About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 689598816. Listed at 17 retailers as of October 30, 2026, with prices from $2,007 to $5,370, a $3,364 spread on the same certified stone. NZ Jewellers lists it at $5,370.
