About this 13.2ct lab-grown radiant diamond

This 13.2ct lab-grown radiant sits in the over five 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 5221953222. Listed at 6 retailers as of November 1, 2026, with a relatively tight 20% 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.
