Frequently Asked Questions
How big does a 3 carat diamond look on the hand?
A 3 carat round diamond measures roughly 9.1mm in diameter — a noticeably large, statement-making center stone. Elongated shapes like oval, pear, or marquise can appear even larger for the same carat weight.
What's the price of this Cushion Halo lab-grown diamond ring across different gold karats?
At The Karat Store, this Cushion Halo lab-grown diamond ring starts at $2,839.2 in 10K gold, $3,203.2 in 14K gold, and $3,640 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 — a practical choice to pair with a 3 carat center stone.
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. 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 for the gold setting, and store the ring separately to prevent scratching.
