Our Diamonds

Our dedication to excellence begins with our sourcing practices, ensuring that each diamond we offer comes from reputable suppliers who share our values of ethical standards and superior craftsmanship.


Natural Diamonds

Timeless Beauty and Unique Origin

Natural diamonds are formed over billions of years deep within the Earth’s mantle, making each one a unique marvel of nature. At Diamond Gallery, we source our natural diamonds from reputable mines that adhere to strict ethical and environmental standards. Our natural diamonds are carefully selected for their exceptional quality and are available in a variety of cuts, colours, and sizes.

Certified and Authentic

Each natural diamond we offer is certified by leading gemological laboratories such as GIA (Gemological Institute of America). These certifications provide an unbiased evaluation of the diamond’s 4Cs – Carat, Cut, Colour, and Clarity – ensuring that you receive a gem of verified quality and authenticity. Our natural diamonds are perfect for those who appreciate the rarity and timeless beauty of a gemstone created by nature.


Lab-Grown Diamonds

Innovation and Sustainability

Lab-grown diamonds represent the perfect blend of innovation and sustainability. Created in a controlled laboratory environment using advanced technological processes, these diamonds are chemically, physically, and optically identical to their natural counterparts. At Diamond Gallery, we partner with reputable laboratories that produce high-quality lab-grown diamonds, offering an ethical and eco-friendly alternative.

Affordable Excellence

Lab-grown diamonds provide exceptional value, often at a lower price point than natural diamonds of similar quality. This allows you to choose a larger or higher-quality stone within your budget. Our lab-grown diamonds are also certified by renowned gemological institutions, ensuring that you receive a diamond that meets the highest standards of excellence and integrity.


Commitment to Quality

We understand that purchasing a diamond is a significant investment, and we strive to provide only the best.

Our diamonds are meticulously selected based on stringent criteria to ensure they meet the highest standards of brilliance, cut, and clarity. We work exclusively with suppliers who have a proven track record of delivering exceptional diamonds, allowing us to offer you gems that are not only stunning but also of the utmost quality.


Ethical Sourcing

Ethical practices are at the heart of everything we do.

We are dedicated to ensuring that all our diamonds are sourced responsibly, adhering to the highest ethical standards. Our suppliers are committed to the Kimberley Process, an international certification scheme that prevents the trade of conflict diamonds. This ensures that every diamond you purchase from Diamond Gallery is conflict-free and ethically sourced, giving you peace of mind and confidence in your choice.


Trusted Suppliers

Our relationships with trusted suppliers are built on a foundation of integrity and mutual respect.

We collaborate with some of the most reputable diamond manufacturers and dealers in the industry, who are known for their excellence in diamond cutting and their adherence to fair labor practices. This partnership allows us to provide you with diamonds that are not only breathtakingly beautiful but also come with a guarantee of ethical origin.


Extensive Selection

At Diamond Gallery, we offer an extensive selection of diamonds, including both natural and lab-grown options.

Each diamond is carefully inspected and certified by leading gemological laboratories such as GIA (Gemological Institute of America). This certification provides an unbiased evaluation of the diamond’s quality, ensuring that you receive a gem that meets our rigorous standards.

How To Measure

  1. Grab a tape measure, length of string or strip of paper.
  2. Wrap it around the finger you'll wear your ring on—if you’re creating a ring stack, consider where on your finger the ring will sit—and mark the place where it joins.
  3. Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart above to match the measurement to the closest ring size.
  1. Choose a ring that already fits your finger well.
