Is 1/2 ct total weight the same as a half-carat center stone?

No. The 1/2 ct figure covers all the diamonds together, so the center stone is smaller than a half-carat solitaire. The halo stones make up the rest of the weight.

Is 10K white gold good for earrings?

10K is durable and costs less than 14K, but it has a lower gold content and its white rhodium finish can wear off over time. Replating restores the bright white look.

Are these earrings a good price at $749.99?

That is the only new price listed, at Kay Jewelers as of November 7, 2026, so there is no competing store price to beat it. Compare against other 1/2 ct halo studs in 10K white gold before deciding.

What backs the diamonds?

Kay sells these as diamond stud earrings in a halo setting. Ask about the diamond grading and the warranty terms at purchase, since the listing does not spell them out.

Will the halo stones fall out?

Small halo stones are held by tiny prongs and can loosen with daily wear. Have the prongs checked once or twice a year and avoid catching them on clothing or hair.
