This is the best topic ever!!!!! 1st, I collect mineral specimens and have gorgeous gemstones. This sounds ridiculous, but my all time favorite stone is pyrite, also known as fools gold. The reason is because it’s crystal structure is cubic, perfect cubes growing within another cube. I have a giant 2.5 inch cubic flawless pyrite with sharp edges. So amazing. I have pyrite necklaces and have about 20 different pyrite specimens. Sometimes the cubes are flattened naturally in mine on black slate and it looks like a golden flower. Pyrite is so amazing despite the funny name of fools gold, because many times it’s golden and shiny looking like gold. The best pyrite cubes are found in Spain, the same region in Spain my ancestors are from.
There are so many types of stones I love though. Lapis Lazuli has beautiful deep blues which are so therapeutic to look at. It grows often with pyrite, giving golden flakes in beautiful deep blue.
Opals are awesome reflecting so many different colors because it’s chemical formula is silica with H2O.
I have the most beautiful large Citrine gemstone. The orange color will put you in a trans.
I can go on and on. Galena is another I love. It’s cubic properties are similar to pyrite, but shiny silver instead. Galena is made from lead.
