In response to Wjfox's most recent status update.

I decided to do some sleuthing and realized that was the one who posted images of gemstones, but that was for a deeply off-topic thread about a story I was trying to muster the energy to write at the time.

Here's two of my favorite gemstones: the fire opal

It's like a sunset you can hold.

 

And the rainbow opal
Actually, no, it's called a Boulder Opal

Though actual rainbow opals aren't half bad either

 

 

 

Another fun one has to be the bismuth fractal crystal,  an artificial crystal grown from molten metal

Painite is a very rare borate mineral. In fact, perhaps the single rarest mineral on Earth

102-carat 'flawless' Canadian diamond sells for online record of $15.7M US at auction

Oct 05, 2020 12:08 PM ET

A diamond unearthed in Northern Ontario two years ago has sold for a record price in an online auction, to an unnamed buyer who paid $15.7 million for the flawless, colourless gem.

The stone, which was cut from a 271-carat rough diamond found in the now-closed Victor Mine in Northern Ontario in 2018, was highly touted for its D colour and flawless status, which means it is considered to be as close to a perfect, naturally occurring diamond as is possible.

Less than one per cent of all naturally occurring diamonds in the world achieve the stone's lack of impurities and colour — and there are only seven that are as big as it is that have ever come up for auction.

Could all of these gems and crystals be manufactured with the right technology, or are some impossible to make outside of a natural process?

If we can already (as of 2020) simulate conditions around Earth's core (see e.g. room-temperature superconductors), then I expect we'll have machines that can synthesise pretty much anything within the next century or so. Though whether there's an economic demand/need for such artificial gems is another question.

Kernowite: New mineral found on rock mined in Cornwall

9 hours ago

An "amazing" new type of mineral has been discovered by scientists analysing a rock mined in Cornwall about 220 years ago.

The dark green mineral has been named kernowite after Kernow, the Cornish language word for Cornwall.

A group led by Natural History Museum (NHM) mineralogist Mike Rumsey made the discovery while studying a rock taken from Wheal Gorland mine in St Day.

Mr Rumsey said: "It's amazing that in 2020 we are adding a new mineral."
