My mother has a diamond that is believed to have been purchased around the turn of the century. We are trying to find out it’s authenticity. We have found a card with the company name that manufactured the diamond. It also says that it is a corodite diamond. I have tried to find information about these, but have had no luck. Can you help?
Of a good appraiser could tell you in a heart beat what you got but in lieu of that, do the facets on top of the stone look a little worn?
