Last year I made a colored gemstones collection as an asset for Blender Cycles (procedural materials). People liked it and quickly mentioned that creating it for Octane would be very interesting.
Octane clearly has very high quality nodes. It was indeed very interesting to port Cycles materials to Octane. The nodes react quite differently.
The asset for OCTANE file formats are ORBX, ALEMBIC y BLEND for compatibility. https://blendermarket.com/products/octanerender-procedural-colored-gemstones-collection

The minerals I’ve recreated do have inclusions nad flaws like there natural counterpart.
The actual mineral list includes:
Diamond, Corundum (Ruby, sapphire and color sapphire), Beryl, Tourmaline (with real life double refraction setup), Quartz, Opal (works for light and dark and all colored shines), Malachite, Lapislazuli (with inclusions), Agate (works for all colors), Pearl, Turquoise (with or without pirite and dirt inclusions).
