Sparkly eggs

My female Greek laid eggs this afternoon. A few of the eggs look like they have already chalked. I originally thought it was over calcified eggs but They are smooth as can be. Not deformed or bumpy. They are also very sparkly. my next hypothesis was that it was a previous nest, but she dropped 7 eggs and I dug up 7 eggs. Any body have any experience with having smooth, shinny & sparkly eggs that look like they have chalked already?

Smooth and shiny, yes. Sparkly and chalked over, no lol. Had to of been laid 30+ days ago is my guess...4 lookin good!! Good luck!!

Funny, I had pretty much the same issue with my Eastern Hermann's tortoise some months ago! 7 eggs, 3 of them strangely sparkly, like fresh snow. You can see them here. They ended up being unfertilized. Like you I wondered if they might have been from a previous nest that I didn't catch.
First time I've been seeing this, so I'd be very interested in an explanation, too.

So the sparkly eggs ended up being fertile. And hatched. I thought maybe they were from a previous clutch, but they hatched, all on time, literally within 60 days of being laid. I have no explanation as to why they were sparkly like snow. It's as if they came out chalked.

Oh my gosh, theyre gorgeous. That is all

Thank you!

Beautiful, beautiful babies!! @shellfreak It's great they all hatched.
I'm glad to see this post about the sparkly eggs. Nine weeks ago I found a Redfoot sparkly in a clutch of two. It never chalked but it's still in there cooking. I got another one this weekend. It took her a long time to get this one out and the one behind it was covered in extra calcification. Maybe it's a form of extra calcification? I have no idea.

Could be for sure. Keep us posted. Hopefully they are fertile.

Quick update: Looks like both the new eggs are fertile. But I think I need to either take the first sparkly egg out or at least separate it. It's been 70 days. I don't see any veining. Any thoughts?
