About this 3.7ct lab-grown oval diamond

This 3.7ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG547256081 or 547256081. Listed at 15 retailers as of October 27, 2026, with prices from £678 to £3,709, a £3,032 spread on the same certified stone. Brilliant Earth lists it at £3,709. 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.
