About this 1.55ct lab-grown round diamond

This 1.55ct lab-grown 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 IGI LG407936127 or 407936127. Listed at 3 retailers as of November 4, 2026, with prices from $453 to $1,055, a $602 spread on the same certified stone. MOH London lists it at $1,055. 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.
