This 1.7ct lab-grown round sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 5222950674. Listed at 4 retailers as of October 31, 2026, with a relatively tight 17% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
