Frequently Asked Questions
Why choose a diamond ring over a plain gold band?
Diamond rates 10 on the Mohs hardness scale, the hardest of any gemstone, so this piece holds up well to everyday wear.
What's the price range for this Eternity diamond ring across different gold karats?
At The Karat Store, this Eternity diamond ring starts at $772.2 in 10K gold, $871.2 in 14K gold, and $990 in 18K gold — all solid gold, not plated, with the price difference reflecting gold purity rather than design.
Should I choose 10K, 14K, or 18K gold for this eternity ring?
It comes down to priorities: 18K gold has the deepest color and softest finish, 14K gold is the everyday favorite for its balance of strength and value, and 10K gold is the toughest and most budget-friendly of the three.
Can this eternity 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 take care of a diamond gold ring at home?
Clean it 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.
