Cutting a rough diamond?

My hubby bought me a platinum, solitaire set ring for our last anniversary. I love the ring's design but I'm not exactly in love with the rough diamond that was mounted onto the ring. I mean, I appreciate my husband wanting to get me unconventional, unique looking diamond jewelry, but I'm just not into rough diamonds and I really don't like the way they look. Can I have my ring's rough diamond cut down?

That depends on the rough diamond. Did you know that eighty percent of all mined rough diamonds are not gemstone quality? That means that only twenty percent of rough diamonds are cut and polished and used in jewelry pieces. True, your rough diamond was set into jewelry, but it may not even be gemstone quality. This new trend of using rough diamonds overlooks the fact that some of the rough diamonds may not be appropriate in jewelry to begin with. The first thing you would need to do is have your jeweler take a look at your rough diamonds. Ask him what he thinks about the diamond and whether, in his opinion, the diamond can be cut and polished. Most jewelers are not equipped to cut and polish diamonds and you may need to have your rough diamond sent to a licensed gemological laboratory so that they can determine how to cut and shape your rough diamond. For that you need to have your rough diamond removed from its setting. A local jeweler can do that for you. Keep in mind that if you do decide to cut and polish your rough diamond, that the gemstone may lose some of its carat weight. Rough diamonds that are cut and polished never retain their original carat weight since a lot of the rough matter is removed, in order to avoid the diamond being too included (a cleaner stone may result in a smaller carat weight). Also, not every rough diamond can be cut into any shape. The shape chosen for a rough diamond is contingent on the rough's natural shape and size. The lab you send your rough diamond to will recommend which shape you should choose for your rough diamond. Please note that the cutting and polishing process is not cheap. You may have to pay a large sum to have your rough diamond converted into a polished diamond. Not to mention that you would have to have the diamond re-set, which will also cost you extra, and that you may have to have the setting re-cast and re-shaped in order to accommodate your newly shaped diamond.
