About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 839656880. Listed at 9 retailers as of October 29, 2026, with prices from £244 to £934, a £690 spread on the same certified stone. NZ Jewellers lists it at £934.
