Identifying a rock?

Hi, i am new here and wouldnt be suprised if i was the youngist, i am 15 and have been colecting rocks for as long as i can remember. i really dont know if i will be on here that much or at all but i had to join to ask about this rock. before i get to describing it i should give a little backstory, back in the 4th grade i found this rock on the playground, i was digging it out for days and when i was finally getting it out this other kid "helped me" get it out, then stole the rock for himself and i have actually been trying to get it back ever since because i still want to know what it is i have only seen 2 rocks like it, and the other one went missing a long time ago. well anyway it was smooth and partially translucent pink rock with (from what i remember) some bits of yellow. i assume it was some variant of quartz but i dont know what, it was not rose quartz i can tell you that, it was more of a fleshy color then a full on pink, and it was not shinny, even though it was smooth it was kind of dull. i cant find anything like it on the internet and its really killing me, i dont know if anyone knows what this stuff is but if you do please respond.

Hi, and welcome to Geology

Hi, and welcome to Geology Rocks.   We really don't care about your age or experience.  We will help where we can.  In fact some of your phraseology beats quite a few adults we've had visit this site.

Now your rock.  Where are you?  If I'd dug a hole in the playground in SE London when I was a saucepan (Cockney rhyming slang --- Saucepan lid = kid)  I probably wouldn't be alive now to sit writing this!                                                              It is obviously very difficult to identify a rock by description alone. Again is it a rock or is it a mineral.  Rocks are made up of at least two minerals, and yours sounds like just one pinkish colour in the main, indicating a single mineral.   It could be rose quartz, and the yellow is 'rust' from some iron mineral adjacent to it, perhaps geothite. That is not uncommon.  Do you know its hardness?  Relative density?  Where are you?  Does the local geology support such a find?

You will have to do some tests to find these things out and if possible post a picture of it for us.  I realise that might be a little difficult.....particularly if he is bigger than you!

thank you for responding, i

thank you for responding, i live on the east cost of the USA. i bealeve it was a minerall, i tend to use the word "rock" as a general term, sorry about that lol i can confirm that it wasnt "geothite" and it was about the same hardness of quartz, possibly a little denser. i dont think the yellow bits were iron, they seemed to (again from what i remember, its been a while) blend seemlesly into the rest of it, so i think it was all the same substance.

Sounds like amethyst and citrine

 It sounds to me like you found amethyst and/or citrine quartz varieties. Google : rough amethyst and citrine images and see if the images remind you of the stone that you found way back when.

Nope its also it was

Nope its also it was rounded, from weathering and erosian. so i feel like it might be even harder to figure it out because pictures on the internet of any type of crystal will show up as nicely formed crystals, and not what this was.

Unfortunately pictures in

Unfortunately pictures in books and internet images tend to show the 'perfect' crystal.

I didn't mean that this was geothite, simply that the yellow (which I took to be staining) might be caused by geothite.

We really need more information on this and a picture.  It could be one of many things.

Interestingly enough....

Coincidentally, I came to this forum hoping to figure out what kind of rock/mineral I found, also in fourth grade and is also pink! I am 29 now, I have had this for quite awhile! I found it walking along the street in Santa Ana (southern CA), it was quite rough and dull on the surface, but I picked it up, and to my delight was quite smooth, cool and glassy.

Sorry these pics are so big

Sorry these pics are so big and blurry.... Every time I tried to change the dimensions, they wouldn't attach.  If a flash is needed I can do that as well.

Feldspar?

My guess is feldspar, Tindra.

Anyone else agree?

Sorry for not responding in

Sorry for not responding in a while, and wow that is a big coincidence lol although unfortunately that is not the same kind of rock I had :( 

i am also doing my best to get the rock back or at least pictures, with luck i will be able to do that soon.

I have to say that from

I have to say that from those huge blurry pictures it looks a bit like rhodenite.
