Rare 1970s Vintage Diamond Sweater, Small

Rare 1970s Vintage Diamond Sweater, Small This sweater is SO beautiful. I purchased it in the 90s as 1970s vintage. The tags are missing, but feels like a very high quality cashmere or cashmere wool blend similar to ballantine. The pattern is slightly raised and on the front only. There are a few small budding holes which are pointed out in the collage photo. No rip, discoloration or stretching. It has been dry cleaned recently.
