This 2.78ct lab-grown round sits in the two to three carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG607309813 or 607309813. Listed at 12 retailers as of October 27, 2026, with prices from $437 to $1,895, a $1,458 spread on the same certified stone. MOH London lists it at $1,895. 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.
