Frequently Asked Questions
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 much does this 3 carat lab-grown diamond ring cost in solid gold?
Pricing on this Round lab-grown diamond ring runs from $2,117.7 (10K) to $2,389.2 (14K) to $2,715 (18K) at The Karat Store.
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.
Is a lab-grown diamond as good as a natural diamond?
Yes — lab-grown diamonds are chemically, physically, and optically identical to natural diamonds, both rating 10 on the Mohs hardness scale. The difference is origin, not quality: lab-grown diamonds are created in a controlled environment rather than mined, which is why a 3 carat lab-grown stone costs significantly less than a natural one of the same size and quality.
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.
