About this 1.45ct lab-grown radiant diamond

This 1.45ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2507851204. Listed at 25 retailers as of October 30, 2026, with a 227% 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.
