Accidentally purchased jadeite stone turned into pendants

[PavelF]

So, i never worked with jadeite before and have little to none knowledge about what colors are popular and so on.
(i know about imperial green and other top notch jadeite's but nothing about more simpler coloration)

However, i was like digging through random stuff at stone fair and whoosh, this jadeite boulder was in the middle and the seller was more than liberal about pricing.



And here are the stuff i made from it. What do you think?






Any honest opinion and all sorts of basic information are welcomed.

Thank you for your attention.

What is the stone in the second photo？

What is the stone in the second photo？

Jadeite. All three pendants originates from the boulder on the 1st photo, which change its color from blue on top to murky something at the botom.

The boulder was scratched, checked by spectrometer and observed under a microscope. Jadeite it is.

Thanks for your reply. May I ask what is the model of the mircoscope you are using?

I am not that intellectual type of a man.
There is a special booth at stone fair where certified specialist is sitting to provide expertise needed to those who in doubt. I visited it for consultation.
And, my friend is literally tutoring in State geological university. He said that this is good stone.

I see. Thank you

My good sir; may i be enriched by the thinking process you have chosen to conceal?

I am still doing the research on the mircoscope. But 40x magnification is the minimal.

I would have guessed banded onyx

The pendants are beautifully shaped, really lovely pieces.

 

[Bluegemz]

My guess would be nephrite jade. Lovely pieces

 

[Burmesedaze]

Looks more like nephrite if they are jade, lovely.

I don't like to push this discussion away from jadeite's coloration, BUT, i can't help but to post this. 100% nephrite which mutilated my believe in my ability to distinguish nephrite from onyx ))

Beautiful treatment of the stone!

 

[stracci2000]

Sleek, modern design. Very nice!

Those are pretty. I love the creamy color. Does it swing a little celadon IRL, or is it more yellowy white? They look like dendritic agate to me. I thought nephrite too at first, but after looking closer at the pics realized I don't think I have seen nephrite with strong red like that.

Do the black inclusions look like dendrites up close? How's your SG coming in as? I know you just picked it up, but do you know the country of origin?

I've done my best to make sure that colors on photos are correct and not in any way are appearing more contrast or bright than in real life. It is safe to say that creamy one do not give any yellow shades no matter how you look at it. Vivid blue layer on top of the boulder was only few millimeters deep thou.

As for inclusions, i think they are more "sharpy" than dendrites. I will try to make several macro photos of them tomorrow so everyone may have a closer look.

I described the process of this stone verification at the 3d message in this thread. If you do suggest that i shall go through additional tests i will. However, it is the middle of the holiday season and were i have pendants with me i am away from any work related instruments for a time being.

The original owner of this stone was a jewelry maker who is long dead. He had an access to the materials brought from all corners of Earth. This stone was among the assorted boulders his widow gathered from an attic or something.

Did i missed more diamonds in the rough is the question which will remained unanswered.

Not a pretty closeups but that's the best i could do )

For what this isn't worth as an ID:

The colours and pattern of inclusions make me think of opal not nephrite (although I can imagine examples of each that would be perfectly confusing in a photo too...).

The opals without play of light are less known as jewelry materials, with one exception: a white variety ('Cacholong') that Canel has famously put to use - recognizing the obvious beauty of its fine grain.

Your piece has more interesting pastel colours that nephrite does not quite do: pale blue is impossible; the greenish 'celadon' shades are possible in both - and are classically valued in finely grained nephrite second only to white & with their own tradition...

Just a thought (I could well be wrong with the ID)

 

[PavelF]

Oh, i have several of those Cacholongs, was thinking to make wall decorations from them.



I am sincerely grateful for your opinion. I seems that i shall go through all tests once again (probably including the one with acid) and do more research about colors popularity before putting a price tag on these pendants.

Ok. update.

the drop of 38% HCL is doing nothing on top of the pendants.
with hardness between 6 and 7 and sg somewhat 2.6 2.7 (hopefully i managed to measure it correctly)
i am starting to think this is chalcedony

I am terribly sorry for stating that this is jadeite. Sometimes stones are fake, sometimes it is fake professional gemologist.

Since your stone has a flat surface, you can do a RI test on the stone.
