Alameda creek.
Well, California does have jade, but I don't know that area. You might want to reach out to your local Gem and Mineral society for help.
Big Sur Jade
The Big Sur coast is world famous for its rugged beauty and sweeping vistas, and for its beautiful green nephrite jade that washes up on the beaches.www.rockhoundtimes.com
Is it very heavy and cold to the touch?...oops. I re-read what you wrote - no scratches with a knife, heavy and cold...sounds very possible.
I've been busy buying jades, both nephrite and jadeite. They are not the finest quality...I've been living up to my magpie collection tendencies and limited budget. My collection is modest and not the best of PS by a long shot. However, I am learning from my mistakes, so that is something. Since I have a little of everything now, I will move forward more deliberately. I have one more jadeite bangle on the way -it is baby blue with a fine texture to replace one I loved, but was too small for comfort.
These are my grade A jadeites to date. The bracelet with the yellow patch may have a spot treatment where it glows under UV. It has a NQTC cert,so not sure if this could be a natural occurrence (?).
Thanks for the information, @AJadecent Angle. I am so sorry you opened that in an embarrassing situation with family! The green bangle is deteriorating over time, getting a little more spiderwebbed, although still green. Looking back I just should have known.Wow! I'm definitely late but I've gotten pieces from gojade and definitely say the red/brown/yellow pieces from her (and generally coming from other sellers) are heat treated since a element giving the jade a yellow/brown look become red due to it being dehydrated to give it the burnt red look. So in China, they still consider heat treated jade grade A since technically the jade structure isn't physically altered, just chemically altered by intense heat. I personally believe NQTC is legit as I know another ebay seller who has certs coming from them as well dating from 2018-2019.
Oh and I scanned the barcode for the treated green jade bangle you posted earlier and it's definitely a fake (cause it led me to the aforementioned adult pleasure advertisements)
quite embarrassing to open up in front of relatives.

No worries, we all gotta make mistakes to learn and take it as experience (even if our bank accounts will be sobbing in the process )
I personally think you can learn alot more of jade in Chinese sites that specializes in jade, I even have a bookmarked jade forum site that specifically posts pictures of B+C jades that is definitely a lifesaver so I may as well post it here!

I appreciate your time. Alameda Creek is located in Fremont Ca. which is between San Francisco and San Jose. I tried scratching w an ice pick but it only created a spine-chilling squeak and no grooves.
The bangle came from Ultimate Jadeite. I was attracted to the high contrast stormy and icy look. I can easily get it on with lotion and notice going smaller than my white and green flower bangle is nice. More comfortable to wear and it does not slide up when I sleep.
Lesson learned that a little smaller feels better. I wonder how much smaller is good until I am at "too small", Hmmmm.
Thank you very much! I have kept it on every day since it arrived. It is so comfortable.
So beautiful. I am barely beginning to learn about jade. I am especially loving 'moss in snow' jade, which I think this is.
