Pippa Small’s grey Tamadun necklace is handmade by artisans of the Turquoise Mountain Foundation – a non-profit organisation founded by HRH Prince of Wales in 2006 to support and employ young people of Afghanistan in creative jobs. It’s plated with 18kt gold and shaped with hammered teardrop pendants and striking centre stones of agate – a naturally occurring stone that means each piece has a unique finish. Let it be the statement centre piece of an all-white outfit at your next special occasion.
