About this 1.59ct lab-grown oval diamond

This 1.59ct lab-grown oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG850602559 or 850602559. Listed at 7 retailers as of October 30, 2026, with prices from £170 to £904, a £734 spread on the same certified stone. Reve Diamonds lists it at £904. 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.
