Any crystals that you think are cool and that more people should know about?

Sorry for the late reply (I'm busy traveling) but yes!!! I don't have ground breaking totally unknown crystals for you but from my collection I will tell talk about some fun little rocks.

Let's start with what is arguably my favourite crystal and it's a pretty underrated one;

iolite

Yes, that's where the Violet_Iolite username comes from (it's my username almost everywhere else besides here)

I have a polished and cut iolite which surprisingly might not be the most interesting form of this mineral. Iolite, or cordierite (the actual mineral name, iolite is the name used in the gem selling business) is a stone that depending on the side it can vary from a light yellow to a purple/blue. Mine is cut in a way where the blue is always the most visible but the sides have the slightest nod to the yellow. Some of the best raw forms will change between these two colours if you turn them around.

I will say the iolite names comes from the Greek ios, violet. So yes, my Minecraft username is something like Violet violet (stone).

Next I will talk about fake crystals versus lab grown ones...

When I say a fake crystals I mean crystals that are sold as other ones when that's not what they are.

Lab grown gems are different in the way that they are chemically the same as natural gems found in nature. In case of diamonds for example is much better for the environment (and in some cases for the health of the miners) if you get a lab grown one. However not all gems are possible to produce in a lab, sometimes they're more expensive to produce in the lab and in cases of quartz based gems the natural gems are so common it isn't worth it.

I'm mentioning this because of the next gems I will show.

Moonstone and sunstone.

Moonstones and sunstones are probably the gems that are most faked (turquoise too but at least turquoise is rare).

Moonstone is a type of light coloured stone (either white, sometimes pink) which has a very pretty blue glow (occasionally it gets a yellow one too) only in certain angles. Opaline (or opalite), a man made gem, is very commonly sold as moonstone however opaline is not even close to being moonstone. Opaline is translucent in a way moonstone isn't and it doesn't have the shine moonstone has. Opaline is a type of glass which commonly has dolomite and metal to make it the colour it is. It was actually made to copy opals so I don't really know why people try calling it moonstone.

Next is sunstone! Orange or brown in colour sunstone is not that special looking. If it's high-quality it will be more translucent and it might have some touches of sparkles but it's not usually something very strong. Our fake stone this time is Goldstone. Also a man made glass goldstone is made with copper.

There's a blue version of golstone which instead of having copper it has cobalt or manganese.

I have booth types of goldstone (the blue one is my favourite)

One that is moderately well known but it's absolutely cool anyway:

Alexandrite

One I recommend you buy lab grown or you'll waste all the money you have. Alexandrite is super cool because depending on the type of light you shine on it the colour will change completely. My alexandrite when in LED light (the light that most lamps have nowadays) or natural light is green. When under incandescent light (old lamps) it gets completely pink. If you lived only under incandescent light you'd believe it to be a pink stone.

When under both types of light:

Chalcopyrite (peacock)

Similar to pyrite but softer, with copper and and can tarnish with pretty colours chalcopyrite is a pretty cool metal. Wikipedia says it is "the most abundant copper ore mineral." So the copper you have in your cables is most likely from this mineral.

Chalcopyrite is in front and the pyrite (unfocused) is in the back of the picture.

Bismuth

I could've actually gotten an ok priced natural bismuth but I decided that getting a bigger sized would probably be better. This one might be lab grown. I'm not sure. The lady that sold me didn't know where it was from. It is 100% heat treated either way, as heating it gives it the lovely colours it has. It is a metal and according to Wikipedia it is "both the most diamagnetic element and one of the least thermally conductive metals known."

So... The last two are actually metal and not crystal but they are cool rocks so it's fine either way.

The silver consists of minerals of trpes of silver and [email protected]

The silver consists of minerals of trpes of silver and regeneration. Mostly associated silver mineral resources, therefore, the native silver minerals can be divided into independent and silver minerals of silver and lead, copper, zinc and other base metals associated by-product minerals of silver. And silver raw material source is more complex, mainly from the silver solid wastes (such as negotiable waste fake cartier jewelry residue, waste, etc.) and precious metal surface treatment of plating solution and fixing photographic industry recovery enhancement such as wastewater, etc. World silver mineral production are mainly concentrated in the silver resources relatively rich countries and regions, and regeneration of silver production mainly concentrated in some silver consumption power, such as the United States and other countries. At present, China, Peru, Mexico, Australia, Bolivia, Russia, Chile, the United States, Poland, kazakhstan is the world’s largest producer of ten taels of silver. According to the silver institute and the China nonferrous metals industry association of gold and silver branch of statistics, in 2009 the 10 national silver minerals produced 25275 tons, more than 80% of the total global silver mineral production. A characteristic, the silver production distribution is TongQianXin van cleef arpels replica jewelry basic metal production country such as China silver production mainly lead and zinc silver copper by-product mineral, and overseas main production silver silver minerals are independent silver, lead and zinc by-product, gold by-product situation of the three pillars of brass. International silver production and demand situation, the consumption of the silver The silver physical consumption is mainly from industrial manufacturing, photography, jewelry, silver and COINS seal statistics (excluding financial derivative silver investment demand). Traditional silver consumption photography because of the development of digital technology for silver demand is on the decline, but still occupies a certain proportion. Industry and consumption of silver jewelry industry in economic growth led by general growth, but greatly influenced by economic fluctuation cycle industrial demand. In recent years, silver objects and derivative investment demand in some countries such as China’s growth is rapid.

As the global economic recovery, to resume from industry industrial orders with the increase of silver, including electronic electrical and soldering material with silver has rebounded significantly, silver new applications such as solar photovoltaic cells with silver silver pulp to a huge increase in demand. Global demand for silver silver chapter in 2010, it is mainly due to the investment object of silver demand, American eagle, Canadian maple leaf and the Australian kookaburra silver has 50% sales growth, the Chinese market investment silver bar sales is also very hot.

But overall, the jewelry industry materials gradually diversified, concise, and result in the industry with silver amount will not be a new growth point. The future industrial application of silver in new areas will continue to focus on food processing, electronic and electrical, solder, catalyst, solar cells and water treatment, etc. Electronic electrical industry USES mainly reflects in the battery, switch, printed circuit board, silver paste, the compact disc (CD), plasma TV, etc. The good and evil people mixed up gold appraisal, it is well known that the gold market, fake gold.
