About this 0.4ct natural oval diamond

This 0.4ct natural oval sits in the sub-half-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6425904725. Listed at 20 retailers as of October 30, 2026, with prices from £293 to £1,312, a £1,019 spread on the same certified stone. NZ Jewellers lists it at £1,312. 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.
