Is this quartz?

Hi,
I found this beauty in north east africa. Can anyone tell me what it COULD Be.

If you can, get it checked.
There are many alluvial stones, generelly those who are quite hard.
Just by 'look' you can have a hard to ID stones which have lost their natural shape. (E.g rounded)

Get specific gravity if you can.
A local school, if they have a lab should be able to help. (a scale is needed)
Then you:

Notice dry weight
and submerge it in water and notice wet weight
Then you use this formula:

dry weight/ (dry weight - wet weight) = SG (Specific gravity)

Thank you! I will do so!

Here are some more pretties I found

Could be quite a few things, most likely quartz, or maybe topaz. Both could become that rounded in a stream. I would perform some hardness tests.

that can eiter be amber or a diamond

i have what i believe to be topaz that looks like the first pic. could also be quartz or possibly golden or yellow citrine.
