FAQ

Thank you for visiting us. Our jewelry is entirely handcrafted in Italy, in an intimate studio located near Milan, surrounded by nature. We are a team of two, Adele Piatti and Roberto Ortenzi, and we design and make all Sideræ jewelry pieces, start-to-finish. Visit our Crafting Approach page to find out more.

Liquid Setting is our signature technique, where gemstones are set directly into molten gold. This method allows gold and stones to interact freely, finding their own harmony. Each Sideræ creation emerges from that unrepeatable moment where fire, instinct and expertise meet. The result? Truly one-of-a-kind pieces, defined by unique variations, organic textures and fluid shapes that bear the subtle, singular marks of their creation.

Check out our Liquid Setting page to discover more.

At Sideræ, we work exclusively with 18K gold. This alloy, rich with 75% pure gold, strikes the perfect balance: noble and luminous, yet strong enough to withstand the intensity of our process. This gold content also makes the alloy very low tarnish. We don’t use white gold or platinum; only 18K gold truly flows and responds to the dance of fire that defines our craft. We can also work in Fairmined Gold on request, please contact us for a quote.

These three gemstones—sapphires, rubies and diamonds—are our "brave companions," the only stones tough enough (8-10 on the Mohs scale) to withstand our molten gold process. While emeralds and any other soft semi-precious stones are stunning, they simply can't handle the intense heat of our Liquid Setting technique.  Sapphires and rubies bring vibrant color, while diamonds add eternal sparkle. We lovingly call them our "heat warriors" because they dance with fire, remaining strong through every stage of our process while preserving their natural beauty.

We offer a curated selection of Ready to ship pieces online, but the majority of our rings are made to order in 8-10 weeks. We recommend checking availability before placing your order, especially if you have a special occasion or deadline in mind.

Sideræ jewels are crafted for everyday life, but we recommend removing them during physical activities—such as exercising or manual work, gardening, arts and crafts—to protect the stones and settings. This helps prevent accidental knocks and shields your jewelry from chemicals and chlorine, which can damage both gold and gemstones.

Our collection includes delicate, lightweight pieces as well as bolder, more sculptural designs. Some styles naturally require more care than others. If you're unsure which piece suits your daily rhythm, feel free to reach out—we’re happy to offer thoughtful, honest guidance.

Treat your Sideræ jewels with care, and they’ll stay beautiful for years to come. Store each piece separately in the soft pouch or box provided, separating each item to protect them from scratches. To clean, a soft lint-free cloth is often all you need—but for a deeper cleanse, warm soapy water and a soft brush will gently lift any hidden dust or dirt.

Your order will be carefully packaged to ensure it arrives safely and beautifully.
Each piece of jewellery is placed inside a branded Sideræ jewellery box or a high-quality pouch, and shipped in a discreet postage box and mailing bag.

If the shipping address differs from the billing address, we will treat your order as a gift. In this case, no receipt will be included in the package; instead, the receipt will be emailed to you separately.

For the most accurate fit, we recommend visiting a reputable jeweller to have your finger professionally measured. Finger size can vary throughout the day and with temperature, so it’s helpful to be measured more than once for the best result.

You’ll find detailed guidance and tips on our dedicated Ring Sizing Guide, including how to measure at home and what to consider before ordering. If you need extra help, we are always happy to advise—just get in touch!

Unfortunately, we are unable to resize rings after purchase. We recommend carefully checking your size before ordering—please refer to our Ring Sizing page for guidance. If you are unsure of your ring size or concerned about ordering the wrong size, please email clientcare@siderae.com and we will assist you.

We provide a detailed size conversion chart on our website to help you find your US ring size based on your local sizing system. On any product page, click the SIZING GUIDE button (above Add to Bag). It opens our Size & Fit chart with international conversions (UK, EU/France, Italy).

We offer personalisation of our existing designs by selecting different gemstone colours, depending on availability. At this time, we do not customize stone sizes or precious metal alloys. 

We can assist you in exploring our collections and the available options to make an existing design more personal to you. Please contact us to discuss your preferences or to learn more about our current gemstone choices.

We can’t physically incorporate gold from your vintage jewelry into your new Sideræ piece. It isn’t just a policy—the reason is technical: because we can’t verify the precise purity and composition of externally supplied gold, using it could undermine the structural integrity of your Sideræ piece. Additionally, our special Liquid Setting process requires carefully controlled materials to ensure the quality and longevity of every creation.

At this time, we are unable to incorporate external or vintage stones into our jewelry. This is to ensure the quality and integrity of every Sideræ piece.
