This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG846691579 or 846691579. Listed at 2 retailers as of October 30, 2026, with prices from $300 to $627, a $327 spread on the same certified stone. 77 Diamonds lists it at $627. 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.
