Another ugly rock?
In the continuation of minerals that cannot be seen with the naked eye, I have found others in our store that are interesting under the stereoscope.
The following are two diamond clusters.
The first is less than a centimeter wide. The second is about 3 centimeters. Diamonds are the hardest natural minerals known to man. They are pure carbon that were under extreme heat and pressure for thousands of years. Most people are unaware that diamonds are not found in single crystal form as we see them in the jewelry stores. Those are the result of hundreds of tons of rocks that are mined, sifted, and then sorted to find the ideal specimens for cutting and faceting.

To the naked eye these specimens look like ugly grey rocks with sparkles in them, but under the scope it's a whole different story.
On the larger cluster a small orange speck can be seen. So I had to check it out.
They say a diamond is a girl's best friend. If she only knew.
Diamond mohr scale, with hardness of 10, it is also use for cutting too
And what is the composition of the orange speck?
From the look of the structure, I believe it's calcite. But it's way too small to do any testing.
Very interesting and informative post!!! Thank you for sharing!!
