This 0.73ct lab-grown princess sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG834603336 or 834603336. Listed at 3 retailers as of November 1, 2026, with prices from £156 to £936, a £780 spread on the same certified stone. Do Amore Diamonds lists it at £936. 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.
