@thejourneyofagem: Day 65/75 becoming an Accredited Gemologist ~ natural v.s. synthetic opals. There are synthetic (lab grown) opals produced by the sedimentation process which have the same properties as opal except they display a snake skin pattern and have a columnar structure. Other ones to watch out for are: - Slocum stones which are plastic wrapped in a foil to mimic the play of colour phenomenon. - doublet/triplets which can easily be identified if not set into jewellery. We learned about ‘snake skin pattern’ in our Gem ID class so when I came across that perfect honeycomb pattern in the Ethiopian opal I was surprised. Benefit of studying in the jewellery trade centre where I’m being exposed to every single variety of gemstone. What else do you want to know about Opals as it’s still October (birthstone month) 🤍 #gemlover #gemstones #gemidentification #semipreciousstones #gemfacts #gemexplorer #opaljewelry #opal #opalstone #opalrings #ethiopianopal #syntheticgemstones #syntheticopal
