About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559502974. Listed at 23 retailers as of October 30, 2026, with prices from $1,308 to $4,989, a $3,682 spread on the same certified stone. NZ Jewellers lists it at $4,989. 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.
