Hi All, New here, thank you for accepting me into your forum!

Confused by the coloration of the large bottom cabochon on this necklace, mottled pale greens & blues on front, darker lapis blue on back. The other cabs are lapis. Any opinions welcomed & thanks for looking:)

If in fact these stones are lapis, I am guessing that the creator for this necklace did not like the look for the blue side of the larger cab. Neither do I..

So he/she decided to flip it around and use the side that has the much higher content of calcite.  I think it was a good choice..

With that said, I am not 100% sure that any are lapis, but am not able to give an ID.

Can I see much closer pics of one of the three smaller ones, and also a front one for the largest cab.

Hi Nancy and welcome

I have seen lapis look like the 3 blue ones but I have not seen lapis look like the pale green.  Not saying it's not possible, just saying I haven't seen any.  Usually your high end lapis will have very little calcite and perhaps some pyrite (I like the pyrite).

Hope this helps and nice necklace too - is it an antique?

Now that I can see the close ups, I am with Robert and accept his comment from his experience about having seen similar looking lapis..

But I can not say that I have seen a similar lapis, and can not offer a second candidate  dunno

Can't say for sure. just a gut feeling that something is off. I've handled a lot of lapis over the years...these are setting off my spidey senses.

Hi, Yes it is antique, 1920's or thereabouts. If a stone were manufactured would they go to the trouble to make front & back so different? Thanks again. Nancy

Me too. I also have handled a fair amount of lapis and something about these stones, even the blue ones, doesn’t look right.  I think they might be reconstituted.

I could be wrong, I was assuming that being an antique, it was too early for the fakes but according to an article (see link) good fakes started in the 1870s.  Hope this helps...
