@dominicanabroad: Herkimer Diamonds are rare double-terminated quartz crystals with a clarity and brilliance reminiscent of diamond gemstones. They are estimated to be ~500 million years old. So when you break open a rock and discover one, you’re the first person to see and touch it in 500 million years. Here are some Herkimer diamond mines you can visit in upstate ny: 1. Herkimer Diamond Mines (Herkimer, NY) 2. Ace Diamond Mines (Middleville, NY) 3. Diamond Mining (Little Falls, NY) 4. Mohawk Valley Mineral Mining (Sprakers, NY) Fun fact: They’re not as hard as true diamonds but up there. Diamonds score a 10 on the Mohs scale, while Herkimer diamond quartz rates a 7! I learned this the hard way when I accidentally smashed one into pieces trying to get it out of a rock :D TYSM to @thecrystalconduit who we met at the mines and gifted us with such a beautiful herkimer diamond!
