Frequently asked questions
Our lab-grown opal is cultivated over approximately a year in a controlled laboratory setting, replicating the properties of natural opal. With at least 80% silica content, the process creates a rich opal color and vivid fire that are unmatched elsewhere. Our lab grown opal beautifully reflects the vibrant allure of Australian opal, known for its exceptional color richness.
The main chemical difference between lab-grown and natural opal is their formation and water content. Both are predominately made of silica, but natural opal contains water and forms over millions of years with impurities and irregular structures. Lab-grown opal replaces the water content with resin and is created in about a year under controlled conditions, resulting in a more uniform structure and consistent silica distribution. This resin and silica matrix results in more durable and consistently vibrant opals.
Creating opals in a controlled laboratory setting reduces the need for large-scale mining operations, which can lead to habitat destruction, soil erosion, and high energy consumption. Additionally, lab-grown opals require fewer resources, such as water and fossil fuels, minimizing their carbon footprint. This eco-friendly approach ensures that these opals maintain the beauty and properties of natural opals without the environmental strain associated with traditional mining practices.
Our lab-grown opals are sourced from a reputable, globally recognised company that was featured on Forbes’ list of the World’s Best Regarded Companies in 2019. This trusted manufacturer is known for its strict production controls and adherence to international standards. They prioritise sustainability by focusing on eco-conscious production processes that minimize environmental impact.

The ring is more beautiful in person! My husband loves it. The size fit my him also which is a problem we have had other places. It's a beautiful quality ring. The packaging was great but the post office here where I live is always a mess so that's not the sellers fault.

TLDR: Product - 10/10, Customer service 1000000/10
I ordered this ring for the significant birthday of a long-time friend. It arrived on time and was absolutely perfect for my friend. Or so I thought...
Slight snag: my friend's husband had told me the wrong ring size! My friend contacted Sentient Designs and they practically bent over backwards to help her get a replacement in the correct size. She is so happy with her ring and says that not only is it pretty, but it is also comfortable to wear. I would highly recommend this company.
