About this 3.73ct lab-grown oval diamond

This 3.73ct 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 LG563201019 or 563201019. Listed at 17 retailers as of October 30, 2026, with prices from £396 to £2,172, a £1,776 spread on the same certified stone. Brilliant Earth lists it at £2,172. 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.
