About this 2.56ct lab-grown heart diamond

This 2.56ct lab-grown heart sits in the two to three carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6491749798. Listed at 18 retailers as of October 29, 2026, with a 330% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Lab-grown prices in the 2ct and up range have fallen 40 to 60% over the last 18 months. Use the cross-retailer spread above to find the lowest current listing.
