Frequently Asked Questions
What is lab-grown diamond?
Lab grown diamond (also called a lab created diamond) is a real diamond made in a laboratory using either the CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) method. Lab grown diamonds share the same chemical, physical, and optical characteristics as natural mined diamonds, making them identical in appearance and quality.
What are lab-grown gemstones?
Lab grown gemstones are real gemstones created in laboratories instead of being mined from the earth. They include lab grown ruby, sapphires, emerald, Alexandrite, and spinel, produced using advanced techniques such as the Czochralski Method (Czochralski Pulled) and the Hydrothermal Method. Lab grown ruby, sapphires, and emerald share the same chemical, physical, and optical characteristics as natural mined gemstones.
What is ethical fine jewelry?
Ethical fine jewelry refers to jewelry created with a strong commitment to responsibility and sustainability throughout the entire production process. It uses ethically sourced materials, such as lab grown diamonds, lab grown gemstones, and recycled metals like gold, silver, and platinum, which help reduce environmental impact and avoid the negative effects of traditional mining.
In addition, ethical fine jewelry emphasizes fair labor practices, eco-friendly manufacturing, and sustainable design to ensure that every piece is not only beautiful and durable but also made with respect for people and the planet.
