Featured 14k pendant, mosaic, some kind of opal?

Anyone able to tell me if this is opal? it’s a large pendant @ 1-5/8” x 1-1/4”. Sorry for the trees reflecting on it, best I could do at the moment.

 

I guess glass but that's just a guess... is the setting gold? Whatever it is it's gorgeous.

Edit stupid me I just saw the title says 14k.

 

Does it have an open back,if it does what does it look like? The edges between the pieces are flaked pretty bad and I don't think even an opal mosaic in gold should look that way.

 

Maybe lab opal pieced together? Like Holly, interested in seeing the back.

 

It’s open at the back, I’ll have to get a shot of the back tomorrow, I found it at the cottage I bought to renovate and rent, it isn’t with me at the moment.

 

Here’s a shot of the mark, for what it’s worth.

 

Hmmm... it looks like glass to me due to the chipping on the facets....even though it is 14k.

 

looks like a shopping channel labradorite pendant......

 

This looks to be lab opal that was broken into pieces and then put back together, true mosaic opal designs are different pieces of opal that have been cut and shaped to fit together, or remaining pieces of opal that are either too small to set into a single pendant...

 

That's what I was thinking too: a single slab deliberately fractured. Can imagine it could be done with little chisel taps, without having to put it back together, but leaving those little chips at the edges.

 

I've broken glass to get a random background for an art piece.

I don't know how different it is to work with opal, but if that's smashery, well done.

Although, the hexagon is just showing off.

 

Not a created opal pattern...

I agree, ammolite mosaic. And the flakes look very much like stone to me, not glass.
The Aussies do make opal mosaic jewellery, but I've never seen that mounted in 14k gold.

'Reds and greens are the most commonly seen colors, owing to the greater fragility of the finer layers responsible for the blues.'

OP's is very blue-dominant.

'So-called "frost shattering" is common; exposed to the elements and compressed by sediments, the thin ammolite tends to crack and flake; prolonged exposure to sunlight can also lead to bleaching. The cracking results in a tessellated appearance, sometimes described as a "dragon skin" or "stained glass window" pattern.'



OP's clearly was deliberately fractured. Maker may have intended an ammolite appearance; I'm not at all convinced it is ammolite.

 

Thanks everyone, I’ll try for better photos today and post them when I get back.

Still think it is ammolite "puzzle/jig saw"

 

It's not that ammolite can't show blue; it's that it would be a highly unusual specimen that was predominantly blue with so little in the red-orange range. Can't imagine you would fracture such a rarity.

How's Vienna?

 

I think it is made from small leftovers, not one only crushed piece

Vienna is... HOT

 

I gather that is not the good 'hot'.
Buy yourself a nice handfan.

 

ammolite is what I was thinking when I wrote Labradorite......
all those -ites get me confused !!
