This 3.56ct lab-grown round sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG605341409 or 605341409. Listed at 12 retailers as of October 29, 2026, with prices from $643 to $3,296, a $2,653 spread on the same certified stone. MOH London lists it at $3,296. 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.
