This 1.3ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2556088072. Listed at 5 retailers as of November 3, 2026, with a relatively tight 15% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
