FAQS

Jewelry Fit and Care

Are lab-grown diamonds real? Does Gemmy Jammy offer lab grown diamond jewelry?

Yes. They are real diamonds.
Lab grown diamonds have the same physical, chemical, and optical characteristics as natural diamonds, as well as the same fire, scintillation, and sparkle. They are real diamonds. Lab grown diamonds are nearly impossible to differentiate from natural diamonds with the naked eye.
Additionally, lab-grown diamonds offer a more environmentally friendly alternative to mined diamonds. Their production typically requires less energy, water, and land disruption, helping to reduce environmental impact.

GemmyJammy offers an extensive collection of stunning lab grown diamond jewelry (lab grown diamond necklaces, lab diamond earrings and rings and so on).

Why is my white gold ring starting to turn yellow in color?

The yellow you are seeing on your ring is a completely normal condition that is inherent with the daily wear of white gold jewelry. To achieve its white color, pure gold is often mixed with zinc, palladium, or nickel alloys. White gold jewelry is also dipped in rhodium, giving it a brilliant, chrome-like color, while also protecting it from scratching.
