Real or Fake – The “Sardonyx” AKA Banded Silk Agates of Madagascar

############################# Video Source: www.youtube.com/watch?v=kDUF4ulTUFQ

I got some really nice looking sardonyx specimens from Madagascar a while back, and thought they'd be really cool if cut into cabochons. In this video I dive into the history of sardonyx, recent trade names, and the validity of the material. As it turns out, there are a TON of fakes on the market and now it's time to expose them for what they are! • My Etsy store: https://www.etsy.com/shop/GeocomMiner... • References: • Sard/Carnelian intaglio (public domain): • https://commons.wikimedia.org/wiki/Fi... • Onyx (Attribution: Rob Lavinsky, iRocks.com – CC-BY-SA-3.0): https://commons.wikimedia.org/wiki/Fi... • Sard and Sardonyx definition: https://www.britannica.com/science/sa... • Banded onyx with some flat layers (This file is licensed under the Creative Commons Attribution-Share Alike 4.0 International license.): https://commons.wikimedia.org/wiki/Fi... • Augustus Cameo (public domain): https://commons.wikimedia.org/wiki/Fi... • Sardonyx info (gemdat): https://www.gemdat.org/gem-7604.html • Onyx info (mindat): https://www.mindat.org/min-2999.html • Sardonyx info (mindat): https://www.mindat.org/min-7604.html • Music (free to use via YouTube Audio Library): • Arpeggisynth – Geographer • Island Dream – Chris Haugen • Six Seasons – Unicorn Heads • Sky Skating – Geographer
