About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1236660078. Listed at 16 retailers as of October 30, 2026, with prices from $16,175 to $28,344, a $12,169 spread on the same certified stone. NZ Jewellers lists it at $28,344. 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.
