I have a couple of uncut stones. One I believe is a round uncut ruby a little over 1/2 an inch in diameter?

It's exterior is rough with gouges but when I hold it up to the light I can see that it has a deep red color on some of the edges. The other stone is a rough, mottled blue stone. I thought it might be quartz, though I haven't been able to find a pic of quartz with this vibrant of a blue color. It measures 3"X 2.75"X2". I don't think it's very clear/transparent and it's quite dense and heavy. Both stones are pretty heavy for their sizes and I've done little more than clean the dirt off of them, so I'm not sure. They were both found in North Carolina. Any clue as to how I can find out what they are (especially the blue one) and what they may be worth (if anything)?

    The red one is more likely to be a garnet. There are several blue semi-precious stones around so I can’t answer that one. I suggest that you take them to your local rock collecting club.

    Garnet is definitely the most likely option for the red one. Other options include glass, spinel, CZ etc.

    The blue one could be glass, sapphire, topaz or a multitude of other possibilities. I can’t recall any blue varieties of quartz off hand though.

    If the Gemological Institute of America (http://www.gia.edu/) has a branch near you they may be able to help or, of course, someone at your local rock collecting club.

    A quick google search indicated that emeralds, rubies, sapphires, garnets, moonstone, aventurine, amethyst and citrine are all gemstones found in North Carolina. So, if not glass, the most likely option for the red one is ruby or garnet and the most likely option for the blue one is sapphire.
