I really like your bangle combos, my favorite is that bead bracelet with specks of green.

Thanks so much Jadies! I think I finally realized I had the perfect bumper in this silver bangle
Hey piosavsfan! The beaded bracelet is Dushan jade from reikocrystalbeads on eBay ☺️
CR, how lovely!! I love that shade of green!
Thanks so much Silverstar! It was such a nice day yesterday I had to catch a picture. Still wearing them today
Thanks CR, the silver bracelet is perfect with your bangle and beads, I love the cool color combination of silver and green. No wonder you are still wearing them!
I like the idea of having a pop of nephrite bead among the jadeite ones. Though, are you not afraid that the silver bead will leave black marks on the neighboring jadeite beads? That’s the one reason I switch all pendant bails to string because both sterling and 14kt clasps leave black marks on the drill holes!
Thanks so much JB! Sorry I missed this, we are having bad weather here ugh! I hope everyone is safe and stays that way. Take care Jadies
Udalrike, your chubby nephrite princess is pretty. May you share where/seller you got it from?
Hi Jadies, I have a quick question about a certificate for a bangle from the PNJ lab in Vietnam. Does anyone know if they can be trusted? The certificate does not say "Grade A" anywhere, just "Natural jadeite" and the S.G is a questionable 3.28 g/cu.cm.
Does anyone know if certificates from this lab usually indicate "Grade A" if it is? The notes say "Natural color" but no notes that there are no polymers present. Let me know if you have used this lab before and what a grade A certificate from them usually states.

Wishing everyone a great weekend!

Hi JB,
If you go to etsy app/web, search for SHOP (not seller name) wandajewelry2013, search for “bangle” and sort result from high to low prices, you’ll see their $2000 bangles have the same reading/info i.e. natural color, uv inert, spectrum of jadeite etc as seen for some bangles priced at $350 that are obviously treated. I mention this shop because the bangles that come with certificates are all from PNJ lab in Ho Chi Minh City in Vietnam. This lab cannot be trusted as some bangles are grade A but lots are grade B/C and still have certificates. Some sellers will tell you this lab from Vietnam will not issue certificates unless the jade is grade A-do not believe that statement. I’m Vietnamese myself and visited that PNJ stores a few times and spotted plenty treated jade along with the legits. Cut long story short, you have to rely on your ability to spot untreated jade.
On another note, some bleached jade will still have specific gravity around 3.3. Also, some bleached jade will not react to UV test either; this info is confirmed by research papers. Take a look at the paper here https://www.researchgate.net/profil...egnated-jadeite.pdf?origin=publication_detail
So if anyone here has a piece of jade that looks like million buck and “passed” the uv light test and specific gravity test, you still should do FTIR test. Clearly the belief that bleached jade is “lighter” than untreated jade cannot be relied on. Also some bleached AND dyed jade are done so well that you cannot spot that “spider web” with 10x magnifying glass either. Mason kay does email result option (no report) for $70 as opposed to report for $110.
Hi Vicky, Thanks for the detailed explanation.
This is what I suspected. I only trust IR spectroscopy for a definitive answer, but did not know about this lab and it looked sketchy in the properties they list and the way they describe the jade. This confirms my suspicions.
I was not sure about the properties of bleached wax though as I thought "bleached" should show up in the fluorescence filling in stone lines but I will look into the paper you sent. This is great help. Thanks for sharing all the info with us here!

I read a paper published by GIA that found bleached only and the bleached+impregnated jade would react to UV but that paper was done in 1992. Posting that 1992 GIA paper here in case some want to read it: https://www.gia.edu/doc/Identification-of-Bleached-and-Polymer-Impregnated-Jadeite.pdf
Apparently, with advanced technology, the filling materials in newer (treated) jade don’t react to UV light-I guess the conniving jade business learned that many people walk around jade markets with a UV light to test on spot and so they “evolve”.

Hi Vicky,
I didn’t know that silver and gold will leave black marks on the drill holes. Thanks for your information! At the same time, I’m more of the “enjoy the NOW” type so I think even with that knowledge, I will still keep the Pandora bead on the bracelet. It just brings me so much joy looking at it.
I hope all the Jadies are enjoying there weekend. Quite a bit of bad weather going out there stay safe everyone! Wearing bead stack today Still yucky out and keeping my fingers crossed we don’t lose power again. I’m so over this bad weather, but nephrite does bring a smile to my face
