About this 1.51ct lab-grown cushion diamond

This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG544271794 or 544271794. Listed at 14 retailers as of October 28, 2026, with prices from $232 to $1,221, a $989 spread on the same certified stone. Reve Diamonds lists it at $1,221. 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.
