About this 5.7ct lab-grown marquise diamond

This 5.7ct lab-grown marquise sits in the over five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2507110960. Listed at 3 retailers as of October 31, 2026, with prices from £4,565 to £5,470, a £905 spread on the same certified stone. Kay Jewelers lists it at £5,470. 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.
