A Bridge Between Worlds- From Sri Lankan Mines to Danish Integrity
At Zentha, we don’t just sell gemstones — we trace their journey from the heart of the earth to your hands. Born from a deep passion for authenticity and a commitment to ethics, our mission is to connect gem lovers with treasures that are as meaningful as they are magnificent.
Who we are
We are a boutique gem trading company based in Denmark (Sineklo ApS – CVR 40177973), with a sourcing heart in Sri Lanka, the legendary “Ratna Dweepa” — Island of Gems. Our founder, Liyanage Thanuja Ellawala, brings together decades of cultural insight, ethical sourcing relationships, and creative vision.
What makes us difference
• Direct Sourcing: We work closely with small-scale miners and trusted networks in Sri Lanka. This gives us access to premium, unheated, untreated gemstones — often before they ever reach global markets.
• Ethics First: All our gems are 100% natural and responsibly sourced. No synthetics. No unethical mining.
• Certified Danish Business: Operating from Denmark provides full transparency, consumer rights protection, and verifiable accountability for every order.
• Sapphire Focus: Our primary expertise lies in sourcing and evaluating Ceylon Sapphires, ensuring transparency in origin, treatment disclosure, and grading standards.
Our Vision
To become a globally trusted name in ethical gemstone sourcing, specialising in Ceylon Sapphires, built on a foundation of trust, craftsmanship, and transparency
A note from the founder
"Zentha is a reflection of my journey — rooted in Sri Lanka, living and building in Denmark, and reaching the world.I believe that buying a gemstone is not just a transaction. It’s a relationship — with nature, with history, and with the people who bring it to life. At Zentha, we honor that journey." — Liyanage Thanuja Ellawala
