This 0.55ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG764675323 or 764675323. Listed at 10 retailers as of November 1, 2026, with prices from £226 to £1,662, a £1,436 spread on the same certified stone. Do Amore Diamonds lists it at £1,662. 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.
