1. What is Carat? What Does it Mean and What Does it Do in Engagement Rings?
1.1 Basic knowledge of carats
Carat is a unit of weight for gemstones , with 1 carat equaling 0.2 grams . This unit originated in ancient times when carob seeds were used as a weight standard. Today, it is standardized internationally and is widely used to evaluate gemstones, including diamonds. The higher the carat number, the heavier the diamond and generally the larger its size.

1.2 Relationship between diamond appearance and carat weight
As carat weight increases, so does the diameter of a diamond, but the change is not as dramatic as the weight. For example, a 0.5 carat (approximately 5.2mm diameter) diamond is twice as heavy as a 1 carat (approximately 6.5mm diameter) diamond, but its diameter is about 1.3 times larger . This may not seem like a big difference visually .
1.3 Trends in carat size chosen for engagement rings
The carat size of diamonds chosen for engagement rings varies depending on the region and culture.
- Japan : 0.3 to 0.5 carats are the norm. Simple and understated designs are popular.
- America and Europe : Diamonds of 1 carat or more tend to be preferred. This is likely due to the strong influence of cultures that place importance on a gorgeous appearance.
However, in recent years, due to the influence of social media and other factors, engagement rings with larger diamonds and more glamorous designs have become popular in Japan. More and more people are looking to express their individuality and a sense of specialness with their engagement rings.
2. Size and Price: Why Carat Weight Isn't the Only Thing
2.1 Diamond Price Structure
The price of a diamond does not simply increase in proportion to the carat size . For example, if a 1-carat diamond costs 500,000 yen, a 2-carat diamond will typically cost over 1.5 million yen, rather than twice that amount. This is because larger diamonds are rarer.

- 0.5 carat diamond: Over 300,000 yen
- 1 carat diamond: over 1 million yen
- 2-carat diamond: over 3 million yen
2.2 The impact of the "4Cs" on prices
The price of a diamond is not determined solely by its carat weight. It is influenced by a comprehensive set of criteria known as the " 4Cs ":
- Cut : A processing technique that maximizes the brilliance of a diamond
- Color : Transparency and color grade
- Clarity : The presence or absence of inclusions or surface scratches
- Carat : Weight
In particular, a diamond with a good cut is often given more importance than other factors and has a significant impact on the price.
3. Tips for choosing the perfect engagement ring carat size
3.1 Research your partner's preferences
It is important to find out in advance what design and size the person you are giving the engagement ring to prefer. You can get some hints by observing the size and style of their everyday jewelry.
3.2 Set a clear budget
To make the best choice within your budget, you need to consider not only the carat weight but also the balance of factors such as color and clarity. For example, even if the carat weight is slightly smaller, if the cut is excellent, the sparkle will be beautiful and you will be more satisfied.
It is also effective to choose a shape that will make the diamond appear larger visually relative to its carat weight (such as an oval, pear, or emerald shape ).
3.3 Consult a trusted jeweler
By consulting with a jeweler with specialized knowledge , you can find the diamond that best suits your needs. You can also rest assured that you will receive a transparent explanation of the diamond's quality and price. Instead of focusing solely on the carat weight, consider the balance of the 4Cs to choose the best diamond within your budget.
3.4 A special carat size that symbolizes eternal value
Round carat sizes like 1 carat or 1.5 carats can have special meaning in engagement rings, and choosing these carat sizes can add a touching story.
3.5 Choosing a Lab-Grown Diamond
Large carat natural diamonds are very attractive, but they also come with a higher budget. By comparing natural diamonds with lab-grown diamonds, you can get an ethical engagement ring that will satisfy you .
