Frequently Asked Questions
Is a solitaire diamond ring a good everyday piece?
Yes. Diamond rates 10 on the Mohs hardness scale, and set in solid gold, this solitaire ring holds up well to daily wear.
What's the price range for this solitaire diamond ring across different gold karats?
At The Karat Store, this solitaire diamond ring starts at $1,247.22 in 10K gold, $1,407.12 in 14K gold, and $1,599 in 18K gold — all solid gold, not plated.
Should I choose 10K, 14K, or 18K gold for this ring?
18K gold (75% pure) has the richest color and softest feel. 14K gold (58.3% pure) is the most popular balance of durability and value. 10K gold (41.7% pure) is the most affordable and most scratch-resistant.
How can I tell this is real solid gold and not 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.
