For jewelry purposes, SI2 clarity is sufficient to allow for brilliance and dispersion. In most cases, close examination with the naked eye will not reveal any flaws. For engagement purposes, many buyers prefer stones with higher clarity grades. Selecting SI1 or SI2 rather than a VS clarity grade can enable a buyer to own a larger and/or better color diamond for the money; without a substantial drop off in beauty.

*For engagement purposes, I recommend VS2-SI1-SI2 clarity
