How do I find out my partner's engagement ring size?

Finding the right ring size for an engagement ring is easier than you might think. If you have a ring that fits your partner, measure the inner diameter with a ruler or use a ring sizer. Alternatively, you can briefly slip the ring onto your own finger and mark where it sits – then measure this mark with a strip of paper.Without an existing ring, you can simply wrap a thread or strip of paper around the desired finger, mark the overlap, and compare the length with our ring size chart on fejn.com (Here you will find the overview).If you're unsure, friends or family members can often subtly help – while strolling, shopping, or by asking clever questions. This way, the surprise is guaranteed to be a success.

Does fejn offer simple and sustainable engagement rings?

Yes – at fejn jewelry you'll find sustainable, simple, and timelessly elegant engagement rings, crafted with meticulous attention to detail. Each ring is made from recycled 14-karat solid gold and set with lab-grown diamonds, emeralds, or ethically sourced gemstones. Our designs are minimalist, modern, and deliberately understated, making them a perfect fit for any style – sustainable, fair, and beautiful.

What makes fejn's engagement rings sustainable?

Our engagement rings are particularly sustainable because they are made entirely from recycled 14-karat gold. We exclusively use lab-grown diamonds and emeralds – so-called Laboratory Grown Diamonds/Emeralds– which are produced without environmentally harmful mining. Each ring is individually made to order to avoid overproduction and conserve resources.The rings are handcrafted using traditional methods under fair working conditions in certified workshops, and the designs are created in our Cologne studio. With a fejn engagement ring, you are choosing conscious luxury that unites love, sustainability, and responsibility.

Can the ring size of sustainable engagement rings be changed?

Ring resizing is generally possible with fejn's sustainable engagement rings, but only by one size up or down – for example, from 52 to 53. For rings with set diamonds, larger changes are not recommended to protect the setting.We recommend choosing a slightly larger ring size, as the wedding band or stacking ring worn later often complements the fit perfectly. If you would like a custom size, simply contact us at info@fejn.com

On which hand should an engagement ring be worn?

Traditionally in Germany, the engagement ring is worn on the left ring finger as a symbol of closeness to the heart. After the wedding, many couples switch the ring to the right hand or wear the wedding and engagement rings together – often the wedding ring on the right hand and the engagement ring on the left.Ultimately, however, your personal style is what counts: Wear your ring where it feels most beautiful and natural.

Where do the gemstones in fejn's sustainable engagement rings come from?

The gemstones in our sustainable engagement rings come from ethically vetted sources. We exclusively use lab-grown diamonds produced under controlled conditions – completely without mining, child labor, or environmental destruction.Other stones such as opals, emeralds or pearls also come from fair and responsibly managed supply chains – for genuine shine with a clear conscience.

Sustainable engagement rings

Sustainable engagement rings from fejn jewelry - timeless, minimalist and yet loving

Whether a sustainable engagement ring in gold, white gold, silver or rose gold - they all say one thing: It is the very great love! For many, the perfect proposal, the question of all questions, includes an engagement ring - and how nice when it really is a piece of jewelry forever. A thoroughly lasting gift for perhaps one of the most romantic moments of your relationship: that's what fejn jewelry has to offer! And of course our engagement rings are simple, timeless and sustainably produced - like all our jewelry.

Why sustainable engagement rings?

Not only the later wedding ring, but also an engagement ring woman now wears long-term. Whereas engagement rings were often discarded after the wedding in the past, engagement rings are now often optically linked with wedding rings - for example, as pre-stud rings. If you have worn your engagement ring on the left, it remains in place according to German custom. Or the ring moves from the right to the left hand after the marriage. In Germany, the wedding ring is usually worn on the right hand. In other countries it looks different. In Italy, for example, the wedding ring is worn on the left - close to the heart.

Especially if the engagement ring on the hand may and should remain forever, it is a pity if ethically dubious materials are used here. Especially materials like silver and gold are often mined under questionable working conditions. Not infrequently, even child labor is involved. And the environment also suffers from conventional precious metal mining. Massive amounts of CO2 are produced here. How good that fejn jewelry's sustainable engagement rings do without all these unsightly things. Our engagement rings are made from recycled precious metals. So in addition to their looks, they also shine because of their ethically sourced and produced nature. Want to know more around the use of recycled silver and gold? Then read our blog post on how to use sustainable materials.

By the way, engagement rings aren't just reserved for women. In the spirit of sustainability, more and more couples are opting for simple engagement rings together and then continuing to wear them as wedding rings after the wedding. This way, each of you wears a ring that stands for the whole story of your love.

Engagement Rings: Plain or with stone

If you like it straightforward, you will love the sustainable engagement rings, for example, made of gold, simple and without a stone. Who says that an engagement ring must always glitter? Exactly. A simple, timeless engagement ring says one thing above all: we belong together - and soon officially forever. You like simple rings, but you don't mind a little sparkle and shine in your engagement ring? Then fejn's sustainable engagement rings with diamonds are perfect. Good news: Diamonds can be sustainable too! If laboratory grown diamonds are used as they are at fejn, there is nothing standing in the way of an engagement ring not only with pure diamonds, but also with a clear conscience. All of our diamonds used are grown in certified laboratories. Best of all, they are indistinguishable from conventional diamonds in their chemical and physical properties.

Engagement rings gold or silver: the main thing is sustainable!

Today, virtually every brand is apparently sustainable. But behind the advertising promise is not always cash. At fejn jewelry it is - that's what we've been committed to since our founding.

Engagement rings: care for silver and gold properly

Lasting engagement rings want to be cared for. When you put away your new favorite ring that reminds you of your moment, please do so as airtight as possible. A small jewelry box or even a small cloth jewelry bag is suitable here. When showering, swimming in the pool or in the sea, you should take off your engagement ring. We also recommend protecting recycled precious metal engagement rings from perfumes, creams and cosmetics. These substances can attack the precious material and the shine will disappear.
