"This black gravel Jadeite, an all-risk rough stone, starts at 580,000. Each bid increase must be no less than 5,000. Now, the auction begins," the auctioneer announced loudly.
"600,000."
"620,000..."
"Gentleman number 25 bid 620,000, oh, lady number 57 bid 650,000..."

Typically, the price for all-risk rough stones can range from a few hundred to millions. Those exceptionally large in size with good surface quality can reach tens of millions, though such rough stones are rare.
All-risk rough stones valued under 10,000 are considered low-grade, generally small in volume and with more cracks; those ranging from tens of thousands to hundreds of thousands are medium-grade, displaying a decent surface quality.
