About this 3.06ct natural round diamond

This 3.06ct natural round sits in the three to five carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2241052248. Listed at 5 retailers as of November 4, 2026, with a relatively tight 12% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
