About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded K colour (faint-tinted) and VVS2 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6565381807. Listed at 3 retailers as of November 1, 2026, with prices from £437 to £527, a £90 spread on the same certified stone. 77 Diamonds lists it at £527. 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.
