In our online store, quality isn’t just a promise: it’s a real, certified commitment. All of our black and gray zirconium rings, with or without lab-grown diamonds, have been carefully selected, manufactured, and inspected under strict quality controls. We want every customer to be confident that they are purchasing a safe, authentic, and long-lasting piece of jewelry.

✅ Lab Diamond Certification

All of our diamond rings include a certificate of authenticity, which guarantees:

• That the diamond is created in a laboratory, with the same physical, optical and chemical properties as a natural diamond.
• Its degree of purity (clarity) according to recognized gemological standards.
• Its level of whiteness/color, to ensure exceptional brightness and impeccable aesthetics.

The lab-grown diamonds we offer are a sustainable, ethical, and more affordable option, without sacrificing the beauty and quality that characterizes precious stones.

🔬 Material Analysis and Safety

Our zirconium rings have undergone laboratory testing to certify their dermatological safety and composition. We can guarantee that all our products are free of heavy metals and toxic elements, such as:

• Cadmium
• Nickel
• Lead

This makes them safe even for sensitive skin or people with allergies, without compromising the ring’s strength, shine, or durability.

📄 What does the certificate include?

With each purchase you will receive a printed certificate, which includes:

• Diamond technical details
• Ring material composition
• Tests carried out
• Confirmation of absence of hazardous metals
