18K Solid Gold Solitaire Lab Grown Diamond 3ct Engagement Ring An essence of beauty. This ravishing ring features a singleton, magnificent 3.00 ct lab-grown diamond famed for brilliancy and purity. What catches the eye from a 3.00 ct lab-grown diamond is its VVS-VS clarity with an E-F color. In itself, that sparkle is the perfect symbol of time-transcending love.
The engagement ring is made from 18K Solid Gold and can be bought in one of three beautiful finishes, either in rose gold, yellow gold, or white gold. For those who desire even more elite sophistication, 18K Solid Gold finishes are also available, though by special request. The band is set in with a width and thickness of 1.50 mm to be both beautiful and comfortable to wear every day, effortlessly.
Lab-grown diamonds are produced with the latest technology and do not support the environmental or social problems associated with the mining of traditional diamond miners. This ring makes not only a lovely statement of love but supports a sustainable practice.
The Karat Store focuses on ethical origins and exquisite craftsmanship in jewelry. Quality, beauty, and sustainability come before everything else. If that sounds like what you are after, the 18K Solid Gold Solitaire Lab Grown Diamond 3ct Engagement Ring is the choice.

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.
How much does this 3 carat lab-grown diamond ring cost in solid gold?
Pricing on this Solitaire lab-grown diamond ring runs from $3,210 (10K) to $3,210 (14K) to $3,210 (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.
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.
