Our Values

At One Mo Diamond, jewellery is more than beauty — it’s legacy, responsibility, and soul.

Every piece is created by master artisans with over 25 years of experience, many of whom have worked side by side in our workshop for decades.

We are a family-owned business, run by a husband and wife who grew their craft with passion and precision.

Today, even our children take part in the process — making it truly a generational journey, shaped by trust and love.

Our diamonds are sourced exclusively from verified and trusted exchanges. Every stone is ethically acquired and carefully selected for its brilliance and fire.

We use only certified and pure gold. Each piece is independently hallmarked by an official Assay Office, guaranteeing full traceability, authenticity, and compliance with EU standards.

We never produce hollow jewellery. Our pieces are solid, strong, and built to last — with generous gold weight and exceptional finishing.

Each piece is meticulously crafted and polished by hand — with special attention to every angle and surface.

Our goal is to make each diamond shine like a mirror and every detail reflect our dedication to excellence.

From the first sketch to the final polish, every creation reflects who we are: honest, devoted, and endlessly passionate about fine jewellery.

Jewellery Care

To preserve the lasting beauty of your One Mo Diamond jewellery, we recommend following these care guidelines:

• Avoid contact with harsh chemicals such as perfume, cleaning agents, and chlorine, which can dull metals and damage gemstones.
• Remove jewellery before swimming, showering, or exercising to prevent moisture and impact damage.
• Store your pieces separately in a soft pouch or lined box to prevent scratches, especially with softer stones.
• Clean your gold or platinum jewellery regularly with a soft, lint-free cloth to restore shine.
• For gold and diamonds, you can use warm water with mild soap and a soft brush for a deeper clean.

Caring for Specific Gemstones

While diamonds, sapphires, and rubies are durable, other gemstones require gentler handling:

• Emeralds, tourmalines, topazes, garnets, citrines, aquamarines: Avoid ultrasonic cleaners or sudden temperature changes. Clean with a soft damp cloth only.
• Pearls (all types): Extremely delicate and organic – avoid chemicals, perfumes, and excessive moisture. Wipe gently with a soft cloth after wear and store flat in a breathable pouch.

With the right care, your jewellery will continue to shine for generations.
