Your engagement ring guide: Sustainable engagement rings from fejn Jewelry

Why elegant engagement rings?

With a fair and ecological engagement ring from fejn jewelry, your 'yes' will be timeless and even more sustainable - in two senses. Your ring is unique because it is only made to order and individually for you. We think: Your love is unique and should last forever - just like the engagement ring. But how do I find a suitable engagement ring for my great love and what should I consider? We will help you in our step-by-step guide:

Step 1: Choosing the precious metal

First, you should choose a precious metal. At fejn, you can choose between recycled 14k yellow gold, white gold or rose gold for all engagement rings. It's best to observe your true love a little: what color do the pieces of jewelry she wears? Perhaps you already know what color the wedding rings should be? Use this as a guide when making your selection.

Step 2: Choosing the diamond

The cut, shape and colour of the diamonds determine the style of your ring. Would you like it to be a timeless classic, like our 'the classic engagement ring', or should the ring have symbolism, like the 'the trio engagement ring', whose three stones represent the past, present and future and thus your shared history? Would your loved one like to wear the engagement ring as a classic stacking ring to the wedding rings? Then the 'memory diamond ring' is also a great choice, with its continuous diamonds symbolising eternity and going perfectly with any wedding ring.

If you are looking for something unique, then 'the modern engagement ring' or 'the iconic engagement ring' are the right choice for you. Their composition of diamonds is very special and a real eye-catcher.

Your love couldn't be greater and you want to show it? Then you can choose 'the eternal engagement ring', whose 0.5 carat diamond is not only something very special because of its size and brilliance, but whose diamond setting is also wonderfully dreamy.

Find out your ring size

This is probably the most difficult part: what ring size should you choose when ordering? Of course, the engagement ring you choose should also fit for the most romantic moment of the question. Here and here on our blog you will find various ways to determine your love's ring size. You can also download a size guide here, which you can use to easily determine the perfect ring size based on rings you already have.
If the ring doesn't fit, it is possible to adjust it in most cases. But be careful - this does not apply to all models. You can find this information on the individual pages for the engagement rings.

The big moment

After 4 to 6 weeks of production time, your ring is ready and nothing stands in your way. We will send you the ring in a high-quality and environmentally friendly case, perfect for the perfect proposal!

Of course, you have to plan everything around it, but we are sure that you already have the perfect idea that suits you on how to make this proposal unforgettable!
