Does anyone else use gems?

I'm pretty sure energy isn't used in any type of refraction formulas I've dealt with so far. If I recall correctly, the phenomenon of refraction occurs when you have light coming from one medium with a certain refractive index heading into another medium with a different refractive index. More or less it should be Snell's Law from which I haven't observed any need to use potential or kinetic energy. Except for the speed of light on occasion.

Additionally pure light should be every single wavelength. When it passes visible objects, it specifically reflects off a specific wavelength of light that gives it the color that you see from the stone. Apparently even though this concept holds true for various biological systems such as choloroplasts within a plant (the chlorophyll reflects green light), gems don't completely reflect the color of choice (ex emeralds don't absorb everything but green light) otherwise they'd be way too dark in color. Therefore it's a mix of both reflection and refraction that give gems and crystals their definitive colors. Also most gems are inorganic in the sense that they have been discovered in lava faults or other types of extreme environment where they have formed along rock formations that existed for thousands of years. Organic gemstones are often regarded as gems that are obtained from previous living organisms that have died. Examples include coral, pearls, ivory, and amber. Even though a distinction is made between the two types, they are both regarded as nonliving inanimate objects by most scientists.

I worded my post wrong, and was very tired when I wrote it. I didn't exactly mean light refraction, it was just the first thing to pop up into my head about how to relate to energy. I really honestly don't know how scientifically a person reacting or 'healing' because of stones, can be shown, nor do I plan to show proof. I suppose I just figured it could be physically possible to show, and didn't really do too much research on it, sorta like the idea that one day we'll colonize the moon. If you don't get what I mean, I mean to say that I really have no scientific experience to back it up, so it may as well be me just being weird.

As for you, Quantact...I don't see how Gypsies have anything purely to do with the beliefs of gemstones. The greeks and other cultures also spread this around, and I'd rather not lump up one known group and turn it into, "Dirty, rotten thieves made bullshiet rumors to make money". This is a cultural difference that bothers you, and I do not want to promote any form of discrimination. The thing is, some herbs can be bullcrap too. Take all the new 'dietary' herbs in mind. While I appreciate your input on Eastern Medicine, I respectfully disagree and think that holding a few shiny stones isn't going to kill me.
