About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded N colour (tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6562221436. Listed at 9 retailers as of October 31, 2026, with a relatively tight 20% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
