While lab-grown diamonds exhibit the identical optical, physical, and chemical properties as natural diamonds, their core difference is their origin and the time they took to form. Natural diamonds take billions of years to form and are considered a finite resource.
Both natural diamonds and lab-grown diamonds vary in their diamond grading. Natural diamonds are incredible feats of nature and are considered a more traditional choice. A natural diamond is often considered a status symbol and is more likely to hold its value over time, but the "better" option depends on your unique needs, style, and budget.
Natural diamonds are grown deep in the earth from carbon deposits that withstand extreme heat and pressure over billions of years. They are excavated from mines worldwide, including Australia, South Africa, India, and more. Zales is dedicated to ensuring our natural diamonds come from 100% conflict-free sources.
Neither is inherently higher quality, as both lab-grown and natural diamonds are available in a range of colors, cuts, clarity, and carat weights.
Yes, we provide the same warranties and service plans for both natural and lab-grown diamonds.
Your natural diamond will be accompanied by an independent laboratory report detailing its "4 Cs" - cut, color, clarity, and carat weight.
Because lab-grown diamonds have the same optical, chemical, and physical characteristics as natural diamonds, they cannot be distinguished even with a professional loupe under 10x magnification. That's why Zales' lab-grown diamonds are inscribed with "lab-grown diamond" on the girdle.
A natural diamond has traditionally maintained its value. Since they are a finite resource, their rarity suggests they will maintain their value or increase in value as they become harder to find. People might want to pass jewelry made with natural diamonds down through generations or reuse natural diamonds for new pieces of jewelry.
