with regards to ruby, diamond, and other precious gem, mining the part I find enjoyable is most of these places are off the beaten path and a day spent in the country playing in the mud can be rewarding for lack of distractions of everyday life
As far as a cave that you can simply take an elevator down to and walk through on paved sidewalks, it is one of the best in the world. (There are also other portions for the more adventurous. Some that are completely underwater and require scuba gear.)
I think there are even places you can buy a bag of dirt to be shipped to you.
Another interesting thing you can do is buy unsorted/unwashed roman coins from europe. There are techniques to soak and reveal the face of the coins. Where else can you uncover 2000 year old human artifacts?
It's just a big field, plowed occasionally to turn up fresh dirt. Visitors look through the plowed dirt, looking for diamonds.
It's a unique place. Kind of fun, for the first half hour or so. (Then a little tedious.)
Is there a way to know ahead of time when they plow the field?
Also, I seem to recall that at least at one time there was a private individual who offered something similar to the park itself. Is that option still around?
But here's a tip-- they say if you go looking right after a rain, the dust is wetted down and the diamonds are easier to find. So they say, I can't say for myself.
Unfortunatly, that's a bit tricky if it's underground. Fun to bring to a gem show though.
Nope, diamond is 3.51g/cm³, some rocks are in the same density range.
> There are a ton of factors that go into appraising a diamond like the one that Hollingshead discovered, but it’s likely worth somewhere in the tens of thousands of dollars.
There is literally nothing interesting to talk about in this article.
Then marketing got involved. Now yellow diamonds are a thing. Dont fall for it.

I'd say the fact there there is not a glut of diamonds shows that they are actually pretty rare.
The idea that engagement rings "must" have a diamond only dates back to the '40s and is entirely down to De Beers' marketing. The same company spent a fortune promoting the idea that synthetic diamonds are somehow inferior and developing tests to distinguish them, even though they're chemically identical and the only way to tell them apart is that natural diamonds are lower-quality, with more flaws and less clarity.
It makes a pretty color?
Also, some of the most famous diamonds ever were yellow, including the Oppenheimer diamond.
