the close ups are blurred so it’s hard to see the crystal shapes… the presence of mica indicates it’s a granitic or felsic metamorphic rock… the crystals are mostly likely drusy quartz…but it’s only a guess… I hope you didn’t pay much for it, as a specimen, not worth more than a few bucks… you were scammed with the river pebbles from the RioGrande river in Albuquerque…
pink to purple mica could be lepidolite, but the pictures are too blurred in close up to tell… small crystals associated with lepidolite are almost always quartz… all rock samples sold should state where they came from… down to the country level…that is a rough guide to provenance… if you have a piece of lithium mica with quartz, it should come with a lable, eg: quartz with lepidolite, Custer County, South Dakota…I have non gem quality indicolite tourmaline in albite… dug it up myself on a mine tailings pile… if I sold sliced samples, I would lable them as “indicolite tourmaline in albite, Bob Ingersol Mine, Custer County, South Dakota”…provenance tells you the geology, and the geology tells you what minerals could be present…
Please Please Please DO NOT continue to buy on Etsy without a known reliable source…Depending on where you live, you would have better luck digging up your own specimens…at least you would know where hey came from which limits the possibilities of what they could be.
