Frequently Asked Questions
Is a signet diamond ring a good everyday piece?
Yes. Diamond rates 10 on the Mohs hardness scale, and set in solid gold, this signet ring holds up well to daily wear.
How much does this signet diamond ring cost in solid gold?
Pricing on this signet diamond ring runs from $1,115.40 (10K) to $1,258.40 (14K) to $1,430 (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.
