Ditching the Ordinary! Choose an Engagement Ring That Highlights Your Unique Style with Colored Diamonds and Fancy Shapes

For that once-in-a-lifetime engagement ring, embrace a design and individuality that reflects both of you

With the prevailing budget for engagement rings ranging between 300,000 to 400,000 yen, making this purchase is truly a commitment for life. In recent times, some couples opt to forego buying engagement rings altogether.


Digging into the reasons reveals concerns about fashion taste alignment, lack of occasions to wear the ring, and financial constraints as the main deterrents, according to the Zexy Marriage Trend Survey 2022.


But what if you could create a ring that you both truly love and will cherish forever?


Celebrities abroad have set trends by choosing fancy-colored diamonds and unique diamond shapes for their engagement rings. This article aims to shake off traditional engagement ring stereotypes and help you find a truly personal symbol of your love.

Key Point #1: Diamond Shapes - Embracing Fancy Shapes

Are you familiar with the term "fancy shape"?


Fancy shapes refer to any diamond cut style other than the round brilliant cut, offering a variety of shapes that can completely transform the look of a ring.



Choosing a shape that matches your fashion sense and personality can highlight your uniqueness. Find the perfect shape that represents you.


1) Princess Cut Diamonds

A square or nearly square ratio makes the princess cut the second most popular diamond cut style today, next to the round brilliant cut. Each facet is elongated, which can give the sparkle a "mosaic pattern" when the light hits it.


The ratio is based on a perfect square (1:1), but since it's cut from mined rough stones, there's a slight individual difference in shape.


This cut's delicate sparkle and its straight, square composition offer a clean, streamlined effect on the hand.



2) Oval Cut Diamonds

The term "ovum," meaning "egg" in Latin, is the origin of the name for the oval cut. This shape is characterized by its elliptical form, offering a blend of a classical, mature appearance with a soft, rounded gentleness.


Setting the diamond lengthwise elongates the appearance of the finger, while a horizontal setting provides a rich sense of volume, enhancing the wearer's style.

3) Heart Cut Diamonds

The heart, a symbol of love and affection, is an ideal motif for bridal rings. Creating a heart shape requires removing more of the original stone during the polishing process, making it rarer compared to other cut styles.


Though it has a strong impression of cuteness, wearing it as one matures can show a playful spirit. It's a cut style that conveys a promise of love to the future.

4) Pear-Shaped Diamonds

The pear shape, also known as a teardrop, is characterized by its resemblance to a pear. It is designed from a combination of round and marquise cuts, which adds a sense of artistry.


Its voluptuous curves and sharp lines exude a graceful and delicate mood, and it has the effect of making fingers appear slender and longer.

5) Marquise Cut Diamonds

The marquise cut, reminiscent of leaves, rugby balls, or petals, features two curves that meet at a sharp point. This silhouette has the characteristic of making the surface of the stone appear larger than its actual carat weight, thus seeming more substantial.


Its refined atmosphere complements classic, antique, and simple designs well. The cool yet graceful impression is fitting for a piece of jewelry meant to last a lifetime.


6) Cushion Cut Diamonds

The cushion cut, also known as the antique cut or pillow cut, is characterized by its square shape with rounded corners, offering a gentle silhouette. Each facet is large, allowing for the enjoyment of the stone's clarity.


This cut style exudes a calm antique mood and is a timeless design often featured in Harry Winston's engagement ring collections. It combines softness with a neat impression, recommended for those who desire a hint of uniqueness without being too eccentric.


7) Emerald Cut Diamonds

The emerald cut is characterized by its octagonal shape with diagonally cut corners, made up of parallel facets known as a step cut. This arrangement results in a more subdued sparkle but enhances the stone's clarity.


This cut style is frequently used for emeralds and is recommended for those who prefer a more understated and elegant brilliance over a dazzling sparkle.


Let's review: What is the Round Brilliant Cut?

When viewed from above, it appears circular, and to maximize its brilliance, it is cut into 58 facets, including the culet.


This sparkling = diamond has defined the impression of diamonds, making it the most standard cut style.



