About this 1.72ct lab-grown princess diamond

This 1.72ct lab-grown princess sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG649406094 or 649406094. Listed at 5 retailers as of November 5, 2026, with prices from £144 to £878, a £734 spread on the same certified stone. MOH London lists it at £878. 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.
