Southern California's Best
Lab-Created Diamond Engagement Rings
Lab-created diamond rings are surging in popularity across Newport Beach, Irvine, and throughout Southern California, and for good reason. Lab-grown diamonds are real diamonds, arriving with authentic diamond certifications and sharing the same physical and chemical properties as traditionally mined stones. They're graded on the same 4 C's, cut, color, clarity, and carat. The only differences: they're not mined from the Earth, and they often cost 50%+ less.
Nathan Alan is Newport Beach's go-to jeweler for lab-grown diamonds. Every ring, wedding band, and fine jewelry piece in our collection can be custom-made with a certified lab-created diamond.

The Science Behind the Stone
Lab-Grown Diamonds
Are Real Diamonds
The term "lab-grown" refers to origin, not authenticity. Lab-grown diamonds are composed of pure carbon arranged in the same crystal lattice structure as mined diamonds. They share the same chemical composition (100% carbon), the same hardness (10 on the Mohs scale), the same refractive index, and the same optical brilliance. They are not simulants. They are not cubic zirconia. They are diamonds.
Every lab-grown diamond we sell is independently certified by IGI (International Gemological Institute) or GIA (Gemological Institute of America) and graded using the same 4Cs as any mined stone: cut, color, clarity, and carat. The only meaningful difference between a lab diamond and a mined diamond is where it formed, and what it costs.
Lab diamonds typically cost 40–50%+ less than a mined diamond of the same grade. That means more stone for your budget, a higher-quality cut, or simply a purchase you feel exceptional about making.
At Nathan Alan, our exceptional earth-mined diamonds and exquisite lab-grown diamonds are both at your fingertips. We source industry-certified lab diamonds to create engagement rings of any style and size. As you browse our fine jewelry collection, consider the benefits of lab-grown diamond rings and more.

The Process
How Lab-Grown Diamonds Are Made
CVD vs. HPHT
Lab-grown diamonds are created using one of two scientific processes, both of which replicate the conditions under which natural diamonds form over millions of years. The result is a diamond that is, in every measurable way, the same as what comes from the Earth.
Nathan Alan exclusively sources CVD diamonds. We hold every stone to a high personal standard, so you can trust the diamond in your ring meets our own bar for quality, not just the industry minimum.
CVD
Chemical Vapor Deposition
A diamond seed crystal is placed inside a sealed chamber and exposed to a carbon-rich gas mixture, typically methane, at extremely high temperatures. The carbon atoms separate from the gas and layer onto the seed crystal, atom by atom, building up a pure diamond over the course of weeks. CVD produces stones of exceptional purity and is the predominant method used for high-quality gem-grade lab diamonds today.
HPHT
High Pressure High Temperature
HPHT replicates the conditions found deep within the Earth's mantle, temperatures exceeding 1,400°C and pressures above 1.5 million pounds per square inch. A diamond seed is placed inside a growth chamber with a carbon source, and under these conditions, the carbon melts and crystallizes around the seed, forming a diamond. HPHT was the first method used to successfully create gem-quality diamonds and continues to produce exceptional stones in a wide range of shapes and sizes.
