Frequently Asked Questions
What makes this design different from a plain ring?
The detailed setting gives this piece a distinct look compared to a simple band, while still being practical enough for everyday wear.
How much does this diamond ring cost in solid gold?
Pricing on this diamond ring runs from $1,326 (10K) to $1,496 (14K) to $1,700 (18K) at The Karat Store.
Should I choose 10K, 14K, or 18K gold for this ring?
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.
Is this ring solid gold all the way through, or just gold-plated?
This ring is solid gold throughout, not gold-plated — the karat purity runs all the way through the metal, not just a surface layer. Unlike plated jewelry, it won't flake, discolor, or expose base metal over time, and it carries a karat hallmark stamp as proof of authenticity.
Can this ring be resized?
Yes. Select your ring size from the dropdown before checkout. If you're unsure of your size, we recommend visiting a local jeweler for an accurate measurement.
How do I clean and care for this ring so it lasts?
Clean every few weeks with warm water, a mild soap, and a soft brush, then dry thoroughly. Avoid chlorine, harsh chemicals, and ultrasonic cleaners, and store the ring separately to prevent scratching.
