I've found a rock and i don't Know what it is?

Question

It has a translusent honey couloured end with a sort of white crystal body please can you tell me what it is? thanks

Answer 1

Sure its a rock, not a mineral?

Can it be scratched with finger nail/knife?

Does it feel the right weight for its size?

Try comparing it to pics on a mineral/rock book.

Answer 2

From the information given, it is not possible to say what you have.

Where was it found? context is a big clue

This list contains information you can give to help identify

your specimen

Colour: (I'm English, we *do* spell it this way.)

Lustre: does it look metallic, glassy, pearly, resinous, or what?

Texture: Does it contain crystals, grains, size? are different crystal the same size or different? Fracture: If there is a freshly broken surface what does the fracture look like, What shapes are any crystals.

Density: does if feel 'heavy', 'light'?

Hardness: can you scratch it with a fingernail, a 'copper' coin, a

penknife, a file.

Streak: ? (No, put those clothes back on!) if you rub the sample on the back of an old ceramic tile does it leave a coloured streak?

The acid test: Does the rock react to a weak acid? (Toilet descaler works fine! -use carefully-) .

Answer 3

I use this all the time for identifying rocks:

http://emsc32.nysed.gov/osa/reftable/esp...

Go to pages 6-7

Once you find out if it's igneous, sedimentary or metamorphic, type in (rock type) gallery on google and match your rock up.

Could you help me with mine too?

Answer 4

Are you sure it is not dried out excrement from a horse with diarrhoea?

Answer 5

What's its Volume?

Archemedis principle

How many milli-gram(s) of water does it displace after getting submerged?

What's its mass in milligrams?

Calculate its density = Mass/Volume = (mg/cubic.cm)

Determine Density of glass

& other materials & stones

& then let us know

With which type of material, did it match closely?
