About this 2.05ct lab-grown round diamond

This 2.05ct lab-grown round sits in the two to three carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG445037793 or 445037793. Listed at 11 retailers as of November 3, 2026, with prices from $1,726 to $12,109, a $10,384 spread on the same certified stone. MOH London lists it at $12,109. 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.
