History of Diamonds
As a specialized jewelry store, agete values not only design but also the quality of gemstones. When selecting diamonds, there are standards of quality known as the "4Cs." These are the four elements: Cut, Carat, Color, and Clarity. By understanding these, you can choose diamonds that truly satisfy you.
At agete, we place the greatest importance on "Cut." The brilliance of a diamond is determined by its cut. We primarily handle "Triple Excellent" and "Excellent" cuts, which have been evaluated based on international standards. Additionally, the cut design also significantly affects the impression of the stone. Please take your time to consider the combination of design and size that suits you best.
When purchasing jewelry, it's also important to check where the diamonds were mined. We will continue to carefully confirm the production areas of the diamonds we handle and strive to provide safe and secure jewelry.
Quality
There are standards of quality for diamonds, known as the "4Cs." These are the four elements: Cut, Carat, Color, and Clarity. At agete, we source diamonds from suppliers who strictly adhere to international standards, carefully verifying quality.
1. Cut
"Cut" refers to the skill of cutting a diamond. Among the 4Cs, it's the only evaluation that depends on human craftsmanship. The brilliance of a diamond is greatly influenced by its cut. We mainly handle "Triple Excellent" and "Excellent" cuts, which are evaluated based on international standards.
Round brilliant cut
A traditional cut with 58 facets, designed to maximize light reflection. It brings out the brilliance of diamonds most effectively. This cut is the most evaluated and popular worldwide.
Rose cut
A traditional European cut with a dome shape and triangular facets, resembling the petals of a rose when viewed from above. While it produces less brilliance compared to brilliant cuts, it has an antique charm and soft sparkle.
Baguette cut
A simple rectangular or square step-cut design. The name comes from the French word for "stick" or "rod," referencing its elongated shape.
Princess cut
A modern brilliant cut with a square or rectangular outline, featuring numerous facets that create exceptional brilliance rivaling round brilliants.
Trillion cut
A brilliant cut in a triangular shape. It's characterized by a large table, producing strong brilliance.
Pear shape
A teardrop-shaped cut, also called "drop-shaped" or "teardrop." It elegantly extends the fingers when worn as a ring.
Marquise shape
An elongated oval shape with pointed ends on both sides. The name comes from the Marquise de Pompadour. The sharp outline creates an elegant impression.
Heart shape
A heart-shaped cut. It's a popular design symbolizing love, especially for gifts.
2. Carat
"Carat (ct)" is the unit for the weight of diamonds and colored gemstones. 1 carat equals 0.2 grams (200 milligrams). While carat indicates weight rather than size, stones with the same carat weight may appear different in size depending on their cut and shape. Generally, larger stones (higher carat weight) are rarer and more valuable, but diamonds are comprehensively evaluated by all 4Cs, not just carat weight. Additionally, if the carat weight is the same, differences in cut quality can significantly affect brilliance and beauty.
For rings, 0.18-0.25ct stones can be worn daily, while 0.3ct and above create a gorgeous impression. For necklaces, 0.1-0.18ct offers an elegant balance that complements necklines beautifully. At agete, many designs incorporate smaller diamonds, so please consider the overall balance with the design when choosing.
3. Color
Diamonds are graded for color on a scale from D to Z. Colorless stones are the most valuable, and as they take on a yellowish tint, their value generally decreases.
The color grading of diamonds ranges from D (colorless) to Z (light yellow). D, E, and F grades are called "colorless," showing almost no color. G, H, I, and J are "near colorless," appearing nearly colorless to the untrained eye. K, L, and M are "faint yellow," where color becomes slightly more noticeable. N to Z grades show increasingly visible yellow tones.
When choosing a color grade, it's important to consider the balance with the metal and design. At agete, we recommend near colorless G to J grades, which offer good value while maintaining beauty. K and L grades can also provide a unique warmth and soft impression.
4. Clarity
"Clarity" is the evaluation standard for a diamond's transparency. The degree of transparency is graded by examining inclusions (internal characteristics) and blemishes (surface characteristics) formed during the diamond's creation process under 10x magnification. Diamonds with fewer inclusions have higher transparency and exhibit beautiful light reflections. The clarity grade is classified into 11 levels. Generally, higher grades (fewer inclusions and blemishes) are considered more valuable, but VS2 and above are difficult to distinguish with the naked eye, making them a good value option. At agete, we primarily handle VS and SI grades. Please choose according to your budget and preferences.

