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 VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 497180144. Listed at 17 retailers as of October 31, 2026, with prices from $2,950 to $7,159, a $4,209 spread on the same certified stone. NZ Jewellers lists it at $7,159. 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.
