About this 5.55ct natural round diamond

This 5.55ct natural round sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade and certified by GIA 2566769091. Listed at 2 retailers as of October 31, 2026, with a relatively tight 8% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
