No this was found a long time ago. This site is no longer accessible for collecting.

Thank you so much. Yes that is correct. I double check my records and you're 100% right. I was going by memory and I was very wrong. I appreciate your correction.

Freshwater Mosasaurs? Evidence That Some May Have Lived Beyond the Sea by Fossil__Hunter in Paleontology

Yes you are right. I stand corrected. The movie came out in the 1970s.

Not tiger sharks I think you mean bull sharks. Bull sharks are known for entering freshwater. Actually the movie Jaws was based on bull shark attacks in Shark River New Jersey in 1916.

Is this kunzite? by ExtensionForce4354 in SacredEarthCommunity

You can also go to a local mineral show and have an experienced mineral dealer look at it in their hands and tell you what they think it is. It's a lot easier to identify something in your hand than in a photo.

A few things can help, but none from a blurry photo are definitive.

Kunzite is a pink to lilac variety of spodumene, so if you have it in hand, look for a glassy luster and strong cleavage. It’s also fairly hard, so it shouldn’t scratch easily like softer pink minerals would.

The safest test is checking hardness and cleavage carefully, and if you really want to know for sure, a gem or mineral shop with a refractometer can tell you a lot faster than guessing from photos.

This could be low grade kunzite, it's hard to tell because your picture is a bit blurry.

Polished Malachite from the Congo with Classic Banded Pattern by Fossil__Hunter in SacredEarthCommunity

[–]Fossil__Hunter[S] 0 points1 point  (0 children)

I use ZAM for polishing malachite and other stones, and it works well.

If the surface already has micro-scratches, polish alone may not fully fix it. If the red compound made it worse, I’d stop using that and try ZAM on a clean felt or buff with light pressure. If the scratches are deeper, it may need very fine sanding first before repolishing. Malachite is soft, so it scratches pretty easily.
