About this 1.58ct natural oval diamond

This 1.58ct natural oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6535973538. Listed at 18 retailers as of October 27, 2026, with prices from $7,564 to $14,505, a $6,941 spread on the same certified stone. NZ Jewellers lists it at $14,505. 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.
