Sian Evans uses vintage diamonds throughout the Sands of Time collection. These diamonds come from jewellery pieces that have been recycled. The old table cuts Sian uses were all cut by hand and were designed to twinkle in low light, gas and candle light. They have a softer sparkle than modern diamond shapes and cuts. By choosing to have a ring made with a vintage diamond, you are choosing a sustainable future, by-passing newly mined and cut stones and giving a new life to an old stone made by nature and cut by a lapidary, perhaps up to 200-300 years ago .
