I think need to have minimum posting then can post links to show the images. Usually they ask lynn to help them post the images. i'm sure she or the others who have met the minimum requirements to post images will help you too if you ask them nicely.
different places might have cheaper diamonds with the same paper specs. but that does not mean it is a good diamond as that is only the first filter to check whether if it is a good diamond or not. that's why we refer to other filters such as HCA or scopes to tell how gd the diamond is. JP has a good reputation and quality of diamonds is rather consistent.
True , its seems that they have filter out the "better" diamonds but nonetheless i believe that Jannpaul has advertising features with HWZ or rather, most probably they have employees within this thread to facilities their branding and up selling their products.
Basically it just means that doing a direct comparison to Cartier/SK, JP emphasis more towards the quality of the diamond. at the same time , i believe if one has the necessary knowledge to weed out diamond and has a good sense of diamond price, its possible to find a quality diamond lower in price.
nonetheless, personal opinion still stand @ JP setting are rather expensive, they are selling more towards a experience rather then the product itself and the consistency of the better diamonds are somewhat or rather assured although as usual; its comes at a premium which is nothing unique.
Like most jewellers, Diamonds in JP might not be a 1st hand product if some of the buyers are particular about. its just a cold hard truth across the board.
