Frequently Asked Questions
Lab-created diamonds are the ethical, green, and responsible choice when it comes to modern fine jewelry. These diamonds are virtually indistinguishable from earth-mined diamonds, last just as long, and offer better value.
As part of our efforts to contribute to a greener environment, Stefano Navi primarily sources fair-mined, recycled, and re-refined metals in our jewelry.
Once these metals are refined, they are in essence “melted”, or brought back to their purest form. They maintain the same high-quality element as newly mined metals, but without the pollution and harm to our planet.
We do offer our lab-grown diamonds to be purchased individually, without the setting, and extend the same complimentary 30-day return service for this option.
We do offer our full range of precious metal settings without our diamonds, and extend the same complimentary 30-day return service for this option. In cases where there are smaller diamonds on the setting, the setting will be shipped in a semi-mount state, without the center diamond but including the smaller diamonds.
One of the ideas behind the Stefano Preferred offer is to allow you to propose now and worry later. This option provides you a timeless setting with a certified lab-created diamond, allowing you the flexibility to choose your ideal setting with your loved one at a later time. We accept exchanges for up to 180 days under this program, affording you the opportunity to carefully create your custom ring alongside your partner.
All of our lab-created engagement ring center diamonds are certified by IGI (International Gemological Institute), which is internationally recognized; certification will be provided upon purchase. While our smaller stones and other jewelry may not carry a certificate, we pride ourselves on our loose diamond expertise, and meticulously choose every diamond that is incorporated into our jewelry.
Our loose diamond inventory is constantly being updated. We advise you check back often to see if your desired diamond is on our site. If you have something specific in mind, please contact us in order to create your desired jewelry piece through our bespoke experience.
Lab-grown diamonds and earth-mined diamonds are essentially made of pure carbon. The only difference between them is that earth-mined diamonds contain trace amounts of nitrogen. Therefore, the very subtle molecular difference between the two can only be detected by trained gemologists using the specific, advanced machinery. Otherwise, the two types of diamonds are virtually indistinguishable, even to a jeweler using a magnifying loupe. A Stefano Navi diamond will always appear the same as an earth-mined diamond, both to the naked eye and in a routine jeweler’s inspection.
We offer a lifetime warranty on our full range products, including bespoke designs. Visit our Lifetime Warranty page to learn more.
All of our rings are handcrafted in our New York facility. We cast each piece into your desired precious metal in order to ensure the purest setting, free of porosity.
Stefano Navi’s lab-grown diamonds are all created using the CVD (chemical vapor deposition) method or the HPHT (high-pressure high-temperature) growing method. Both of these methods create diamonds that are virtually indistinguishable from earth-mined diamonds.
