Lab Grown Diamonds
Ethically Crafted. Certified. Brilliant Value.
Lab grown diamonds represent the modern evolution of fine jewelryβwhere timeless elegance meets responsible innovation. These diamonds are real diamonds, offering the same brilliance, durability, and beauty as mined diamonds, while aligning with todayβs values of transparency, sustainability, and ethical sourcing.
At Stienhardt, we make it effortless to buy lab-created diamonds with confidence. Whether you are selecting loose diamonds or designing grown diamond engagement rings, our collection delivers certified diamond quality, exceptional value, and complete peace of mindβwithout compromise.
What Are Lab Grown Diamonds?
Lab grown diamonds are genuine diamonds created in advanced laboratory environments that replicate the natural diamond-growing process. They share the same chemical composition, crystal structure, optical performance, and hardnessβhaving the same properties as natural diamonds.
The only difference lies in their originβnot their beauty, strength, or authenticity.
Often referred to as lab-created diamonds, engineered diamonds, or created diamonds, these stones are recognized by leading gemological institutions as real diamonds.
How Lab Grown Diamonds Are Created
Modern laboratories rely on two proven methods to grow diamonds with precision and consistency:
High Pressure High Temperature (HPHT)
This method recreates the extreme heat and pressure found deep within the Earth. Carbon crystallizes into a diamond structure identical to that of naturally mined stones.
Chemical Vapor Deposition (CVD)
CVD uses carbon-rich gas to grow diamond crystals layer by layer, allowing exceptional control over clarity, structure, and overall quality.
Both processes produce diamonds with identical hardness, sparkle, and longevityβmaking them ideal for lab grown diamond jewelry designed to last a lifetime.
Why Choose Lab Grown Diamonds?
Luxury buyers today are redefining what value means. Lab-created diamonds appeal to those who seek beauty, intelligence, and responsibility in equal measure.
Key Advantages

Ethically sourced diamonds with no conflict mining
-
Eco-friendly production with significantly lower environmental impact
-

These benefits make lab grown diamond engagement rings, man-made diamond jewelry, and created diamond rings a preferred choice for couples and collectors alike.

Synthetic diamonds deliver exceptional visual performance and durability. With a hardness of 10 on the Mohs scale, they are highly resistant to scratching and perfectly suited for daily wear.
