amazon, so I was quite disappointed by that fact. Buyer beware.EDIT (12/3/2013): As of today, the item description states that there is no Certificate of Authenticity included. That was not stated when I ordered this, or wrote this review. Some people also seem to have received theirs with a Certificate of Authenticity, as indicated in other reviews and the "Answered Questions" here on Amazon.EDIT (12/20/2013): In one of the comments of this review, a very helpful person (Lexi O) stated that she has emailed Swarovski and they confirmed that they are no longer including the certificate of authenticity as of this year. What does this mean? Many people have stated that theirs did arrive with a certificate of authenticity. If I had received one of those, I would now be questioning whether or not IT is authentic. As that is now the official word from Swarovski, I am adjusting my previously three-star review up to being a five-star review. This ornament is absolutely gorgeous, and is a true treasure on the tree or an ornament stand.
