While major achievements call for jewellery that feels just as meaningful, finding beautiful, quality pieces at an affordable price can often be harder than it is satisfying. When choosing engagement rings, anniversary gifts or other things to mark a life-changing event, it can be tricky to decide between searching for something beautiful and keeping to your budget. In particular, selecting diamonds can make the choice intimidating. You don't want to settle for less since you'll have it for years, but you also don't want to overspend or second-guess yourself every time you look at the piece. Here's where we change the conversation; since 1945, Shiels has become Australia's top family-owned-and-operated retailer with the biggest jewellery range at unbeatable prices. We've always maintained that everyone should have access to pieces that are both meaningful and affordable. We make celebrating big moments possible without losing out on value or quality. And because our in-house jewellery hunters search the globe for designs like G-Shock GA100B-4A that you won't spot just anywhere else, you can be confident your piece will feel special.

We're all about versatility, and we have an extensive collection that caters to every taste and occasion. If you're searching for the perfect engagement ring, our variety of styles spans from timeless solitaires to beautiful princess-cut pieces. For daily wear, you can select pieces made from precious metals, including silver and gold in yellow, white or rose tones. If you're mindful of your budget without compromising on design, we offer 1-, 2- and 3-carat natural and lab-grown diamonds for affordable brilliance. Blending fashion with functionality, our watch collection includes pieces from global brands like Casio, Citizen and Seiko. And if you want gemstone pieces or charm bracelets for loved ones' birthdays, along with lockets for baptisms and christenings, we have what you need. We have options suitable for these celebrations and much more. With us, you aren't just buying jewellery and watches because you're investing in pieces that mark life's defining moments and speak to your individuality without the high price tag. So, if you're still looking for Luminesce Lab Grown 1/3 Carat Princess and Taper Cut Diamond Ring in 9ct Yellow Gold, 9ct Yellow Gold Silverfilled Thin Wall 2.9mm X 70mm Golf Bangle or Timex Chicago TW2V01600, you can make us your go-to destination for every event and celebration you can think of.
