William Goldberg knew the secret to shaping a diamond’s fame and fortune. It takes passion, skill and considerable risk to create a famous diamond. And there’s one more thing: Legendary stones are christened with a moniker that defines their legacy and records their place in the annals of historic diamonds and gemstones. Just the mention of the Hope Diamond, for example, and people immediately know it’s the magnificent 45-carat blue diamond that resides at the Smithsonian in Washington DC.

That is why William Goldberg named another of the world’s most important blue diamonds the Blue Lili. It is named after his beloved wife, Lili, and to cement its place in the annals of remarkable diamonds. During his career, Goldberg held the naming rights to a number of incredible diamonds that he shaped into the famous diamonds – and that we still talk about today.

The Rock is William Goldberg’s latest record-breaking diamond making international headlines. At 228.31 carats (the size of an egg), it is the largest white diamond ever to come up for auction. On May 11, 2022, Christie’s sold The Rock for $21.9 million.
William Goldberg was a visionary who saw the possibilities in unusual rough diamonds – and he was willing to take the risk. A slight miscalculation when cutting and polishing the stone, and the diamond can crack or miss the mark of greatness.
“Diamonds in the rough have secrets, surprises and risks,” William Goldberg once said. “Intuition, experience, artistry and sometimes a bit of luck play a role in revealing what’s inside. But it starts with a decision, the courage to make an investment, and really the ability to see the light through the stone.”
His passion and expert eye were passed on to his son, Saul, daughter, Eve, son-in-law, Barry Berg, and grandson, Benjamin Goldberg, who continue to pursue and handle world-class diamonds.

The Blue Lili started as a 100 carat rough stone, but the legendary diamantaire sacrificed its size to carve the historic 30.06 carat diamond. The fancy intense blue diamond is revered for its deep blue hue, size and unique trapezoidal shape. And the name is just as memorable.
Yes, red diamonds exist, but you’ll probably never see one outside of a museum. So when William Goldberg heard about a 14-carat rough red diamond discovered in Brazil, he chased it down. After months of studying the stone, Goldberg decided to shape it into a modified triangular brilliant cut resembling a shield. The result: 5.11 carat fancy red, internally flawless diamond. The Red Shield was considered the largest red diamond at the time, and had the honor of being displayed twice at the Smithsonian Museum.
When William Goldberg saw the 40-carat imperfect pink rough diamond, he envisioned a record-breaking fancy colored diamond. After months of cutting and polishing, his master diamond cutters produced an 8.89 carat fancy vivid purple-pink oval diamond. It is ranked as one of the most beautiful pink diamonds of this size and color intensity.
You could say that William Goldberg became obsessed with the beautiful Ashoka diamond. Hundreds of years old, the original Ashoka was a 41.37 carat D flawless diamond in an elongated cut with rounded corners. After studying it intently for years, William Goldberg finally unveiled his own patented ASHOKA® diamond cut in the same elegant, flared shape with precisely rounded corners. It is the company’s proprietary cut, produced in limited quantities and in demand worldwide.
How To Make Synthetic Diamonds
When William Goldberg bought the 265.82-carat rough, its frosted exterior prevented him from making a detailed examination of what was inside. But Goldberg had an inkling that this was going to be something special. He was right: He fashioned it into four flawless D diamonds, including the spectacular 102-carat oval diamond, the size of an egg, and aptly named the Beluga.
At 137 carats, the magnificent Premier Rose is the sixth largest pear-shaped diamond in the world. More than its size, it is also an exceptional D internally flawless diamond. It began as a 353.9 carat rough stone discovered in the Premier Diamond Mine in South Africa. After hundreds of hours of cutting and polishing, William Goldberg created three extraordinary diamonds from the single rough stone. Fifty years after it was cut, the Premier Rose is still a famous diamond. Scientists are still figuring out how diamonds formed on Earth about one to three billion years ago. But while the research continues, if you wanted to try creating diamonds, maybe because you’re ready to take the next step in your relationship or you’re looking for an investment, here’s a rough recipe.
Next, make sure the carbon is heated to about 2,200 degrees Fahrenheit. It’s very hot that deep in the earth, so if you’re lucky, the conditions can be just right.
All the overlying rock creates the high pressure. Which is needed for this next step. You have to press the carbon under intense pressure: about 725,000 pounds per square inch. It is the temperature and pressure that binds the carbon atoms together in a unique arrangement; one carbon atom to four other carbon atoms. That’s what makes a diamond so hard.

Then send it rapidly upwards towards the earth’s surface to cool. Scientists say a deep-seated volcanic eruption is what brings diamonds to the surface. The diamond has to travel quickly to the surface to cool, (we’re talking hours) otherwise the resulting diamond would turn to graphite. When the diamonds are brought to the surface and cooled quickly, the carbon atoms are locked in place and there is not enough energy to turn them into graphite.
Scientists believe that the growth rates of diamonds depend a lot on the temperature and pressure, as well as on the presence of carbon, which is quite rare in the Earth’s mantle.
The time it takes to make a diamond should not be confused with the age of the diamond. Many diamonds that have been found are very old, dating back nearly three billion years. But scientists say it’s likely the rock was formed and then sat around, waiting to be discovered.
So good luck with your diamond work. And if the recipe doesn’t quite work, you can always opt for a diamond of the store-bought variety, for between an average of $3,000-$27,000 a pop (per carat). heat and earth pressure, natural diamonds were formed. So what makes one diamond different from another? What are the features that determine a diamond’s beauty and a diamond’s quality? Curious about cut, colour, clarity and carat? This blog aims to answer all your questions so that you can make an informed purchase. This is essentially what the 4 C’s of diamonds are.
What Makes A Diamond Sparkle?
Prices between different types of diamonds vary, and it is important that the buyer understands exactly what they are paying for. Ultimately, knowledgeable customers are happy customers. A higher quality diamond will cost more – quality is determined according to cut, colour, clarity and carat. It is an agreed standard in the industry.
The diamond cut is known to have the greatest impact on a diamond’s sparkle. The ideal cut is not too deep, nor too shallow, allowing the light to shine from the top of the diamond and not get lost in the bottom or sides. The ideal cut, which represents 3% of all diamonds, is the highest quality that reflects almost all incoming light, followed by very good, good and fair cuts.
The second most important factor affecting the appearance of a diamond, noticed immediately after the sparkle, is the color, or rather, the absence of color. A diamond is graded based on the lack of color, which marks its transparency. The color range (also called gradation) scales from the letters D to Z, as follows:
A reference to the imperfections, called inclusions, in the diamond that are usually only visible under a microscope. Although not readily visible, the inclusions still affect the way light is transmitted and reflected through the diamond body. The fewer and less visible the inclusions, the higher the grade of the diamond you buy. Therefore, you want to avoid visible inclusions. The scale (also called diamond clarity grade or diamond clarity chart) goes as follows:
What Makes Oval Cut Diamonds So Special?
Error-free and internally error-free. Even under 10x magnification, inclusions are not visible. Less than 1% of all diamonds formed are flawless and less than 3% have very small blemishes that are considered internally flawless.
Very, very little included. Inclusions are small and very difficult to see under a microscope even for a professional. VVS1 has very few inclusions while VVS2 has slightly more of them.
Very little included. This refers to smaller inclusions that are difficult to see (VS1) or easy to see (VS2) under a microscope.
A little included. Noticeable to the naked eye under close scrutiny. Inclusions in S1 diamonds are sometimes noticeable, while the inclusions of S2 diamonds are often noticed without magnification.
