Featured Not my wheelhouse - Jewelry and stones

So I have been given the fun task of cataloging over 200 + pieces of Navajo, Mexican, etc jewelry from a client for an upcoming Valentine's auction. I am figuring out some pieces of agate and gemstones but need help on a couple of pieces. Most are marked Sterling or 925 and the unmarked pieces, I have tested for silver purity. Here are a couple that I am struggling with - I am not sure of the main stones/agate in these pieces but know moonstone, lapis, amethyst, etc Thanks so much for your kind assistance.

 

I see a lot of labradorite, some blue topaz, peridot.

 

I processed some labradorite yesterday but it was highly polished - is that what the 'rainbow' color stones are in the first picture? Those have me stumped. Thank you!

 

The large stones in the pieces in the first pic. remind me of the man-made "stone" called rainbow calsilica. I saw a bunch of jewelry made with it in catalogs (like Coldwater Creek) in the early 2000's.

 

The main stones in the first 2 are something in the agate/jasper family. The colors, particularly on the right, do not strike me as naturally occurring in bands like that, but the world of minerals is wide, so... The round cabs on that one look like labradorite.

The bracelet looks like MOP to me, & then a selection of labradorite pendants.

 

Yes, good thought. I've seen it too but not one that readily comes to mind.

 

rainbow calsilica! Yep just did a search and that makes sense. Thank you! Does MOP often reflect some blues?

 

Labradorite in the second last. I wonder if the first might be iron stromatolite?

It can, but meant to ask if photos are picking up the full range of color on that one. I'm less confident there than on others. MOS may be correct that it is pale lab.

 

The first two pendants are in the style of older Sajen pieces, but not quite Sajen. And not marked as such.
The jewellery so far looks Indian, although I am not sure they ever used rainbow calsilica in India. It is a positive for rainbow calsilica btw.

 

Spectrolite, amethyst, moonstone (with the rainbow calsilica piece on the right), peridote (the green ones) and possible blue topaz too.

 

yep already figured those out with my gem tester. Thanks you! Never heard of Spectrolite but I see it is used to describe labradorite as well.

 

Labradorite is a certain type of spectrolite.

 

I've some very similar pendants - modern, those are, but nice. @Any Jewelry - some of mine came from Indonesia.

 

I considered that, the style is certainly Indonesian, that is also where Sajen jewellery was first made. But the Indonesian ones are usually made with more attention to detail. For instance, you will probably notice a difference between the backs of these pendants and the backs on yours. I expect yours to be more symmetrical.

 

I shall go look!

 

So this collection came from an old gemologist who traveled around the world and is is apparently well known in that field. She and her husband spent a lot of time at the old Native American trading posts. They had an extensive amount of pottery from different tribes. She traded a lot of her precious and semi precious stones for things at the trading posts. She had a lot of Mexican jewelry and pottery along with Peruvian. They had a lot of mine cut opals, etc. One was 190 carats. Her husband is very sick so she dropped off everything to me and pretty much told me to figure it out. Thanks so much for the help!

 

Looking forward to the other items, laura.

 

Here was a photo of me trying to sort pieces out - I decided I needed a bigger table as these pieces were only what was on top in the box. The rings were close to 100. Lots of pretty eye candy rhodochrosite, spiny oyster shell (red, orange, purple), sugilite, labradorite etc. Way over my head as I am not a jewelry person. When hubby wants to buy me a pretty bauble, I always tell him just to spend that money on our horses or dogs. Starting to change my mind now LOL!

 

So the bracelet is a hard stone - definitely not MOP. I am wondering if the stones could be a turquoise? Some thing like Orvil Jack?
