Hey, Trying to help the local who has an amazing collection for sale. He has about 6 slabs of this. I was at a loss for ID. Unknown location. Some slabs have lots of dendrites. Thanks

Thanks I received similar material in a box from stardiamond. I have seen similar things on line called Apple Prase and another name I can't remember.

Lemon Chrysoprase maybe moonrisecrystals.com/tumbled-stones/lemon-citron-chrysoprase-nickeloan-magnesite/"Mineral Family: Despite its name, Citron Chrysoprase is not a type of Chrysoprase! It is actually a rare form of Magnesite, a Carbonate mineral. Carbonates are an important part of the Earth’s crust and are found in sedimentary, metamorphic, and igneous rocks. Carbonates are minerals which contain the carbonate group CO3 as their basic structural unit. They form in a trigonal system with one carbon atom centrally located between 3 oxygen atoms. While there are over 70 types of Carbonate minerals, the most common are Dolomite, Siderite, and Calcite. Magnesite is a relatively rare stone, which usually forms in massive slabs, although occasional fine crystals have been found. It is closely related to Aragonite, Calcite, Malachite, and Rhodochrosite."

Green common opal is also a reasonable guess, test the hardness.
