Amber is 2-3 on the mohs scale of hardness.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
Quartz has a hardness of 7 on the Mohs scale, making it relatively hard and durable.
This scale was proposed by the Austrian geologist Friderich Mohs.
It's called the Ore
"Andesite" is a rock type not a mineral (it is made of a mixture of minerals). Mohs scale relates the hardness of individual MINERALS not ROCK TYPES and thus your question can not be answered.
Amber is a relatively soft material, ranking 2 to 2.5 on the Mohs scale of mineral hardness. This means it can be easily scratched by harder materials.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.

Quartz has a hardness of 7 on the Mohs scale, making it relatively hard and durable.
On the Mohs scale, 6.5 to 7.0.

The hardness of uranium is 6 on the Mohs scale; not so hard.
Iodine is not recognized as a mineral, and therefore is not assigned a number on the Mohs Scale of mineral hardness.
It is about 2.5 in the Mohs Hardness Scale.
