About this 1.73ct lab-grown cushion diamond

This 1.73ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG414069541 or 414069541. Listed at 11 retailers as of October 27, 2026, with prices from $559 to $3,101, a $2,542 spread on the same certified stone. Diamond Exchange Canada lists it at $3,101. 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.