Key Point #2 : Color Diamonds Expressing Individuality

Diamonds can acquire color either through specific substances contained within them or due to distortions in their crystal structure. While colorless diamonds are highly valued, colored diamonds with deep and vivid hues are also considered rare and often traded at high prices.


Natural or Tinted?

In addition to naturally colored diamonds formed in the environment, there are also artificially tinted diamonds. Although they may look similar externally, there's a significant difference in value and market price between them.

What are Fancy Color Diamonds?

In the diamond grading system, the 4Cs, any diamond whose color falls outside the D-Z range and exhibits deeper coloring is referred to as a fancy color diamond. Natural fancy colors are so rare that they often don't make it to the market but are instead auctioned off, with some famous examples like the "Hope Diamond" being stored in the Smithsonian Natural History Museum's Harry Winston Gallery.


Diamonds are miracles that have emerged from the earth over billions of years, and they boast beauty akin to art pieces, thanks to the craftsmanship of skilled artisans and designers.


Color Variations

Natural colored diamonds come in a variety of hues due to trace elements or structural distortions within the crystals. While the value assessment is important, each colored diamond is unique in its coloration, so choosing based on your personal taste and intuition can be a delightful experience.


1) Red Diamonds

One of the most rarely seen and highly rare colored diamonds. The exact cause of their striking red color is still a mystery, even with modern technology.


Compared to the red hue of rubies, red diamonds typically exhibit a pinkish-red color. In addition to pink, they can also have shades of orange, purple, and brown.

2) Green Diamonds

Green diamonds are also rare, believed to obtain their color from natural radiation exposure.


Typically, they have a bright color with low saturation, often appearing greyish or brownish, and those with vivid coloring are valued higher due to fewer inclusions.


3) Purple Diamonds

Purple diamonds are essentially pink diamonds that exhibit a bluer hue. Those with a deep, vivid coloration are highly rare and seldom seen in the general market.


If the stone appears purple but lacks sufficient blue, it's classified as a pink diamond. Conversely, if the color is too deep, it might be categorized as a brown diamond.

4) Orange Diamonds

Orange coloring arises from nitrogen presence.


Although rare and unfamiliar, orange diamonds become more accessible in price as they near a yellow hue.

5) Blue Diamonds

Blue diamonds are formed with the presence of boron, leading to captivating names such as Ocean Blue and Sky Blue diamonds.


According to the tradition of "Something Four," where a bride is said to gain happiness from wearing "Something Blue," embracing a blue diamond as a talisman of happiness can be a beautiful choice.

6) Pink Diamonds

Pink diamonds are highly sought after, with their prices on the rise. Discovered in 1979 at the Argyle mine in Australia, which was known for producing high-quality stones, the closure of this mine in 2020 without a replacement source has made these gems even more precious.


Their rarity combined with their charming color has made them beloved by many.

7) Yellow Diamonds

The yellow hue in diamonds comes from the presence of nitrogen, and compared to red, blue, or pink diamonds, yellow diamonds are more accessible.


For those familiar with diamonds, the distinction from the 4C's color grading might be intriguing. Yellow diamonds fall outside the D to Z color grading scale, indicating a deeper hue at that point, which classifies them as fancy.

8) Brown Diamonds

Brown diamonds, the oldest diamonds used in jewelry, were reportedly set in rings by the Romans in the 2nd century.


Primarily used for industrial purposes until the 1980s, the marketing of stones mined from the Argyle Mine as "Cognac Brown Diamonds" and "Champagne Brown Diamonds" has led to their widespread use in jewelry. There's a variety of shades available, ranging from those with reddish hues to those with gold and purple tints, offering a broad spectrum of options for selection.

9) Gray Diamonds

The gray coloration in diamonds can result from inclusions or hydrogen-related causes, though the specific mechanisms remain unclear.


These diamonds blend seamlessly with everyday wear and various settings, offering a cool and composed impression that transcends fashion or occasion.

10) Black Diamonds

Black diamonds exhibit a unique luster, distinct from onyx or tourmaline, offering stark contrasts when paired with clear diamonds for a gender-neutral appeal.
