Sorry to bug, but can someone tell me what this stone is? I found it in an old quarry/riverbed and it stood out amongst all the other river rocks. Its heavy, cold, and when I scratched it with an ice pick, traces of steel were left behind w NO gouging. Thankyou for your time
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.
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.
