At A. Gatsos Jewellery, a tradition that began in 1997 meets today’s revolution in the art of goldsmithing and silversmithing. Alexandros Gatsos and Effi Natsiou, driven by a passion for innovation, invite you to discover up close the allure of Lab-Grown Diamonds.

Why is everyone talking about Lab-Grown Diamonds?

These are not imitations, but real diamonds. They have the same hardness, the same chemical composition, and the same eternal brilliance as mined diamonds. The difference? They are created in a laboratory using cutting-edge technology, offering an ethical, sustainable, and significantly more affordable alternative—without any compromise in quality.

Certified Excellence (IGI & GIA)

Trust is the foundation of every valuable relationship. At Gatsos Jewellery, every lab-grown diamond they select comes with international certification (IGI or GIA).
This means each stone has its own “identity”: its Carat weight, Color, Clarity, and Cut are precisely recorded. This gives you official assurance that you are holding a gemstone of top-tier standards.

The proposal moment: A “Yes” signed by Gatsos

A marriage proposal marks the beginning of your story. Imagine a breathtaking solitaire ring, featuring a larger and more brilliant diamond than you ever dreamed of—made possible by the value of lab-grown diamonds.

  • Custom-made design: Alexandros Gatsos creates the ring exactly as you envision it.
  • Consultative experience: They guide you in choosing the perfect stone to seal your promise forever.
