Internally flawless natural stones see the widest bid-ask spread of any clarity grade

The gap between what sellers ask and what buyers offer for internally flawless natural stones is wider than for any other clarity grade, reflecting how few genuinely change hands at any one time.

• Internally flawless stones are rare enough that each sale is closer to a negotiated one-off than a quote against an established going rate.
• Sellers holding a genuinely exceptional stone often ask well above where recent comparable sales landed, betting on a buyer who won't negotiate hard for something unique.
• Buyers, in turn, often anchor to VVS pricing and expect only a modest step up, which is where the spread comes from.

If you're shopping at this clarity level, expect the asking price to be a starting point for negotiation rather than a fixed figure. Ask the trade desk for a read on where a specific stone should land.
