The Foundations of a Diamond
Cut
Cut defines how a diamond interacts with light — its brilliance, fire, and life. A well-cut diamond reflects light internally and returns it through the top, creating that unmistakable sparkle. Even the finest diamond can appear lifeless if the cut is poor.
Colour
Colour measures the presence of natural tint within a diamond. The most sought-after diamonds are colourless, allowing light to pass through effortlessly. Subtle variations can influence both appearance and value.
Clarity
Clarity refers to the natural characteristics formed within the diamond during its creation. Most are invisible without magnification and do not affect the overall beauty of the stone.
Carat
Carat is the weight of a diamond — often associated with size, but not the full story. Two diamonds of equal carat can appear very different depending on their cut and proportions.
Certification
Every diamond should be independently assessed and verified. Certification provides an objective evaluation of a diamond's characteristics, ensuring transparency and confidence in your purchase.
Our Philosophy
A Diamond is More Than A Purchase

— SPADAVECCHIA DIAMONDSA Lifelong Passion for Diamonds
Spadavecchia Diamonds was founded from a lifelong passion for diamonds, gemstones, and jewellery. We have been working with diamonds and precious stones since 2011, developing a deep appreciation for quality, craftsmanship, and the emotion that a beautifully chosen piece can bring.
The name Spadavecchia comes from Italian heritage — Spada meaning sword and Vecchia meaning old — symbolising strength, tradition, and legacy. These values shape the foundation of Spadavecchia Diamonds: honouring timeless beauty while bringing a modern approach to fine jewellery.
We believe everyone should have access to exceptional diamonds and precious gemstones. Luxury should not feel out of reach — it should be transparent, accessible, and designed to celebrate life's meaningful moments.

Frequently Asked Questions
Questions & Answers
Everything you need to know about diamonds, our process, and what to expect when working with us.
Natural diamonds are formed deep within the earth over billions of years under intense heat and pressure. Each stone is a rare product of nature, carrying a unique geological history that makes it truly one of a kind.
Lab-grown diamonds are created in advanced laboratories using technology that replicates these natural conditions. They are physically, chemically, and optically identical to natural diamonds. The key difference lies in origin and rarity. Natural diamonds are finite creations of nature, while lab-grown diamonds are the result of modern innovation, offering the same beauty and brilliance through a different journey.
At Spadavecchia Diamonds, we offer both — allowing you to choose between the timeless story of nature or the precision of contemporary craftsmanship.
At Spadavecchia Diamonds, each piece is prepared with exceptional care and attention to detail.
We accept returns within 7 days of delivery for items that are in their original, unworn condition and accompanied by all original packaging and certification. Items must be free from damage, scratches, or any signs of wear.

Yes. Our private appointments offer a personalised experience where you can explore our diamonds or discuss a bespoke creation. We take the time to understand your vision and guide you with expertise, care, and attention to detail.
Ready-to-ship pieces are typically dispatched within a few business days. Bespoke and made-to-order creations usually require additional time to complete. Estimated timeframes will be provided at the time of purchase.
To maintain your jewellery’s brilliance, we recommend gentle cleaning with warm soapy water and a soft brush. Store each piece separately to avoid scratches or contact with other jewellery.
Avoid exposure to harsh chemicals such as perfumes, cleaning products, and chlorine, and remove your jewellery during strenuous activities, exercise, or heavy lifting.
Our diamonds are sourced through a trusted global network of suppliers who follow internationally recognised standards of responsible sourcing.
Natural diamonds are obtained from established diamond-producing regions, while our lab-grown diamonds are created using advanced technology under carefully controlled conditions.
At Spadavecchia Diamonds, we are committed to ensuring every stone is selected with care, integrity, and respect for both people and the environment.
