Exclusive engagement rings: precious in several ways
Exclusive engagement rings are often worn after the wedding as an absolute eye-catcher. Just the unforgettable moments associated with different experiences in your life, such as the marriage proposal, the wedding and the honeymoon, make our exclusive engagement rings into jewels full of emotions. The memoir ring, a popular engagement ring, is unparalleled not only for its multitude of diamonds, but also for the high intangible value of special memories.

A precious platinum engagement ring in combination with a flawless diamond or a ring full of emotions and special memories – the exclusivity of an engagement ring knows no limit.

The price of an engagement ring
How much an engagement ring costs depends on the style of your fiancé-to-be. Some people believe that an engagement ring should cost two or three months’ wages, but that is a typical American custom on the one hand and the result of clever marketing tactics on the other. In other words: you determine the ideal price for an engagement ring yourself! In our versatile range you are sure to find an engagement ring that suits your budget and specific preferences.

Engagement ring with diamond
Why is it that one diamond engagement ring is more expensive than another? This has everything to do with the quality of the diamond and therefore also its brilliance.

All this is mainly determined by the most important criteria, the so-called four Cs of the stone: cut (cut), clarity (brightness), color (colour) and carat (carat or size). So don’t be fooled by the size of a diamond, but also see how the stone scores in the three other areas.

Choose from our many different ring models and choose the setting and shape of the diamonds yourself: brilliant, princess or baguette or a romantic heart shape.

Which hand to wear an engagement ring on?
There is no one-size-fits-all answer to the question on which hand you wear an engagement ring. Some people wear both their wedding and engagement rings on the left hand, others on the right hand or even on a necklace. In fact, it just depends on your personal preferences as a bridal couple, although you can perhaps take into account that if you are right-handed, the ring will remain beautiful longer if you wear it on your left hand.

Where to buy an engagement ring?

The impact of the Ring Profile and Ring Width

Engagement rings come in many rings and in different widths. The profile shape and width have a major influence on the size of the ring. Time to highlight this as well in this Engagement Ring Size Chart.

Rings that have a convex profile on the inside slide much easier on the finger than rings that are straight on the inside.

Below is a chart that shows common ring widths in millimeters converted to inches.
If you have a ruler close to you, it is easy to visualize how wide the ring you are about to order will be. Width in rings does matter for comfort and wearing of the ring: Narrow rings are easier to put on and take off than wide rings.

How do I measure the engagement ring size I need?

You have found the woman or man you want to spend the rest of your life with, you might have already found the engagement ring of your dreams? Let’s see how you can easily measure the engagement ring size discretely or in secret.
How do you know if the ring fits properly? In the below “how to measure your ring?” section you will find some easy ways how to determine your engagement ring size.

Below you will find three common ways to measure your ring size right at home.
Ring sizes are displayed in different ways. In the above ring size charts we have added both Inner Diameter as Ring Circumference in millimeters and inches which you can convert to the size. Other brands choose to use the inner circumference as the size. Sometimes the American ring size is also used. It’s not difficult in itself, but a bit confusing every now and then. We almost always use the inner diameter, because it is the easiest to determine yourself.

Time needed: 2 minutes.

Determining your ring size can be done in a number of easy ways. Let’s look into some ways

  1. Ring size and temperature: Take ring measurement of your fingers on different times of the day

    If you are going to measure your ring size, you have to take into account one important detail: your fingers expand with heat.
    This can happen on hot days in the summer, but also in a warm room.
    It is advisable to measure your ring size at different times of the day. For example, do this in the morning, afternoon, and evening. Then take the average of all measurement moments to find the ideal size for your Cartier ring.

  2. Measure the diameter with a ring

    The easiest way to determine a ring size is on the basis of a ring that fits you well and is comfortable. This way is also useful if, for example, you want to surprise someone with a ring and you do not want to ask them about their size. You can then easily ‘borrow’ a ring to measure.
    Measure ring size with a ruler
    Take the matching ring and place it centered on the measurement units of a ruler. Place the inside of the ring at 0 cm and read the number of millimeters on the other inside. This is the inner diameter ring size. We use the diameter ring size the most. You can look up in the table which circumference ring size belongs to that.

  3. Measure the circumference without the ring

    If a suitable ring is not available, it is best to estimate the diameter of the ring by using a ribbon or string.
    Measure ring size with a ribbon or string
    Loosely wrap the ribbon or string around the finger on which the ring will be worn and cut it where the ribbon meets. Measure the piece that remains with a ruler in millimeters. The length of the ribbon is the circumference of your finger and therefore the circumference ring size you need. You can easily look up the diameter ring size in the table above.
    Measure the ring size with paper, scissors and pencil
    You can also cut a strip of paper to wrap around your finger for this method. You can then simply mark the size with a pencil or pen. Measure the length along a ruler. You measure the circumference ring size that you need.
    Measure the ring size with a paper strip and pencil

  4. Use a tape measure

    This is not a very accurate method, but it is easy and fast. The advantage is that a measuring tape is nice and wide, so you measure over a somewhat larger part of the finger. Proceed as follows: Wrap the measuring tape around the finger and read the number of millimeters where the tape meets again. The length you now have is the inner circumference of the ring. You now know the circumference ring size of the finger. You can look up the diameter of the ring size in the table above.

  5. Consider your knuckle Size.

    when you have large knuckles, you should order half a size bigger than what your finger ring size measurement alone shows, otherwise it will be very unlikely you can slide your ring into the right place.

  6. Use a Caliper of go to a jeweler
