Looking For Buyers Of Blue Sapphires, Mandarin Spessartite, Green Tourm, and Specimens

Hi everyone. I am a young gem dealer from the U.S. I am looking for buyers of blue sapphires, mandarin spessartite, green tourmaline, silver topaz specimens, and black tourmaline specimens. As well as large citrine gems. I am relatively knew to the gem business, but I stumbled into an advantageous position where I can source quite a number of gemstones/rough stones (the ones previously mentioned plus Rubies, Diamonds, Garnet, Amethyst, Iolite/Ametrine, Emeralds, and Tanzanite to name a few) with the added disadvantage of not having a buyer market established. So I am in the process of establishing myself as a supplier so that I can get my business rolling. My degrees are in Biochemistry and Applied Mathematics, but I have always had a strong interests in minerals; gems to be specific. I am willing to answer any and all questions to the best of my knowledge.
