About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558492101. Listed at 23 retailers as of October 30, 2026, with prices from $11,285 to $25,000, a $13,715 spread on the same certified stone. NZ Jewellers lists it at $25,000. 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.
