The solitaire is the ring the word "engagement" was practically invented for: a single, breathtaking diamond raised to catch the light. Pair that classic silhouette with a lab grown diamond and you get the best of both worlds—an unmistakably timeless design created through modern, sustainable technology. At Rêve Diamonds, our lab grown solitaire engagement rings deliver the same fire and brilliance as mined stones, often at a fraction of the cost.
A lab grown diamond solitaire ring gives you a chemically identical, real diamond in the most enduring setting there is—usually for 30–50% less than a comparable natural stone. Focus on cut first for maximum sparkle, choose a color and clarity that look eye-clean, and select a metal and setting that suit your lifestyle.
Why the Solitaire Is Endlessly Timeless
Trends in engagement ring design come and go, but the solitaire never dates. Because a single center stone carries the whole design, there is nothing to look old-fashioned a decade from now. It also flatters every hand and pairs effortlessly with almost any wedding band you choose later—from a plain metal band to a slim eternity ring.
Why Choose a Lab Grown Diamond
Lab grown diamonds are real diamonds. They share the same carbon crystal structure, the same 10 on the Mohs hardness scale, and the same sparkle as mined diamonds—the only difference is origin. Grown in a controlled environment over a matter of weeks, they avoid the environmental disruption and supply-chain uncertainty of mining. You can read the full science in our diamond education guide, and compare the two options side by side in our natural vs lab grown price comparison.
Choosing Your Solitaire: The 4Cs
Every diamond, grown or mined, is graded on the same four characteristics. For a solitaire, where the stone stands alone, these matter more than ever:
- Cut: The single biggest driver of sparkle. Prioritize an Excellent or Ideal cut before anything else.
- Color: Graded D (colorless) to Z. For white metals, D–F look icy; in yellow or rose gold, G–I appear beautifully white for less.
- Clarity: VS1–VS2 stones are typically eye-clean, meaning no inclusions are visible without magnification.
- Carat: Because lab grown diamonds cost less per carat, your budget often stretches to a larger, more impressive center stone.
Every Rêve Diamonds lab grown stone is independently certified by GIA or IGI, so the grades you pay for are the grades you get.
Settings and Metals
A four- or six-prong setting lifts the diamond toward the light for maximum brilliance, while a bezel setting wraps the girdle in metal for a sleek, secure, modern look. Platinum offers a naturally white, hypoallergenic finish; 18k white, yellow, or rose gold lets you personalize the tone. If you love a little extra sparkle, a hidden halo or a diamond-set band bridges neatly to a matching eternity ring.
Lab Grown Solitaire Prices in the US
As a rough guide, a well-cut 1-carat lab grown solitaire typically ranges from about $900 to $1,800 depending on color, clarity, and setting, while a 2-carat stone often lands between $2,200 and $4,500. A comparable natural diamond can cost two to three times as much—which is why so many US buyers choose lab grown to size up or save. Explore current options on our lab grown diamonds collection.
Frequently Asked Questions
Are lab grown diamonds real diamonds?
Yes. They are made of the same material—pure crystallized carbon—and share the identical physical, chemical, and optical properties of mined diamonds. Gemologically, they are diamonds in every sense.
Will a lab grown solitaire last a lifetime?
Absolutely. Ranking 10 on the Mohs scale, lab grown diamonds are just as hard and durable as natural ones, making them ideal for a ring worn every day.
Do lab grown diamonds hold sentimental value?
The meaning of a ring comes from what it represents, not from how the stone formed. A lab grown solitaire carries exactly the same promise—with a lighter footprint and often a larger diamond.
