This 1.73ct lab-grown heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG838645253 or 838645253. Listed at 6 retailers as of October 26, 2026, with prices from $524 to $1,257, a $733 spread on the same certified stone. MOH London lists it at $1,257. 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.
