Frequently Asked Questions
Is this ruby half eternity ring worth buying compared to a plain wedding band?
Yes. Eternity rings symbolize everlasting love and are a popular anniversary, push present, or stacking ring choice. Ruby rates 9 on the Mohs hardness scale, so it holds its brilliance over years of daily wear.
What's the price range for this ruby half eternity ring across different gold karats?
At The Karat Store, this ruby half eternity ring starts at $1,618.5 in 10K gold, $1,826 in 14K gold, and $2,075 in 18K gold — all solid gold, not plated.
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.
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 (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.
What's the best way to keep this ruby ring looking new for years?
Soak briefly in warm water with a drop of mild dish soap, gently brush with a soft-bristled brush, rinse, and pat dry. Avoid chlorine, harsh chemicals, and ultrasonic cleaners, and store the ring separately to prevent scratching.
