About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 7511609163. Listed at 20 retailers as of October 30, 2026, with prices from $2,271 to $7,161, a $4,890 spread on the same certified stone. NZ Jewellers lists it at $7,161. 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.
