About this 14.6ct lab-grown cushion diamond

This 14.6ct lab-grown cushion 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 1236014266. Listed at 10 retailers as of October 30, 2026, with a relatively tight 7% 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.
