Frequently Asked Questions
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.
What's the price of this Three Stone lab-grown diamond ring across different gold karats?
At The Karat Store, this Three Stone lab-grown diamond ring starts at $2,172.30 in 10K gold, $2,450.80 in 14K gold, and $2,785 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.
Is this ring durable enough for everyday wear?
Yes. Diamond — lab-grown or natural — rates 10 on the Mohs hardness scale, the hardest natural material, making it exceptionally durable for daily wear as an engagement ring.
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.
