About this 3.11ct lab-grown heart diamond

This 3.11ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1505425847. Listed at 19 retailers as of November 4, 2026, with a relatively tight 19% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
