About this 1.53ct lab-grown oval diamond

This 1.53ct 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 LG852654707 or 852654707. Listed at 5 retailers as of October 29, 2026, with prices from £246 to £625, a £379 spread on the same certified stone. Taylor and Hart lists it at £625. 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.
