About this 0.56ct natural marquise diamond

This 0.56ct natural marquise sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5221666686. Listed at 4 retailers as of November 4, 2026, with prices from £457 to £969, a £512 spread on the same certified stone. MOH London lists it at £969. 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.
