At Pro Diamond Buyers we not only are the Sacramento area’s number one jewelry buyer, we are Sacramento’s number one diamond and jewelry educator. We take pride in helping our clients understand the world of Gemology and jewelry manufacturing. It is important to know what you are buying and especially what you are selling. Knowing what you have before you sell can bring very large rewards and piece of mind that you received the highest price. Some diamonds can be much more rare and valuable than others and knowing the facts is a must when making any purchase or sale of diamond jewelry. Below is a small sample of some exceptionally rare and famous diamonds that the Gemology world has cherished for many years.

The Millennium Star
The Millennium Star is a diamond owned by De Beers. At 203.04 carats, it is the world’s second largest known Top Color diamond (grade D, colourless), internally and externally flawless, pear-shaped diamond. This is perhaps one of our favorite fashioned diamonds. You can see this diamond’s images used throughout our ads and website art.

The Cullinan

The Cullinan Diamond was the largest gem-quality rough diamond ever found, weighing 3,106.75 carats, discovered at the premier no.2 mine in cullinan, south africa, on 26 january 1905. It was named after thomas cullinan, the mines chairman. In april 1905, it was put on sale in london, but despite considerable interest, it was still unsold after two years. In 1907, the transvaal colony government bought the cullinan and then presented it to edward vii, king of the united kingdom, who had it cut by asscher brothers in amsterdam.

Cullinan produced stones of various cuts and sizes, the largest of which is named cullinan i or the great star of africa, and at 530.4 carats it is the largest clear cut diamond in the world. The stone is mounted in the head of the sovereigns sceptre with cross. The second-largest is cullinan ii or the second star of africa, weighing 317.4 carats, mounted in the imperial state crown. Both are part of the crown jewels. Seven other major diamonds, weighing a total of 208.29 carats, are privately owned by elizabeth ii, who inherited them from her grandmother, queen mary, in 1953.

The Hope Diamond

The Hope Diamond is one of the most famous jewels in the world, with ownership records dating back almost four centuries. Its much-admired rare blue color is due to trace amounts of boron atoms. Weighing 45.52 carats, its exceptional size has revealed new findings about the formation of gemstones.

The jewel is believed to have originated in India, where the original (larger) stone was purchased in 1666 by French gem merchant Jean-Baptiste Tavernier as the Tavernier Blue. The Tavernier Blue was cut and yielded the French Blue (Le Bleu de France), which Tavernier sold to king Louis XIV in 1668. Stolen in 1791, it was recut, with the largest section acquiring its “Hope” name when it appeared in the catalogue of a gem collection owned by a London banking family called Hope in 1839. After going through numerous owners, it was sold to Washington socialite Evalyn Walsh Mclean, who was often seen wearing it. It was purchased in 1949 by New York gem merchant Harry Winston, who toured it for a number of years before giving it to the national museum of natural history of the united states in 1958, where it has since remained on permanent exhibition.

The Dresden Green

The Dresden Green Diamond, also known as “Dresden Green”, is a 41 carats natural green diamond, which probably originated in the Kollur mine in the state of Andhra Pradesh in India.

The Dresden Green is a rare Type IIa, with a clarity of VS1 and it is said to be potentially internally flawless, if slightly recut.

It is named after Dresden, the capital of the German state of Saxony, where it has been on display for most of the last two centuries, latterly in the New Green Vault at Dresden Castle. After World War II, it was relocated to Moscow for a decade before being returned to Dresden. In November 2019, it was sent on loan to the Metropolitan Museum of Art in New York City so was not involved in the jewel theft of 25 November.

The Dresden Green Diamond has a historical record dating back to 1722, when a London news-sheet carried an article about it in its 25 October-27th edition. It was acquired by Augustus III of Poland from a Dutch merchant in 1742 at the Leipzig Fair. In 1768, the diamond was incorporated into an extremely valuable hat ornament, surrounded by two large and 411 medium-sized and small diamonds. This is the setting that the Dresden Green still appears in today.

In 2000, American jewelry firm Harry Winston arranged to display the Dresden Green at the New York flagship store and then at the Smithsonian in Washington, DC, United States, where it was displayed in the Harry Winston pavilion next to the largest blue diamond in the world, the Hope Diamond.
