About this 2.5ct lab-grown princess diamond

This 2.5ct lab-grown princess sits in the two to three carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG506195903 or 506195903. Listed at 11 retailers as of November 4, 2026, with a 306% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
