1. What is an Oval Cut?

An "oval cut" features an oval-shaped diamond, which is a slightly elongated version of the round cut. The oval shape visually elongates the finger and reflects light in multiple directions. This refined cut gives off a brilliant sparkle and can make you appear more feminine and elegant.

 

 

Furthermore, the oval shape of the oval cut has the effect of appearing visually larger, making it look bigger than a round cut of the same carat weight. Unlike other common cuts, this cut is distinctive and easily matches various styles.

 

 

Moreover, the oval cut is said to be one of the most effective ways to make a diamond sparkle. It has 58 facets and a basic structure similar to the common "brilliant cut." Therefore, the oval cut is excellent at enhancing a diamond's brilliance, making it a suitable diamond cut for engagement rings that accentuate femininity.

 

 

 

 

2. The Meaning of Giving an Engagement Ring

Engagement rings, also known as "engagement rings," carry special significance.

 

 

An engagement ring is a ring "given by a man to a woman as a promise of marriage," and it is worn during the engagement period and on special occasions. By giving it from a man to a woman, it visually demonstrates love and a strong commitment to marriage, and also serves to publicly announce the engagement to others.

 

 

Diamonds are primarily used for engagement rings because their hardness symbolizes "eternal love and bond." Designs featuring a diamond as the main stone, accentuated by platinum and gold, are very popular.

 

 

 

 

3. Benefits of Choosing an Oval Cut for an Engagement Ring

The benefits of choosing this oval cut from among many other cuts are as follows:

 

 

 

① Feminine Elegance

The oval cut, radiating light, exudes an elegant charm with its strong brilliance. Like an actress in a classic movie, it will subtly enhance your journey into a new stage of life and your daily existence with luxurious allure.

 

 

 

② Unleashed Individuality

With a shape different from other engagement rings, it is also ideal for unique styles. The presence of a large ring on your finger strengthens the wearer's identity, illuminating you from your hand during any special milestone.

 

 

 

③ Practicality that matches any style

Despite its individuality, the oval cut functions as a fashionable accessory. Since it's a ring you'll wear for a lifetime, you want a design that seamlessly fits into your daily life. Choosing a design that can be used not only on special anniversaries but also for everyday wear and cherished long-term might be an important option for an engagement ring.

 

 

 

It is also recommended to wear it with a simple ring. In this way, while being a precious ring for special occasions, the oval cut is also a very optimal choice for an engagement ring that can enhance both individuality and femininity in any style and be used for a long time.

 

 

 

 

4. 3 Important Points to Consider When Choosing an Oval Cut

① Length-to-Width Ratio

Oval cut diamonds vary in their length-to-width ratio. A different balance can significantly change the impression when worn. Since oval cuts do not receive cut grades like regular round cuts, there are differences in length-to-width ratios, and you must decide the shape of the stone yourself.

- Longer horizontally

In this case, the length-to-width ratio approaches 1:1, resembling a typical round cut. While the diamond itself is sufficiently clean and beautiful, the gradation of the length-to-width ratio becomes smaller, which reduces its unique impression.

- Standard length-to-width ratio

This shape is generally considered beautiful. It is the most well-proportioned form, with good balance that brings out the unique character of the oval cut. When worn, it makes the finger appear more slender and gives a feminine and elegant impression.

- Longer vertically

This shape is more vertically elongated than the ratio generally considered beautiful. The more vertical the ratio of an oval cut, the stronger the diamond's individuality, giving a vertically elongated oval cut a stronger elegant impression.

 

 

 

 

② Bowtie Effect

Oval cut diamonds require attention to the "bowtie effect." The bowtie effect refers to the phenomenon where a dark area appears to cross the center of an oval cut, resembling a bowtie-shaped shadow in certain diamond cuts.

Due to its cutting structure, it is impossible to completely avoid the bowtie effect (a bowtie-like shadow) in oval cut diamonds. Although this phenomenon is less noticeable in other cuts, it tends to appear more frequently in elongated shapes such as marquise and pear cuts.

 

 

If you are concerned about it, it is recommended to choose a stone where the shadow appearing in the center is not too dark.
By choosing an oval cut with a moderate contrast, you can enjoy a more beautiful sparkle and a well-balanced impression.

 

 

On the other hand, for stones with excellent cut quality, the bowtie effect can be mitigated by light reflection. Therefore, when choosing an oval cut, we recommend examining the actual stone to confirm the appearance and intensity of the bowtie before purchasing.

 

 

Furthermore, we offer bowtie-free oval cuts (Crushed Ice Cut). We also provide an optional service where you can choose your diamond yourself. If you are looking for your ideal sparkle, please feel free to consult us.

 

 

 

 

③ 4Cs

The 4Cs refer to "Cut," "Carat," "Clarity," and "Color." Carat, in particular, signifies the "weight" of a diamond, with 1 carat equaling 0.2g. The other three Cs are graded in stages, and the overall evaluation determines the diamond's price, but a larger carat weight tends to have a greater impact on the price.

For example, for typical 2ct or 3ct diamonds, even a single grade difference can lead to price fluctuations of hundreds of thousands of yen, but with our lab-grown diamonds, large diamonds of 1.5~2ct or more are available starting from an additional 10,000 yen for a grade upgrade.
