Baltic amber has a hardness of 2-2.5 (soft). See if it will scratch a shiny penny from the 70s which has a hardness of 3. If it does, it is not amber.

From the pics I see you have or have access to a digital scale. Here is a simple test you can do, that will supply more useful information for IDing minerals:

1) weigh a mineral by itself on the scale and record the minerals weight

2) place a cup of water on the scale. The cup should be large enough to place the mineral in without touching the sides or bottom of the cup & without the water flowing out of the cup; now zero the scale with the cup of water on it

3) using some sewing string, looped the string around the mineral, place the mineral in the cup of water (still on the zeroed scale), by the string, making sure the mineral is completely under water and not touching the sides or bottom of the cup. Record the scales reading

4) repeat set 3, 2 or 3 times being sure to place the sample at the same water depth each time; this is to see that your reading is consistent

5) divide the mineral's weight (step 1) by the minerals weight in the water (step 3); write this number down

now you have what is called the minerals "specific gravity" This specific gravity # is very useful in pinning down a minerals ID

This does not help when IDing rocks, only minerals

Here is a you tube video on how to do this: https://www.youtube.com/watch?v=_AxFNtV15vE&spfreload=10

does it feel like a very light rock? Amber feels feather like and is very light.

Amber has a specific gravity of 1 to 1.5, so your sample is not amber, but you have a needed piece of information, a specific gravity of 2.67. That's great!

Now find out the approximate hardness of the mineral, like you did for the corundum sample.

Question: in pic # 12 (counting left to right), I see what looks like striations (parralllel lines) on the mineral. Did you clean the mineral with a metal brush?
