Yes - lab-grown diamonds (also known as lab diamonds) are chemically identical to mined or natural diamonds. They have the same beauty and are an extremely popular choice.

Laboratory diamonds have the same chemical and physical properties as mine diamonds. Visually and structurally, they are indistinguishable - they have the same brilliance, the same fire and the same durability.

By all means! We know that many of our pieces of jewelry are intended as surprise gifts, for a proposal for example. That's why we send your order in inconspicuous packaging that doesn't reveal what's inside.

Yes, at Stellini we offer free worldwide shipping on all orders, including engagement rings with diamonds. You can store conveniently online and add your desired piece directly to your shopping cart.

Shipments outside Switzerland
Most of our shipments are sent as DDP (Delivery Duty Paid). This means that import duties and taxes are usually paid by us.

However, in some countries it is not possible to pay these charges in advance as the sender. In such cases, local taxes or customs duties may apply, which we unfortunately cannot cover.

For detailed information, please take a look at our shipping page or contact your local customs office.

Stellini Diamonds offers a lifetime manufacturer's guarantee on all our rings - including engagement rings, giving you confidence and peace of mind with every purchase. For all other jewelry, such as earrings, necklaces, pendants, bracelets and more, we offer a 2-year manufacturer's warranty.

No problem! At Stellini, you receive a free size adjustment for engagement and wedding rings, which you can take advantage of within the first 60 days after your ring is finished. The possibility of customization depends on the design and the metal used.
