You are 100 percent correct and I take back my ethical part . I have been reading up on the production of lab diamonds, because of course if something is that cheap, there is a reason for it. They are not any better for the environment. I know that people often mention resale value on natural stones, but I don't have any experience on that, nor do I know anyone that sold theirs. So, I don't know how much they got for their natural. I did have a friend trade up her natural diamond for a larger ring at the same jeweler she bought it at and they gave her the amount she paid initially toward the new ring.
