This 3.01ct lab-grown round sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG546221589 or 546221589. Listed at 12 retailers as of October 29, 2026, with prices from $688 to $3,150, a $2,462 spread on the same certified stone. MOH London lists it at $3,150. 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.
