About this 1.4ct lab-grown cushion diamond

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 very-good cut grade and certified by IGI LG629441943 or 629441943. Listed at 11 retailers as of November 4, 2026, with prices from $356 to $2,050, a $1,694 spread on the same certified stone. Do Amore Diamonds lists it at $2,050. 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.
