About this 3.05ct lab-grown round diamond

This 3.05ct 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 LG605341394 or 605341394. Listed at 12 retailers as of November 4, 2026, with prices from $444 to $1,989, a $1,545 spread on the same certified stone. MOH London lists it at $1,989. 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.
