About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 6522090375. Listed at 21 retailers as of October 25, 2026, with prices from $4,936 to $11,187, a $6,251 spread on the same certified stone. NZ Jewellers lists it at $11,187. 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.
