Frequently Asked Questions
Are these diamond studs a good choice for daily wear or special occasions?
Yes. Diamond rates 10 on the Mohs hardness scale, and combined with solid gold posts and settings, these studs hold up well to daily wear.
What's the price range for these diamond studs across different gold karats?
At The Karat Store, these diamond studs start at $1,216.8 in 10K gold, $1,372.8 in 14K gold, and $1,560 in 18K gold — all solid gold, not plated.
Should I choose 10K, 14K, or 18K gold for these earrings?
18K gold gives the deepest color, 14K gold is the everyday favorite for its balance of strength and value, and 10K gold is the toughest and most budget-friendly.
Are these earrings safe for sensitive ears?
Yes. Unlike gold-plated jewelry, solid gold does not flake or expose base metal, making it naturally hypoallergenic and a safe choice for sensitive or pierced ears.
What's the best way to keep these diamond earrings looking new?
Wipe gently with a soft, lint-free cloth after wearing, and occasionally clean with warm water and a drop of mild soap. Avoid perfume, lotion, and chlorine contact, and store separately to prevent scratching.
