7 lb diamond?

[Caleb12]

Big as my fist. Eats sandpaper. Weighs almost 7 lbs considering the fact that I can still hold in the palm of my hand. I'm going to go to a jeweler to have them checked out along with the others. Will update.

Aluminum of silicon carbide sandpaper must be used.

Used 150 grit 3m wet or dry alum sil carbide sandpaper. No scratches at all. Was even less resistant as in the glide across the surface than the sandpaper before which was 100 grit.

Honestly, I WOULD NOT GO TO A JEWELER IF it was a diamond that large. I would keep my mouth shut so as not to have anyone learn about it and subsequently break into my house or worse.

I would get my hands on a sapphire or ruby first to perform a scratch test.

Also moissanite is rarer than diamonds and SOMETIMES harder...very valuable!!!

At that size I would want to keep everything very low key! Please keep us posted!

Unless I am mistaken, Moissanite is man made.

It kinda looks like quartz to me. Get corundum to do hardness test.

 

[Jim in Idaho]

Dip it in a tub of water. If the surface is wet when you pull it out, it's probably not a diamond. I agree with EU...probably quartz.

I would say definitely not a diamond, sorry . It looks like quartz from the picture , could be topaz , beryl or something but probably quartz .

Yes Moissanite is mostly artificial , it does actually occur in nature in meteorites and rare conditions but , very small , I have never heard of it naturally occuring in anything even close to that size . Anyone familiar with gems and minerals should be able to identify it in person. Good luck

 

[thehunter123]

Honestly, no tests really needed here. This is quartz.

 

[ecmjamsit]

Quartz of milk.

 

[Ponchosportal]

Yes it is quartz.

 

[Kray Gelder]

To everybody. Stop with the picture id-in. You can not id rocks positively from a picture!
It has no crystal shape for you to judge the compound of the specimen. He did the scratch test.
More than half of the people fail to do the scratch test properly on harder materials and 90% of random finds that get put in the SEM are industrial glass.
Yes, it is quite possible that he did not do the scratch test properly. But you, me or anybody else cannot know that.

So, encourage Caleb12 unnecessarily, that a piece of rotten quartz MAY be a diamond? Let's go with the odds, then. How many fist-sized diamonds have you heard of or seen? I could take you to several places in the Cascades where entire hillsides are made up of these possible diamonds.

Nope, but it can be.

Moissanite can definitely be man made...Due to rarity of it there is lots of incentive.

Typically it is 9.25 on the Mohs hardness scale according to the USGS, but some diamonds can be scratched by it.

However, statisically a rock this size should not be diamond or moissanite...but would be insanely valuable if it was.

Just curious if a UV test was done yet.

"I could take you to several places in the Cascades where entire hillsides are made up of these possible diamonds".
You would not believe how many valuable finds from gemstones to ore deposits were obscured by similarly looking "ordinary" rocks and minerals.

I would not believe. You must possess unbelievable information and knowledge. The OP is talking about diamonds. That rock has no hope of being a diamond.

It has iron staining, it is not a diamond.

 

[IAMZIM]

I should probably be more specific. Diamonds "wick" water. Iron staining is caused from hydrothermal activity. Diamonds cannot "stain" because of their water wicking properties. Even broken surfaces on diamonds (and yes, diamonds can break) will wick water. They can have inclusions, but not staining after the fact of them forming. Where diamonds are formed, it is too hot for water not to be evaporated as well. I hope this helps!

I happen To have a couple pieces of corondum. Thanks. Quartz doesn't frack and crack with perfect cleavage.

 

[Caleb12]

Do diamonds not have a yellow tint? I believe they do.

 

[Caleb12]

I happen to have a couple pieces of corondum. Certain color? Blue, red, orange?

 

[Caleb12]

It scatches it alright. The corondum that is. ReAL big nice gauge on it.
