About this 0.51ct lab-grown cushion diamond

This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG785606163 or 785606163. Listed at 12 retailers as of November 1, 2026, with a 484% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
