About this 2.5ct natural oval diamond

This 2.5ct natural oval sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2517690765. Listed at 21 retailers as of October 29, 2026, with prices from $28,874 to $50,607, a $21,733 spread on the same certified stone. MOH London lists it at $50,607. 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.
