Wow! What a treasure! I've always been fascinated with crystals and gems. I went to the Harvard Natural History Museum and they had a fantastic collection. I've never been in an area where gems are located but I use to go hunting for fossils and found a few neat ones. There was a recent discovery of diamonds in an area a couple of hours drive from our place. When the news first came out about this find I was planting trees close to the area and I kept a close look out for diamonds but alas nothing. I didn't really know what I was looking for. That's great knowledge you shared for knowing what to look for. Thanks for sharing!
