These are perfectly valid questions, because the ring is not only a symbol of your love but also an investment. But don’t worry—we’re here to help you sort through the options and find the ring that’s perfect for both of you.

How Much Does an Engagement Ring Cost? The 2026 Price Guide
There’s no one-size-fits-all answer to the question of how much an engagement ring costs, as the price depends on many factors. Nevertheless, there are clear trends and average figures that can serve as a guide. According to the Bridebook Weddings Report 2026, the average price of an engagement ring in Germany is about 1,125 euros [1].
The old rule about how much an engagement ring should cost —namely, three months’ salary—is long outdated and stems from a marketing campaign in the 1930s. Today, what matters most is your individual budget and the meaning the ring holds for the two of you. A ring that costs 400 euros can be just as meaningful as one that costs several thousand euros, as long as it comes from the heart and suits the two of you.
Factors That Affect Price
The price of an engagement ring is determined by several key factors:
- The diamond (or gemstone): This is often the biggest cost factor. Its quality is determined by the 4 Cs: carat (weight), cut, clarity, and colour.
- The material: gold (585 or 750), platinum, or silver. Platinum is the most expensive, gold is the standard, and silver is the least expensive.
- Craftsmanship & Design: Elaborate designs, custom-made pieces, or special settings increase the price.
- Brands vs. Artisans: Well-known brands often charge higher prices than local goldsmiths for comparable quality.
- Origin & Sustainability: Recycled gold or lab-grown diamonds can affect the price, but they also offer ethical benefits.
Diamond Carats: What Do They Really Mean?
When it comes to diamonds, the word “carat” is everywhere. But what does “carat” really mean when it comes to diamonds? A carat (abbreviated as ct) is the standard unit of weight for diamonds and other gemstones. One carat is exactly 0.2 grams. It’s important to understand that a carat indicates the weight—not the size—of a diamond. A diamond carat is therefore a unit of measurement for weight.
A diamond's apparent size is not determined solely by its carat weight, but largely by its cut. A well-cut diamond can appear larger than a poorly cut one, even at the same carat weight. Here is a diamond carat chart for round brilliant-cut diamonds that converts carat weight to millimeters:
| Carat Weight (ct) | Diameter (mm) |
|---|---|
| 0.25 ct | approx. 4.1 mm |
| 0.50 ct | approx. 5.1 mm |
| 0.75 ct | approx. 5.8 mm |
| 1.00 ct | approx. 6.4 mm |
| 1.25 ct | approx. 6.9 mm |
| 1.50 ct | approx. 7.4 mm |
| 2.00 ct | approx. 8.2 mm |

How many carats should an engagement ring have?
The question of how many carats an engagement ring should have is a very personal one. There is no set rule, as it depends on individual preferences, budget, and desired style. In Germany , diamonds ranging from 0.25 to 0.5 carats are very popular for engagement rings and are considered a classic choice.
Thanks to modern technologies such as lab-grown diamonds, it’s now easier than ever to find a stunning stone without breaking the bank. These diamonds are chemically, physically, and optically identical to mined diamonds, but significantly more affordable. That means you can choose a larger stone—that is, a diamond with a higher carat weight—than would be possible with a traditional diamond.
At Velur, you'll find an exquisite selection of engagement rings featuring lab-grown diamonds and moissanites that combine maximum brilliance with ethical responsibility. This allows you to choose the carat weight of your engagement ring without having to compromise on quality or budget.

3 Golden Rules for Buying an Engagement Ring
Buying an engagement ring is a matter close to the heart. Keep these three golden rules in mind to make the best decision:
"The value of an engagement ring isn't measured in euros or carats, but in the love and meaning it symbolizes. Choose with your heart, but also with your head."

- Set a realistic budget: Think ahead of time about how much an engagement ring should cost to you personally. Don't let social expectations put pressure on you. A well-thought-out budget will allow you to relax and find the perfect ring.
- Understand the 4 Cs: Carat, cut, clarity, and colour are particularly important when it comes to diamonds. Educate yourself so you can accurately assess the quality and value of the stone. A well-balanced cut can make a smaller-carat diamond appear larger.
- Consider your partner's style: Pay attention to the jewellery she already wears. Is it more delicate or eye-catching? Does she prefer gold, white gold, or platinum? These details will help you choose a ring that suits her taste and that she'll enjoy wearing.
Frequently Asked Questions (FAQ)
According to recent studies, the average price of an engagement ring in Germany is about 1,125 euros. However, the price range is wide, varying from a few hundred to several thousand euros, depending on the material, diamond quality, and design.
The old rule of thumb about "three months' salary" is outdated. How much an engagement ring should cost depends on your individual budget and the significance you attach to the ring. More important than the price is that the ring suits you as a couple and that you feel comfortable with it financially.
A carat is the unit of weight for diamonds and gemstones. One carat is exactly 0.2 grams. It is important to understand that a carat indicates the weight of a diamond, not its size. Two diamonds with the same carat weight may appear to be different sizes depending on their cut.
The ideal carat weight depends on personal taste, budget, and the desired look. In Germany, diamonds between 0.25 and 0.5 carats are very popular for engagement rings. Thanks to lab-grown diamonds, larger stones of 1 carat or more have become more affordable even for those on a tighter budget.
The price of a diamond is determined by the 4 Cs: carat weight, cut, clarity, and colour. A higher rating in any of these criteria significantly increases the price. The type of diamond (mined diamond vs. lab-grown diamond) also plays a major role.
Not necessarily. A higher carat weight simply means a greater weight. A diamond with a lower carat weight but an excellent cut, high clarity, and good colour can be more visually impressive and valuable than a larger diamond of inferior quality in the other 3 Cs. It all comes down to balance.
Natural diamonds form underground, while lab-grown diamonds are created in controlled laboratory environments. They are chemically, physically, and optically identical. However, lab-grown diamonds are generally much more affordable and ethically sound, allowing you to purchase larger carat weights for the same budget.
