About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded D colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566495165. Listed at 9 retailers as of October 30, 2026, with prices from $12,308 to $18,414, a $6,106 spread on the same certified stone. NZ Jewellers lists it at $18,414. 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.
