Cashmere Yarn

I have two 400 yd hanks of 100% cashmere yarn for sale. It is 2-ply fingering weight and the most beautiful shade of lavender. My picture doesn’t do it justice. I wound one of the hanks into a ball and swatched with it, but I didn’t cut the yarn and rewound it. I’m asking $25 plus shipping. I would consider a trade for cashmere in a heavier weight.

Could you tell me the brand name? and how many sts to the inch and size needle you would use with this?

I bought it on eBay and believe it is hand-spun. It calls for size US1-3 needles and gets 6-8 sts = 1 inch.
