This piece was a gift so I don't know where it came from. Any ideas ??

My first guess would be Washington the second Jade Cove. That mix really looks like Washington nephrite with a bit of chlorite and chrome diopside.Pretty classic.

After my Google image search I'm thinking its Eel river nephrite jade....

Eel river jade can look like that but it has always seemed to be r4ather stingy in the amounts provided.

Hello, this is my first post. My wife and I have become interested in local Puget Sound cobble collecting. I have many questions on rock identifications, which I'm sure I will bore this illustrious group with newbie questions. Your Jade does bear similarities to some of the pieces we've found, so I will be interested to see the different opinions. I do have a basic question re rocks on the salt water beach. Washington Nephrite is expected to have a rind, and most of what we find has a grey rind, however, some of the rocks we find on the beach have no rind and we think they are nephrite, but, flip a coin, they could also be Jasper. So, my question is do Washington Jade cobbles always have a rind, or can some be rindless? I'm trying to attach a photo, as practice, hopefully it will be easy peasy and I'll have lots of slab pics to share and ask about.
Regards,
R.
Petrified wood, this piece is about 20" long and much different than the usual form we find. The pic probably won't show and I'll need to figure it out a bit. But here goes anyway.

The rind on our jade is formed by long immersion in very wet environments. In addition the jade has countless impact marks from the nasty pounding it gets from other cobbles and boulders in the rivers and especially in the ocean. I have seen thousands of pieces of surf chert that people tend to identify as jade as it is rindless and green. I found a couple of hundred surf jades this week alone and all had rinds. I have found two thumb sized pieces of rindless translucent green surf jade in 40 years and I find close to a thousand pieces a year. The short answer possible but not probable. Today we collected a creek where the jade was hardly tumbled and had no rind. It was obviously recently broken out of the host rock. It was easy to identify the color and more importantly some , many, were extremely chatoyant and compact -good cutters but again no green. Great question and good luck collecting. Did you know there is in situ jade outside Ellensburg?

Good morning,
I've wanted to return and participate in this illustrious forum, and towards that end, thought I'd post a photo of what appears, based on your explanation to another poster, is Saussuritized Feldspar - Diabase. I recently acquired a Loretone 14" saw, so I am looking forward to sharing a pics of rocks and cobbles we find on the beach and elsewhere. [ You are not allowed to view attachments ]
