About this 1.5ct lab-grown oval diamond

This 1.5ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG494186030 or 494186030. Listed at 23 retailers as of October 30, 2026, with prices from €238 to €1,038, a €800 spread on the same certified stone. Brilliant Earth lists it at €1,038. 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.
