Featured Better Newer Costume Jewelry - Questions

I have been gathering up various bits of costume jewelry for a few months, and this lot contains some better, I hope, pieces. Some of them are not marked or I don't know the stone, so I have questions. Any comments or thoughts would be appreciated on the following:

1. Amber cross necklace with butterfly dangle. I checked it, and it is amber.




2. Green and blue stone earrings with sterling silver stamp. What do you think the stone is?



3. Rippled brown stone pendant. The surround looks silver to me but it is unmarked. What is the stone?



4. Is this as claimed: Ivory, Emeralds, Rubies and Gold Pendant.



5. Highly faceted stone - Quite small - Any thoughts as to stone?




There are two more, but ran out of picture space. See the next post please.

 

6. Ammonite? in silver - where did it come from?



7. What stone is this?

 

6 looks like nautilus shell.
7 leopardskin jasper on top

 

Excellent. Thank you very much!

 

I'll take a guess at the square stone in #7 - ocean jasper.

 

Thanks very much. That is very helpful.

 

@Hollyblue - what differences would a person look for between leopard skin & ocean jasper? Just for my own education. . .I have a couple of eBay pendants that were called 'ocean jasper'.

 

Ocean jasper has a lot of colors.

 

Thanks Hollyblue! Yep, my pendants are quite colorful.

 

3 maybe mahogany obsidian

 

Wow. I’ve heard of that! How wonderful

 

The blue stone might be blue topaz or blue zircon.

I posted a huge necklace a week or so back which had ocean jasper.

I've seen that butterfly dangle, I think there's something in the Hoard. The ammonite and earrings look like nice modern Indonesian/Balinese.

 

I was hoping blue topaz. I need to get a gem tester!
I'll look at your post for the ocean jasper necklace, though I study your posts pretty carefully.
I'm not going to keep the cross necklace. I just bought it, to see if it was amber. I was hoping to find the dangle, so I can know maker.
Excellent about the Indonesian/Balinese pieces. Although I don't have pierced ears, I was interested in these because of the stones and designs. The Nautilus ahell is large and so cool.
As always I appreciate your insights into what I have. Thank you so much.

 

This was the necklace: made by a South African artist.

 

4 is ivory. Don't think there's any way to know about the stones & metal from photos.

 

I remember this necklace well! I wouldn't have guessed this was the one you were talking about. Thanks for tracking it down.

 

Okay. Those were quick and dirty photos, as Riley was insisting on getting into the light box. A fight that went on for a half and hour. I'll take better this afternoon. I’ll lock her out of the room and not listen to the screaming. Thank you.

 

@KikoBlueEyes
I instantly thought, 'that a chip off the old mahogany block'; but I didn't have the chutzpah to say it out loud.

 

Brian. Perfect. Made me giggle. I knew I had heard of Mahogany Obsidian, actually I realized I have a chunk of it after @Hollyblue identified it.

 

Ammonites are fossils,you have a modern sea shell.
