About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG844628226 or 844628226. Listed at 10 retailers as of October 25, 2026, with prices from £174 to £747, a £573 spread on the same certified stone. Reve Diamonds lists it at £747. 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.
