probably the last pic thats any good.

Hi Birdie.....You could try taking a picture of your specimen through your loupe or a regular magnifying glass. Hold the camera right up against the loupe or mag, zoom it all the way in and use Macro setting if you have it, then move cam and loupe together until the image is in focus in the view screen and take the pic. Make sure your flash is off and use an external light source. You can do this through the eye piece of your microscope too but you will have to do some playing with it no matter what method you use. You will be surprised at what a 10x loupe will do for the magnification on your pictures....have fun with it....Andy

I don't know what it is but I once found something similar in quartz, though mine was too small to keep or photograph.

I likened it to this one - (Which is NOT one of mine) - http://www.mindat.org/gallery.php?min=3407 -- ID 115099

Rhodonite ??????????

A wild guess: Almandine garnet ?

Rock Currier would say this is grape jelly. A significantly better picture (closer, and in focus) is necessary before any definitive guess can be made.

Without x-ray eyeballs you can't sort out the garnets!!! But I'll bet Knut is right.

well guys, thanks so much for your input. personally i believe my specimens are "eudialyte". done more research and it seems right to me. i got the answer from someone in chat. thanks so much for that.

i am new to hounding and have come a long way in a short time. what a interesting and educational experience thus far.

have gathered some pretty unique specimens so far.

they include

a natural native quartz crystal cluster, needs cleaning but a nice sample - aprox 9.5cm x 9.5cm. mixture of milky to transparent with clear natural facets. quite vistrious, reflective and refractive in light.

some boitite and muscovite

fair bit of pyrite,

some sharde of eudialyte,

my wife has some nice purple amethyst as well.

time is tickn' and snow will soon fly, so my prospecting days are limited. i'm already thinking about getting in a lot more time next year.

so take care out there and best of luck in your ventures.

talk again soon, will post new developments.

If it was found in quartz, it is very unlikely to be eudialyte: that occurs almost exclusively in undersaturated alkaline rocks, which are almost invariably quartz-free.

Hi Peter,

you forgot about alkaline agpaitic granites and syenites with their pegmatites. Eudialyte able to form in quartz associations - http://www.mindat.org/photo-70382.html, http://www.mindat.org/photo-176411.html etc.;)

Of course in such associations biotite is absolutely restricted, other alkaline minerals grow here instead of it - aegirine, arfvedsonite, aenigmatite, neptunite etc.

Check the hardness!!!!

Hello Birdie,

Never heard of eudialyte from that neck of the woods, where exactly did you find it?
