ABOUT TJ GOLD & DIAMOND

A perfect place for your precious items

At TJ Gold & Diamond, we believe fine jewellery should be beautiful, honest and within reach. We're a New Zealand diamond merchant and jewellery manufacturer, creating your dream piece in-house — from engagement rings to custom designs — at prices the big retailers can't match. Based in Auckland, with a second facility in Houston, Texas, we design and handcraft everything ourselves. There's no middleman and no retail markup — just skilled jewellers making your piece from start to finish. Trusted by thousands of New Zealanders, we offer both lab-grown and natural diamond engagement rings, and we back every lab-grown diamond we sell with a buyback guarantee. Because we manufacture in-house, you receive premium quality that's hard to match on a big-box retailer's shelf. We're also Auckland gold buyers — we test and value your gold in front of you and pay based on the live gold price. Explore our collections, and if you have any questions, we'd love to hear from you — get in touch any time.
