I purchased a Cartier Trinity ring last year and found the service to be great and the price was certainly right! I was indecisive and took my time deciding and looking at various rings. At no time was I rushed or pushed to make a decision. The resale Items are all in great shape - fully refurbished and polished. While the ring I ended up choosing did not have papers or box, the markings are all correct. They guarantee authenticity or your money back.
