I wanted to give a quick head's up that this particular ring does seem to come up quite generously on the sizes. I ordered M - my ring finger is an L, and my middle finger is generally about an M to N, and the size M in the Nugget ring (both sizes, but more on the Large one) feels more like an N1/2 to me. I think it is because the gem is raised from the ring in an open setting to allow stacking more easily, which results in a bit more 'give' in the ring - see the picture below. I ordered the Large Nugget online and took it into the Monica Vinader shop on South Molton Street to check I hadn't accidentally been sent a size P (I hadn't). I could easily wear the size K on my ring finger, so it is worth bearing this in mind when ordering this particular style online, or ideally trying them for size in a shop first.
