This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG494178637 or 494178637. Listed at 8 retailers as of October 30, 2026, with prices from $518 to $4,121, a $3,603 spread on the same certified stone. Do Amore Diamonds lists it at $4,121. 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.
