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...

The Mountain Jade Lapis in that link looks a little close.

Thank you so much George, Robert & Don for your opinions.

Robert that's a great link, great info.

I did know lab grown gems were first manufactured in the late 1800's. Not that I'm able to distinguish between natural & lab gems, & I suspect the jeweler I use employs the eeny meeny miny moe method:)  Based upon info provided in the link I'm guessing much of the lapis I see is manufactured.

I very much appreciate all of your time!

Lapis with a lot of calcite has been dyed forever.  That is what the blue stones look like to me.  It is possible that the pale stone was dyed originally and somehow was washed with a solvent.  The setting being very nice and very old, you might consider replacing the stones with better quality material.  Lapis is easy to work and in small quantity it won't cost very much.  If you can't find a decent slab, let me know.

Thank you! If I decide to replace the stones with the real thing I'll certainly reach out. I appreciate your kind offer to help. Nancy
