About this 1.61ct lab-grown oval diamond

This 1.61ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG537250352 or 537250352. Listed at 13 retailers as of October 29, 2026, with prices from £151 to £829, a £679 spread on the same certified stone. MOH London lists it at £829. 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.
