Reply To: What’s the point in “real” jewelry?

The RAMBAN by the choshen in shemos has a long piece that goes through the stones in the choshen and ascribes “powers” to them
For example, the ruby is reuvens stone and connects to the story of reuven bringing his mother mandrakes, which apparently have fertility powers (and that is why he was bringing them to Laya) so the ruby stone apparently has fertility powers.
Hence the extremely popular minhag for pregnant women to wear rubies.
Our religion also ascribes “powers” to zodiac signs. You can argue as to whether it still applies. But the concept is well documented
