About this 1.4ct lab-grown oval diamond

This 1.4ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG606355006 or 606355006. Listed at 16 retailers as of October 29, 2026, with prices from £199 to £1,205, a £1,007 spread on the same certified stone. Taylor and Hart lists it at £1,205. 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.
