About this 0.4ct natural radiant diamond

This 0.4ct natural radiant sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 7 retailers as of October 31, 2026, with a relatively tight 24% spread, which is unusual at this carat range and suggests competitive pricing across the listings. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
