The website admits even Nordstrom isn't sure of the item's purpose.
"A paperweight? A conversation piece? A work of art? It's up to you, but this smooth Los Angeles-area stone -- wrapped in rich, vegetable-tanned American leather secured by sturdy contrast whipstitching -- is sure to draw attention wherever it rests," the website states.
Nordstrom is offering a smaller version of the rock for a more budget-conscious $65.
An earlier version of the listing indicated the stones themselves were "hand-made," but Nordstrom spokeswoman Brie Cross admitted to BuzzFeed News that while the leather pouches are hand-made, "only Mother Earth can take credit for rocks."
The rock listing received some tongue-in-cheek reviews from alleged customers.
"A game-changer -- it's a lady magnet. You'll never be alone if you have this stone in the pocket of your pants," one reviewer wrote.
Despite the jokes at the item's expense, it appears to be popular -- Nordstrom's website listed the medium rock as sold out as of Wednesday.
