Featured Is This Wee Pitcher Mutton-Fat Nephrite, or Jadeite?

Please note the grecian key border, which surrounds the rim.
~92 grams, 4" long, 1 1/2" high at the pouring lip, 1 7/8" wide; the bore of the grip is ~12mm.
It is quite hard enough to resist a good steel point, and highly polished on all surfaces. I want to believe it has some age to it...but that cylindrical bore gives me caution there.
Virtually all I know about jade is stated in the title; two types, jadeite being slightly harder than nephrite, and usually more green than white or yellow.
Your wisdom and comments are welcome as sunshine!
Thanks for lookin'...

 

Found this: https://www.sothebys.com/en/buy/auc...n-archaistic-jade-handled-cup-yi-ming-dynasty

And this: https://www.christies.com/lot/lot-6...k&intObjectID=6306012&from=salessummary&lid=1

Neither have grecian key rim, and both have a different foot profile, not to mention more color.
Mine is, then, probably a modern reproduction.
Should I seek an evaluation, or an appraisal?

 

Whit-Couldn't hurt to bounce it off some online archaic Chinese art forums,get some educated guesses,and if some pos feedback-then take it to an expert. Who knows-someone with 40 years of experience might (?) be willing to share a little wisdom gratis.
Anything poss worth a grand and up-would most likely need eyes on examination I'd think.

 

It is gorgeous, and mutton fat nephrite. It is antique imo, but don't know if it is Song, Yuan, Ming, or Qing, just that the jade looks to have proper age.

Nephrite is the traditional Chinese jade, and highly valued by collectors. Nephrite can be any shade of green, but also reddish, brown, russet (rust colour), yellowish and white.
Jadeite jade is imported, mostly from Burma, and it can come in just about any colour. It became popular during the Qing dynasty, with the economic rise of the merchant class.

 

These corners, where the lines overshoot, look to me like they have been cut with power tools:

 

Thanks, AJ...I've posted it on https://asianart.com/phpforum/index.php
but they review all new posts, so it may not appear for a day or so. Also, they only allow 3 pics at a time, so it's only partially illustrated there.
MOS (good work, Eagle Eye!) has opened a can o' worms with the super close-up that shows what may be the incontrovertible proof against the antiquity I had hoped for. Sigh...
No matter, really...it is lovely an' sweet in the hand. I have another piece, a small dark green cup (jadeite?) that is high-probable fairly modern. I'll post it in Jewelry, soon as I take some pics...

 

I'm also a member there. They are good when it comes to Chinese art.

 

Y'know, I have looked for a sign-up page, without success. Is membership by invitation, or is there another way to become a member? I would like to do that, if possible. Thank you!

 

Oops, I was thinking of another forum, sorry about that.
This is the one where I contributed a couple of times, mostly to identify Indonesian items. Twice even European items.
I think I lost interest because you can't log in, you have to go through a long process only to help someone, and rarely get a response.

 

I'm not sure they have members per se. You submit stuff for review, and whoever is running the site decides whether the material is appropriate.

 

That means it's a curated Site-interesting.I wonder what the basic criteria is ?

 

It looks like you have a reply there already!
I have used that forum too, and got excellent info about my Japanese prints.

 

Yeah, you just submit a question with a photo, and in a day or two, someone will give you an informed answer.

 

That's my take...I have had several really helpful responses from the site. I'm glad to have access!

 

There are apparently two, bosco: China & Japan, and Southeast Asia. I haven't had opportunity to use SE Asia yet.

 

Looks like a very good translation site-good luck on finding out more about your pitcher.

 

Many sites are. Antiquers is one of the few antiques sites I've come across that isn't.

The person on AsianArt said late Qing, which sounds fine to me. There could be more replies later on.

 

Antiquers has no 'Gatekeeper' curating who/what gets on the Site-and yet most items aren't inane rubbish & are intriguing,& for the most part are 'teach-worthy' (weird phrasing).
As a amateur who picked solely for pleasure for years,I never spent much time researching my items (and online sites years past were scarce).
When you come here you have a group of folks who've collectively studied (practically memorized !) thousands of reference books,museum catalogs,etc.
It's made me appreciate Jewelry,Glass,Pottery,etc much more.I knew the 'biggies' of course-Tiffany,Lalique,etc-but the value of costume jewelry or a Judith Leiber handbag was enlightening.
PS- Apologies for my usual long bloviation,learning to edit.
