Raw Herkimer Diamond Gold Plated April Birthstone Necklace

April's birthstone is the diamond, and Harfi interprets it through a raw Herkimer diamond — a naturally faceted quartz crystal with the clarity and sparkle of a diamond, worn close to the collarbone in a refined, minimal setting.
The necklace is part of Harfi's capsule jewellery system. The pendant is designed to slide on and off a compatible base chain, so you can swap it with other Harfi pendants — raw birthstones, semi-precious gemstones, initials, zodiac charms — without buying a new necklace each time. It is a considered approach to building a jewellery wardrobe without accumulation.
The setting is 18k gold vermeil, which means a thick layer of 18k gold over a sterling silver base. This is the construction detail that separates vermeil from gold-plated costume jewellery: the gold layer is substantially thicker, which is why it holds its finish through daily wear rather than fading within months.
Harfi works directly with artisan partners, removing the intermediaries that typically inflate the price of fine jewellery. The result is a piece that sits in the demi-fine category — quality materials and construction — at a price point that reflects the supply chain rather than the margin.

About Our Brand Harfi
At Sophelia, the bonds between loved ones have always meant everything to us. We believe the moments that matter most in life aren’t always the biggest ones – they’re also the small, quiet reminders that someone is thinking of you.
No matter where you are in the world, we’re here to help you show someone that they matter. Whether it’s a birthday, a graduation, or simply a thank you, it’s about making sure they feel seen, appreciated, and close to you – even from miles away.
At our heart, we’re a company built on sharing in joy. With two beautiful daughters at the centre of our world, we’ve always been reminded how powerful even the smallest gestures can be. A thoughtful gift isn’t just something you give – it’s a way of saying ”I’m with you, I’m proud of you, I’m thinking of you”. And your loved one can think of that every time they wear their jewellery.
That’s what Sophelia is about. Not just jewellery, but the feeling behind it – the connection it carries, and the moment it creates when it’s opened.
