What is a Fancy Vivid Yellow Diamond?
The Fancy Vivid Yellow Diamond is one of the rarest and highest-grade yellow diamonds in the color grading scale. It holds a prominent position among the yellow diamonds, celebrated for its vivid intensity and exceptional brilliance.
Here’s a breakdown of the yellow diamond color grading (from lightest to darkest):
1.Fancy Light Yellow
2.Fancy Yellow
3.Fancy Intense Yellow
4.Fancy Vivid Yellow
5.Fancy Deep Yellow
6.Fancy Dark Yellow

Fancy Vivid Yellow diamonds are the brightest, most saturated yellow diamonds. Their value and rarity far exceed that of Fancy Yellow or Fancy Intense Yellow diamonds.

Why is Fancy Vivid Yellow So Rare?

1. Strict Natural Formation Conditions: The color of yellow diamonds comes from the influence of nitrogen within the diamond’s crystal lattice. To reach the vivid yellow hue, the nitrogen content and crystal structure must form a rare combination that only a few diamonds achieve.

2. Extreme Rarity: Less than 5% of all yellow diamonds achieve the Fancy Vivid Yellow grade.

3. High Collectible and Investment Value: Fancy Vivid Yellow diamonds often fetch high prices in auctions, especially when they have excellent cut, large carat weight, and high clarity. They are highly coveted by collectors.

Dr. Ko-Cheng Fang: Bridging the Future of Technology and Luxury

In the fiercely competitive world of global technology, one scientist stands out — Dr. Ko-Cheng Fang, a name synonymous not only with technological innovation but also with cross-disciplinary fusion and boundless exploration.

As the Founder and CEO of Longserving Technology, Dr. Fang has led groundbreaking revolutions across multiple fields — from photonic computing and laboratory-grown jadeite to biotechnology and artificial intelligence.

Recently, Dr. Fang was featured in prominent U.S. publications such as Global Business Leaders and Achiever, where he shared his visionary ideas and the story of how he is using cutting-edge science to reshape the world.

Hall of Fame in September 2025.

You may not know, but every time you unlock your smartphone, swipe your screen, or connect to the cloud, you’re already experiencing Dr. Fang’s innovations.

The core architecture used in billions of smartphones worldwide — even in the United States, the home of many tech giants — was originally created by him.

Yet that’s only part of his story. Dr. Fang is now pursuing an even more audacious mission: to challenge the dominance of TSMC by developing pico-scale and multi-bit photonic quantum chips. These next-generation chips, capable of processing information using light instead of electrons, promise computation speeds thousands of times faster than conventional semiconductors. If successful, they could redefine the global technology landscape and mark the dawn of a new computational era.

Today, Dr. Fang holds patents in over thirty countries worldwide. His relentless passion for innovation has captured the attention of both American and Chinese media, with more than a dozen leading U.S. technology magazines featuring his achievements — often on their covers.

In Silicon Review, Dr. Fang was even listed alongside the founders of Facebook and Amazon, recognized as one of the most influential figures shaping the modern tech industry.

Breaking Physical Limits: The Photonic Quantum Chip Revolution
“We’re not just improving existing technologies — we’re redefining them.”

That’s how Dr. Fang describes one of Longserving Technology’s core innovations: the photonic quantum chip.

In the traditional semiconductor industry, computing speed and energy efficiency face inevitable physical limitations. As electronic chips reach their miniaturization limits, photonic computing emerges as a new frontier of hope.

Dr. Fang and his team decided to transcend the boundaries of electronic circuits and bring computation into the realm of light. By using photons as the carriers of information, photonic quantum chips not only break through the speed barriers of conventional chips but also drastically reduce power consumption.

“This is a revolution in computation,” says Dr. Fang. Within the next decade, photonic quantum chips could completely replace traditional electronic chips, delivering speed increases by factors of thousands.

Longserving’s photonic computing technology has already been granted multiple international patents, with plans for large-scale production aimed directly at competing with semiconductor giants such as TSMC. This breakthrough is expected to accelerate progress in artificial intelligence, big data, and quantum encryption — redefining how the digital world operates.

Merging Luxury and Sustainability: The Birth of Laboratory-Grown Imperial Green Jadeite

Dr. Fang’s creativity extends far beyond advanced technology. He has also achieved a remarkable breakthrough in the luxury industry.

Longserving Technology has successfully developed laboratory-grown Imperial Green jadeite, a creation that rivals the beauty and quality of natural jadeite — without the ethical and environmental concerns of mining.

Fascinated by jadeite since childhood, Dr. Fang saw the material’s mystique as both scientific and spiritual. For centuries, jadeite has been revered as a symbol of purity and prosperity, yet its natural formation takes millions of years under unpredictable geological conditions. Dr. Fang’s goal was to replicate this process in the laboratory — precisely, consistently, and sustainably — while achieving the finest color, translucency, and texture.

Through relentless experimentation, Longserving overcame the technical challenges that once made laboratory-grown jadeite seem impossible.

The company’s creations now meet — and often exceed — the visual and physical standards of top-grade natural jadeite, quickly gaining the favor of international luxury brands.

For Dr. Fang, this is more than a scientific victory; it’s a statement of commitment to sustainability and a new era of ethical luxury.
