Buy sustainable solitaire rings in Switzerland

Solitaire rings are the classics among engagement rings and have been impressing with their classic design for decades. The rings are characterized by a tasteful ring band on which a single gemstone is enthroned. A diamond is often used for this model as it has a beautiful fire and is particularly durable due to its hardness. But other types of stone, such as rubies and sapphires or aquamarines, are also ideal for solitaire rings. At SIGNUM, you will find a large selection of solitaire rings that capture the character of the classic ring in unique variations. So that you can wear a high-quality piece of jewelry, we make sure that our materials are well processed and fairly mined. We attach great importance to ensuring that all our pieces are made with sustainable gemstones, pearls and fair trade gold – this applies to both unique pieces and the bestsellers in our online store.

Occasions for solitaire rings from SIGNUM

There are various occasions to buy solitaire rings. The rings are particularly popular for engagements, but are also suitable as an anniversary gift or as a gesture when renewing wedding vows. The rings are also great for capturing special moments in life in a piece of jewelry: the birth of a child, the completion of training or the start of a new chapter. The rings are not always linked to a partnership. Heirlooms, for example, have a close family significance and are often worn as a reminder of deceased loved ones.

The solitaire ring as an engagement ring

Engagement rings and wedding rings are symbols of eternal love and a promise for a future together. Solitaire rings are undoubtedly the classics in this category. A solitaire draws all eyes to a single diamond. This is a timeless design that can be worn for a lifetime. At SIGNUM, we understand the importance of this moment and offer an exclusive selection of solitaire rings that are handmade and individually designed. Our models are classic and elegant and symbolize the uniqueness of the love that two people share. With a solitaire ring from SIGNUM, you are not only choosing sustainability, but also a masterpiece of goldsmithing.

Solitaire rings - the gemstones

Solitaire rings are suitable for all jewelry lovers who would like to wear a sparkle on their finger that is unobtrusive yet prominent. This is why many choose a diamond as their main stone, as it has an impressive fire and high durability. But color lovers can also adapt a solitaire ring to their personality. Colored stones such as tourmaline, sapphire or ruby can give the ring a unique touch and are a real eye-catcher on your finger. We know our way around colored gemstones and diamonds and therefore know exactly what is important when making a choice:

Everyday stress

Depending on how much you use your hands and therefore the ring on a daily basis, we recommend different stones – the reason for this is that some stones are harder than others and are therefore more or less suitable for your daily life.


Jewelry plays a major role in expressing style. We have many years of experience in making jewelry and advising customers, so we make sure that you get the ring that best suits your style and the stone you want.


Gemstones have different degrees of hardness and are therefore suitable for different types of setting and processing. Our goldsmiths set your desired stone in such a way that you can enjoy the piece of jewelry for years without the stone being lost or broken.


The purity of a gemstone is of crucial importance as it determines its optical clarity and brilliance. It also influences the monetary value and aesthetics of the stone by enhancing its color and luminosity.


At SIGNUM, we attach great importance to the origin of our materials. That is why we only use gemstones that are fairly traded and ecologically produced. These include old-cut diamonds and brilliant-cut diamonds as well as all kinds of colored stones. We want our jewelry to be worn with a clear conscience and to be produced under fair conditions.

We use these gemstones:

  • Old cut diamonds
  • Diamonds
  • Amethysts
  • Aquamarine
  • Heliodore
  • Morganite
  • Oregon Sunstone
  • Smoky quartz crystals
  • Rubies
  • Sapphires
  • Emeralds
  • Tourmalines
