Didn't they develop some type of photographic finger print for diamonds and their inclusions? I thought I saw that on the news(years ago) for some high end diamonds. That way they can keep a record of the owners. If they were stolen or lost then they could be traced back to the seller/owner. I assume a diamond of that size would be "high end" and have a record of it. Congrats! that's a bucket list item for sure.
