What was the date the first diamonds were mined?
It's possible that diamonds were discovered in India as long ago as 6,000 years. Without documentation, it might be difficult to settle on a precise year in which diamonds were first mined.

How long does Topaz last?

How do you tell between topaz and quartz?
To distinguish topaz from glass or quartzes (e.g. citrine), we should observe the hardness. Topaz is a fairly hard gemstone, meaning it is resistant to scratching. It is 8 on the Mohs hardness scale (diamond is 10, sapphire is 9). A scratch test will determine whether a stone is topaz in most cases. You can perform a scratch test by taking a piece of quartz or other material with a hardness around 7 and scratch it against the "topaz". If you don't want to risk the stone scratching, even if it's fake, you can choose to scratch it on the girdle (the unpolished rim around the gem).
