About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7562378666. Listed at 4 retailers as of November 1, 2026, with prices from £418 to £593, a £175 spread on the same certified stone. Steven Stone lists it at £593. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
