We’re introducing GIA verification for our highest quality DEF Loose stones first, to provide enhanced transparency and confidence for our customers. We will expand future verification to include additional color grades. 

GIA verification is the process of confirming the authenticity and quality of a lab-grown diamond. The GIA report represents the highest standard of reliability, consistency and integrity in diamond grading, and our approach to quality verification through GIA provides independent third-party assessment of our stones using a random sampling process. Starting with our DEF white round brilliant Loose stones, we will provide a statistically significant sample from each production run to be graded, ensuring the stones meet GIA’s stringent quality criteria for color, clarity and cut, allowing for the entire batch to be verified and sold as Lightbox stones.

As we continue to change our verification processes and provide detailed specifications based on the items you purchase, we want to ensure we are continuing to find ways to reduce our footprint. You will be able to print your specifications for every lab-grown diamond you purchase from our download page.

We found through our consumer market research and studies, that when choosing a diamond, buyers place more value on stone color and cut. Based on these preferences, we streamlined our lab-grown diamond offering to provide the best adjusted price on our D,E, F stones, while ensuring we provide an excellent value at VS+ quality.

The customer is at the core of all our decisions, and we see interest across all color grades, including GH and IJ. By offering all three options at various price points, we maintain competitive pricing, deliver the most value, and empower customers to choose the lab-grown diamond that best fits their preferences.

Each style of jewelry uses a different amount of metal for its setting, with the final price for the piece determined by this variable setting cost, plus the price of the stone.  

Lightbox lab-grown diamonds are created in our state-of-the-art laboratory in Gresham, Oregon, using 100% renewable wind energy. We remain committed to a long-term carbon reduction plan that will further cut down emissions across our entire value chain.
