About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by GIA 6405144471. Listed at 19 retailers as of October 29, 2026, with prices from $8,533 to $15,133, a $6,600 spread on the same certified stone. MOH London lists it at $15,133. 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.
