Unique necklaces with rare, big diamonds and colorful gemstones have been some of history’s most stunning jewellery. These rare jewels have sold for multi-million dollars at auction to collectors seeking the ultimate jewelry prize.

A Heritage in Bloom and the Queen Marie Antoinette Necklace are more than jewelry—they are stories of human creativity and beauty. This stunning tour will reveal the stories behind these gorgeous necklaces and their attraction, making them some of the most costly and cherished.

De Beers Diamond Necklace—$3.65M

A 1999 Sotheby’s auction sold this De Beers necklace with 478 diamonds, totaling almost 230 carats. The centerpiece is a rare 10.3-carat “Fancy Intense” yellow diamond.

Most jewelry diamonds are white or almost colorless, making brilliant yellow diamonds desirable. Prices are high for intense yellow diamonds, which make up less than 0.1% of world diamond output.

Auction prices for the necklace reached $3.65 million. Eva Peron owned it before other owners. De Beers and the yellow diamond spark intrigue.

Bulgari Two-Row Necklace—$3.7M

A stunning two-row bib necklace by Bulgari features 184 diamonds totalling 230 carats in swirling flower designs. The diamonds form an ombre neckline by alternating pink and white tones.

The necklace showcases Bulgari’s bright, vibrant patterns, which Hollywood stars love. Its stunning style and high-quality pink diamonds kept collectors interested.

Marie Antoinette Necklace—$3.7M

The Marie Antoinette is based on the last Queen of France’s magnificent necklace. Royal jewelers Charles Boehmer and Paul Bassenge made the 18th-century version.

In 1792, the French royal treasury was looted, and its 647 diamonds totaling over 2,800 carats vanished. Boucheron’s copy has 647 diamonds (978 carats) in a graded design that evokes French royal court luxury.

The 2018 auction brought $3.7 million for the necklace. Despite being a replica, its quality and connection to the last Queen of France made it worth millions.

Marie Antoinette’s habit of decorating noble necks continues over two centuries later.

Emerald-Diamond Necklace—$10.6M

This beautiful necklace with 50 Colombian emeralds weighing over 500 carats sold for $10.6 million. With diamond accents, the step-cut rectangular and octagonal stones form a lovely leaf-like pattern.

Famous for producing the best emeralds, the Muzo mine supplied them. They excel in color saturation, clarity, and cut.

The necklace’s subtle green fire separates it from historic items. Christie’s confirmed global demand for this exceptional Colombian emerald set.

Ruby-Diamond Necklace—$12.76M

This ruby and diamond necklace sold for $12.76 million at Christie’s in 2015 due to its high-quality centerpiece rubies. Pigeon blood red is one of their most prized colors—perfectly balanced.

Their cushion cuts enhance deep red saturation, and the basic ruby-diamond pattern contrasts elegantly with the flaming reds and frigid whites. The necklace recalls Art Deco, when nobles valued rubies globally.

Christie’s stated that quality and size rubies are becoming scarce, attracting top auction prices.
