Why Choose Lab-Grown Opal Over Natural Opal?

Lab-grown opal represents the perfect marriage of nature’s beauty and human ingenuity. It captures the mesmerizing fire of the world’s rarest opals while delivering significant advantages in durability, ethics, and vibrancy. Here’s why choosing a lab-grown opal for your jewelry is a brilliant decision.


Engineered for Everyday Life

The most significant advantage of lab-grown opal is its superior strength and stability. Natural opal is famously delicate, containing a high water content that makes it prone to cracking and "crazing" from impacts or temperature changes. This fragility is why it's often avoided for daily-wear pieces like engagement rings.

Our lab-grown opals solve this problem. By creating the opal in a controlled environment, a gem is produced that is far more resilient and durable. You can wear your opal jewelry with confidence every day, without the constant worry of damaging your precious stone.

Unmatched Vibrancy & Fire

While natural opals can be stunning, their quality and play-of-color can be inconsistent. The beauty of a lab-grown opal is the remarkable consistency and vibrancy of its fire. The process cultivates a flawless, intricate structure that results in a breathtaking and uniform play-of-color, a feature typically found only in the most expensive mined opals.

An Ethical & Sustainable Sparkle

Choosing a lab-grown opal is a choice you can feel good about. Our opals are grown above ground, completely bypassing the environmental disruption and ethical concerns associated with traditional mining. There is no destructive land use, no murky supply chains, just pure, beautiful opal created with a clear conscience.

Accessible Luxury

We offer these incredible gemstones at a more accessible price point than their mined counterparts of similar quality. Lab-grown opals make the breathtaking beauty of this unique gem available to more people and for more types of jewelry, allowing you to own a piece of rare beauty without the rare price tag.


With lab-grown opal, you no longer have to choose between breathtaking beauty and practical durability. You get the fire of a rare gemstone with the resilience for everyday life. A modern, ethical, and accessible treasure designed to last a lifetime.

How Our Lab-Grown Opal is Made

Our lab-grown opal, also known as synthetic opal or man-made opal, is a marvel of science, capturing the dazzling beauty of natural opal in a controlled environment. The result is a gemstone material with spectacular, consistent color and fire. While created in a lab, it shares the same fundamental composition as its natural counterpart: silica.

Lab-grown opal provides a brilliant and ethical alternative to mined opal. It offers not only affordability but also enhanced durability for creative projects. Unlike natural opal, which can be prone to cracking or crazing, our opal is stabilized with a polymer. This special impregnation process makes the material much stronger and easier to work with, perfect for jewelry, ring making, and other crafts. Please note, because of this polymer stabilization, the material cannot be exposed to the high heat of activities like glassblowing.

The Creation Process

Growing opal is a slow and precise art that mimics nature's own method, refined by science. The entire process, from start to finish, can take over a year to complete.

Step 1: Forming the Foundation

The journey begins with a solution of microscopic silica spheres suspended in water. This solution is the basic building block of opal. Nothing can be rushed here; the silica must be allowed to settle naturally.

Step 2: The Long Wait for Color

Over several months, these tiny silica spheres gradually sink and stack themselves into a highly ordered, tightly packed lattice. It is this perfectly uniform structure that gives opal its unique magic. As light passes through, the structure acts like a prism, diffracting the light and splitting it into a vibrant, dancing spectrum of color. This phenomenon is known as "play-of-color."

Step 3: Stabilization and Hardening

Once the silica structure is perfectly formed, the water is slowly and carefully removed. The material is then infused with a polymer to add strength and stability. This crucial step enhances the opal's durability, making it resistant to impact and cracking. The block is then allowed to fully harden into a solid mass.

Step 4: Revealing the Beauty

The rough block of lab-grown opal is now ready to be transformed. Just like a natural gemstone, it is skillfully cut, shaped, and polished to reveal the breathtaking patterns and colors locked inside. This process results in a stunning material ready for endless creative applications.
