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 2536596645. Listed at 20 retailers as of October 31, 2026, with prices from $21,613 to $36,904, a $15,291 spread on the same certified stone. MOH London lists it at $36,904. 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.
