This 1.37ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG611391153 or 611391153. Listed at 18 retailers as of October 28, 2026, with prices from £291 to £1,097, a £806 spread on the same certified stone. Reve Diamonds lists it at £1,097. 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.
