Siara by Ark is an Australian fine jewellery brand specialising in IGI-certified lab-grown diamonds at true wholesale pricing. Every piece is made to order in solid gold, handcrafted by skilled artisans, and delivered with a Lifetime Warranty. We offer genuine one-on-one support from real diamond specialists — not a sales floor. You shop at your own pace, with no pressure, and the confidence that you're getting the best value available.

Lab-grown diamonds are graded using the exact same 4C standards as mined diamonds — Cut, Colour, Clarity, and Carat. At Siara by Ark, all our diamonds are IGI-certified, meaning every stone has been independently assessed and graded. You get the same brilliance and fire, at a significantly better price point, and with the peace of mind of being 100% conflict-free.

Every Siara ring is made to order. Standard production time is approximately 2 weeks from when your order is confirmed. For custom or bespoke designs, timelines may vary depending on complexity — we'll confirm the expected timeframe during your design consultation.

Moissanite was first discovered in 1893 by a French scientist named Henri Moissan, who later won the Nobel Prize in Chemistry. Natural moissanite is incredibly rare, so moissanite available today is laboratory-created. Composed of carbon and silicon,the Moissanite crystal is one of the hardest and toughest known elements on earth, making it extremely resistant to scratching, chipping and breaking. Possessing fire, brilliance, and luster that far surpasses even that of a diamond, Moissanite twinkle, and sparkles unlike any gemstone on earth.

As a boutique jeweler, we source and certify each piece specifically for you, ensuring the freshest inventory and best value. Your IGI certificate will be ready before shipping.
