How big are the stones in real life?

The set is 1/4 ct tw, so the two marquise stones together total a quarter carat. Each earring is roughly 1/8 ct, which looks like a small, delicate stud.

Are these real diamonds?

They are lab-grown diamonds, which have the same physical and optical properties as mined diamonds but are made in a lab. They are not diamond simulants like cubic zirconia.

Will the sterling silver tarnish?

Yes, sterling silver darkens over time with exposure to air and moisture. Store them dry and clean them with a silver polishing cloth to keep the shine.

Is $279.99 a good price?

Only one new price is listed, $279.99 at Kay Outlet as of November 5, 2026, so there is no recent range to compare. Lab-grown diamond studs in silver commonly sell in the low hundreds, so it sits in a normal band.

What comes in the box?

You get the pair of stud earrings with their backs, typically in KAY gift packaging. Confirm the backing type and packaging on the listing before ordering.

Are they good for a Mother's Day gift?

KAY markets this set for mothers, and the classic solitaire style suits a range of ages. The small size and silver setting make it a modest gift rather than a statement piece.
