Rule # THREE
Gems are Gems, not Stones.
Potency counts.
Not the cosmetic value.
More on Precious Gems
Precious gems are very different from semi-precious gems and crystals. They possess some very specific characteristics and clients usually get them certified by laboratories. Blue Sapphire (Neelam) (External Link: https://thescientificastrologer.com/2014/09/15/most-powerful-gemstone-in-vedic-astrology-blue-sapphire-or-neelam-saturn/), for instance, is a very popular precious gem and it is supposed to be accepted only after thorough checkup both for quality and suitability. Below are some Tables (Source with courtesy: http://www.osfa.org.uk) to help subscribers understand the generic/natural compatibility. These are not thumb-rules but they come handy sometimes during analyses to keep it on track:
