About this 2.5ct natural oval diamond

This 2.5ct natural oval sits in the two to three carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7506811321. Listed at 14 retailers as of November 2, 2026, with prices from $25,811 to $42,120, a $16,308 spread on the same certified stone. MOH London lists it at $42,120. 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.
