About this 2.05ct lab-grown cushion diamond

This 2.05ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG528213428 or 528213428. Listed at 5 retailers as of October 29, 2026, with prices from $710 to $1,696, a $986 spread on the same certified stone. MOH London lists it at $1,696. 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.
