About this 1.7ct lab-grown heart diamond

This 1.7ct lab-grown heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG478103526 or 478103526. Listed at 3 retailers, with prices from $635 to $755 at 77 Diamonds, a $120 spread on the same certified stone. 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.
