This 1.7ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG845616125 or 845616125. Listed at 20 retailers as of October 27, 2026, with prices from £225 to £1,162, a £937 spread on the same certified stone. With Clarity lists it at £1,162. 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.
