Movado Diamonds

No idea. However, this is not very hard to figure out just by asking the suplier the right questions. Such issues ("how do the diamonds of XXX retailer rate") are often mentioned here: I guess Movado's are next... Usually, the conclusion is "not great". First I have to say that "diamond rating" on Pricescope focuses on the cut quality (ON TOP of the other Cs) and the optical properties (sparkle, or light return) of rounds, but also other shapes. If how bright and sparkling your diamond is matters, than Pricescope's is the right approach for you. There are not too many instruments or methods to evaluate the light return of a diamond, so, if you know that the stone you are interested in has not passed such light return tests, you may want to pass the stone and consider an altrnative vendor. In absence of any objective evaluation of cut quality, it is hard to rely on your eyes only (or the vendors!) without having seen a truly wide selection of stones yourself. For example, the cut quality guarantee for the e-ring diamonds sold by

Debeeers and Tiffany do not cary such evaluation for optical properties.
Each seller can devize its own cut standards, it is a good thing to ask what the standard guarantees. The industry itself has such cut benchmarks already, such as the AGA's. ( HERE )

What this optical properties I am talking about are and how are they measured is explained in some detail in Pricescope's cut tutorial. Other such references are listed by the GoodOldGold site and Preciousmetals . Other sellers use such standards too: this is not an endoresement for these sellers only... If you are willing to pay what can be a steep premium for a name, it may be a good idea to investigate these issues. Diamonds with great cuts do not necesarily cary a brandname. These are usually bought loose, and if you decide to buy them online your cost is bound to be lower per carat (if this matters, or the stone can be better if you so choose).

Hope this helps
