About this 1.5ct lab-grown round diamond

This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG400945006 or 400945006. Listed at 6 retailers as of November 5, 2026, with prices from $2,887 to $4,603, a $1,716 spread on the same certified stone. NZ Jewellers lists it at $4,603. 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.
