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 I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG526291313 or 526291313. Listed at 18 retailers as of November 4, 2026, with prices from $708 to $3,055, a $2,347 spread on the same certified stone. MOH London lists it at $3,055. 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.
