Stongest materials

Recently, I was looking at a top ten of the strongest materials on earth on YouTube: https://www.youtube.com/watch?v=4Aprrlqd-TU
I find it very incredible.  There is the usual diamond.  I knew that,  It is one of the strongest gems known to us,  It can break if it hit on one of it's cleavage but it is an hard stone anyway.

I also found a video on the top ten rarest gemstone:

Again, there are diamonds there.  Nothing to surprising that diamonds are on both. 

Here are the top ten most expensive gems of all time.   Pretty much as the above list.

With this list, I fell a bit of a repeat.

My point with these lists?  There are some of those gems and materials I would like to work with  Would be great, just for the experience of it.  Do I have enough experience to work with them?  For sure I haven't have enough experience.  I feel a bit of a starter in jewelry making.  There is so much to learn and practice.  I haven't have all the tools to makes fine jewelry.  I can dream about those nice gems.  I like rocks and gems.  I don't like all gems nor all rocks.  But there is many of them that I love.  I like obsidian and lapis lazuli.  Emerald and peridot too.  Sparkling opal and nice aquamarine.  I would like to work more with them, on a professional level.  I hope to attain my dreams one day...
