About this 4ct lab-grown asscher diamond

This 4ct lab-grown asscher sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG828645999 or 828645999. Listed at 5 retailers as of November 1, 2026, with prices from £405 to £2,954, a £2,548 spread on the same certified stone. Frank Darling lists it at £2,954. 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.
