About this 0.51ct natural pear diamond

This 0.51ct natural pear sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI 800673410. Listed at 9 retailers as of October 31, 2026, with a relatively tight 23% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
