About this 0.34ct lab-grown cushion diamond

This 0.34ct lab-grown cushion sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG678542287 or 678542287. Listed at 15 retailers as of November 4, 2026, with a 381% 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.
