About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1525843537. Listed at 28 retailers as of November 5, 2026, with prices from $649 to $2,754, a $2,105 spread on the same certified stone. NZ Jewellers lists it at $2,754. 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.
