Frequently Asked Questions
Is a sapphire eternity ring a good anniversary or gift choice?
Yes — sapphire eternity bands are a meaningful step up from a plain band, symbolizing an unbroken circle of stones, and at 9 on the Mohs scale, sapphire is durable enough to wear every day.
How much does this sapphire eternity ring cost in solid gold?
Pricing on this sapphire eternity ring runs from $771.42 (10K gold) to $870.32 (14K gold) to $989 (18K gold) at The Karat Store, with every option solid gold throughout.
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.
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 (10K, 14K, or 18K) 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 will carry a karat hallmark stamp as proof of authenticity.
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. Skip chlorine, bleach, and ultrasonic cleaners, and keep it in its own pouch or compartment to avoid scratches from other jewelry.
