This 1.4ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG833671681 or 833671681. Listed at 17 retailers as of November 4, 2026, with prices from $259 to $1,453, a $1,194 spread on the same certified stone. Reve Diamonds lists it at $1,453. 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.
