Frequently Asked Questions
Is this a good choice for an engagement ring?
Yes. A 3 carat lab-grown diamond gives you significant size and brilliance at a fraction of the cost of a natural diamond of the same weight, making it a popular choice for couples who want a statement stone without the natural-diamond price tag.
How much does this 3 carat lab-grown diamond ring cost in solid gold?
Pricing on this lab-grown diamond ring runs from $3,178.50 (10K) to $3,586 (14K) to $4,075 (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.
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.
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.