Diamonds are formed over billions of years deep within the Earth and brought to the surface by volcanic activity. Ancient people who discovered them used these beautiful stones as talismans and decorations.
In the Middle Ages, diamonds were so hard that cutting technology hadn't developed, so they were used in their natural octahedral form. It wasn't until the late Middle Ages that polishing techniques emerged. In the 17th century, the "rose cut" became popular, and in the 20th century, the "brilliant cut" - which maximizes a diamond's brilliance - was invented. This is the most common form today.
The history of diamond mining and trading is also connected to human history. The earliest diamond mines are said to have been in India, and from ancient times, diamonds were traded along the Silk Road to Europe. Later, diamonds were discovered in Brazil and South Africa, making them available worldwide. Today, diamonds are mined in many countries including Russia, Botswana, and Canada, but ethical issues around mining and trading require careful attention.
World
Famous diamonds have always existed throughout human history. Legendary diamonds such as the Hope Diamond, Regent Diamond, and Star of Africa have witnessed the rise and fall of empires, unfolding love stories, and the evolution of cultures. Each stone carries centuries of human experience. These famous diamonds are not just valuable as gemstones, but also as symbols witnessing the glorious history of humanity.
1. Hope Diamond - Legendary Blue Diamond (America)
This deep blue diamond weighing about 45.52 carats has passed through the hands of French kings and American millionaires. Its mysterious color comes from trace amounts of boron. Known for its association with various legends and curses, it's now housed in the Smithsonian Museum of Natural History in Washington, D.C. The Hope Diamond is one of the world's most famous diamonds, having experienced a dramatic history and survived to the present day. Its deep blue color captivates all who see it. Legend has it that it was originally mined in India, passed through France's Louis XIV and Marie Antoinette, eventually reaching jeweler Henry Philip Hope in England (hence its name), and later acquired by American gem collector Evalyn Walsh McLean. It's also famous for the "curse legend" - said to bring misfortune to its owners. However, such legends were likely exaggerated as part of its mystique, and its true value lies in its rare beauty and historical significance.
2. Regent Diamond - Jewel of the French Royal Family (France)
This large diamond weighing about 140.64 carats is famous for adorning the French crown. Discovered in India in 1698, it was purchased by the Regent of Orleans, Philippe II. It later decorated Napoleon Bonaparte's sword and was used in the coronation crowns of successive French kings. Today it's displayed at the Louvre Museum in Paris. The Regent Diamond captivates many with its size and beautiful cushion cut. Particularly during Napoleon's reign, its use as a sword decoration symbolized his authority and power. In later years, it was set in crowns and tiaras used by French queens and empresses. This diamond is not just valuable as a gemstone, but also as a symbol witnessing France's glorious history.
3. Star of Africa - World's Largest Cut Diamond (South Africa)
This pear-shaped diamond weighing about 530.2 carats is the largest colorless cut diamond in the world. It was cut from the 3,106-carat rough diamond "Cullinan" discovered in South Africa in 1905. The largest stone from this cutting became the "Great Star of Africa (Cullinan I)" and is set in the British royal scepter. This cut showcases the cutter's exceptional skill, and its overwhelming size and brilliance attract many people. The Cullinan rough diamond was cut into multiple stones, each becoming part of the British Crown Jewels. The Star of Africa is displayed in the Tower of London, symbolizing the history and authority of the British royal family. The discovery of this diamond also greatly influenced South Africa's diamond mining industry, leaving a significant mark on the region's economy and history. The Cullinan Diamond remains legendary as the world's largest gem-quality rough diamond ever found.

Diamonds are not just formed within the Earth - they are born from romance.
As symbols of eternal love, they have been used in engagement and wedding rings since ancient times. Their hardness symbolizes an unbreakable bond, and their brilliance represents the brightness of the future for two people.
Particularly since Archduke Maximilian of Austria gave a diamond ring to Mary of Burgundy in the 15th century, diamond engagement rings have spread among European nobility. This tradition continues today, and diamond rings have become essential items symbolizing marriage worldwide.
