About this 1.03ct lab-grown asscher diamond

This 1.03ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG450012180 or 450012180. Listed at 11 retailers as of October 29, 2026, with prices from $213 to $1,225, a $1,012 spread on the same certified stone. MOH London lists it at $1,225. 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.
