With decades of expertise, Hamilton & Co. transforms these gemstones into works of art, marrying technical precision with a profound appreciation for the emotional resonance of colour.
RESPONSIBLE SOURCING
At Hamilton & Co., we ensure every diamond and gemstone is ethically sourced through trusted, transparent channels. We partner with suppliers committed to strict environmental and social standards, ensuring conflict-free stones mined with respect for people and the planet. We actively support high industry standards to protect human rights, preserve sensitive lands, and foster sustainable local economies.
PERFECTING BRILLIANCE
Our diamonds are expertly cut and polished in Jaipur, a historic jewellery hub where best-in-class multidisciplinary expertise combines with cutting-edge technology. Skilled artisans bring incredible accuracy and artistry to every stone, revealing its full brilliance and beauty. We are committed to supporting local communities by fostering sustainable development. Additionally, we source select polished diamonds from trusted suppliers who meet rigorous standards of traceability, quality, and ethical practices.
QUALITY STANDARDS
In all its jewelry, Hamilton & Co. uses only diamonds procured in accordance with the Kimberley Process. Established in 2003 following a United Nations General Assembly resolution, this process ensures that “conflict diamonds” do not enter the rough diamond market.
All preselected stones meet these internationally recognized standards of excellence. Hamilton & Co. selects only natural diamonds graded from D (colorless) to I (near colorless) on the diamond color scale. The stones are carefully chosen from the highest clarity grades—from IF (Internally Flawless) to SI1 (Slightly Included). All diamonds used in our jewelry have an “excellent” or “very good” cut grade. Our in-house experts meticulously focus on symmetry, polish quality, and cut finishes to reveal the full sparkle and fire of each gemstone.
HANDCRAFTED EXCELLENCE
Defined by a heritage of exceptional craftsmanship, Hamilton & Co. creations are meticulously handcrafted in the foremost specialist workshops in Jaipur, a city renowned for centuries as a global centre for fine jewellery making. Our master artisans seamlessly combine time-honoured techniques passed down through generations with cutting-edge technologies, reflecting an unwavering commitment to innovation. Our collections exemplify this artistic legacy, reaffirming Hamilton & Co.'s mastery in capturing the vibrant allure of coloured gemstones.
