Is a bezel setting good for a pear-cut diamond?

Yes. The pear's pointed tip is its most fragile spot, and a bezel wraps the whole girdle, so the point is protected from knocks. The trade-off is that the metal covers the stone's rim, which can reduce edge sparkle compared with prongs.

What does IGI certification mean here?

IGI is an independent gemological lab that grades the diamond's cut, color, clarity and carat weight and issues a report. Ask for the report number so you can verify the stone matches the certificate.

Will sterling silver hold up for daily wear?

Sterling silver is durable enough for regular wear but tarnishes over time and scratches more easily than white gold or platinum. It also wears thinner at the setting over years, so it may need re-tipping or replating.

Can this ring be resized?

A plain silver band can usually be resized by a jeweler, but a full bezel setting limits how much the shank can move. Have a jeweler assess it before resizing, and avoid repeated resizing.

How does a lab grown diamond compare with a mined one?

They are chemically and optically identical; only the origin differs. Lab grown stones carry the same hardness and sparkle and come with lab grading, which is why they cost less than mined equivalents.
