As August draws to a close, let's have an up-close and personal look at the gemstones from one of the world's most magnificent suites of peridot jewels: the Habsburg Peridots. For the tumultuous ownership history of the set, read our earlier article over here. The super-close images below of the necklace and earrings are from the set's 2004 outing at the Golden Globes.

Tiara Timeline: Queen Victoria's Sapphire Coronet

With this weekend's stunning news about the small diamond and sapphire coronet owned by Queen Victoria, I thought it was time for us to dust off the old tiara timelines. Let's have a look at the history of this remarkable piece, shall we?

The Albert Brooch (Photo: Chris Jackson/Getty Images)

1840: Queen Victoria marries her cousin, Prince Albert of Saxe-Coburg and Gotha. Albert presents her with a large sapphire and diamond cluster brooch (usually now simply called the "Albert Brooch") on the night before their wedding. She wears the brooch on her wedding day. (The brooch is still in the royal family's collection today, and it is worn frequently by the Queen.)

Queen Margrethe II of Denmark is one of the most interesting and artistic monarchs in Europe, and her jewelry is often as intriguing and modern as she is. Today we're focusing on one of the newer additions to Margrethe's royal jewel box: the set of jewelry given to her by the people of Greenland to mark her Ruby Jubilee. The Naasut tiara and earrings, which make up a tidy little demi-parure, are modern pieces of jewelry that are especially suited to this innovative queen.

One of the simplest yet most sentimental pieces of jewelry in the Duchess of Cambridge's collection is a gold link bracelet with a single disc charm. The piece is thought to have been a gift to Kate from her stepmother-in-law, the Duchess of Cornwall.

Crown Princess Mary's Wedding Tiara

Unlike many royal brides, Crown Princess Mary of Denmark's tiara debut wasn't on her wedding day. She'd already worn a grand tiara -- the diadem from the Danish Ruby Parure -- during her pre-wedding celebrations. Even so, she did wear a brand-new (to her) sparkler on her wedding day: a romantic, convertible diamond tiara.

10. The Duke and Duchess of Cambridge visited YoungMinds, a charity in London dedicated to mental health support, on Thursday. Kate wore her daytime jewelry uniform: Kiki McDonough earrings (the "Lauren" pair), her usual rings, and her Cartier watch.

It's hard to believe, but 2001 was a whole 15 years ago! Fifteen years ago today, Crown Prince Haakon of Norway married Mette-Marit Tjessem Hoiby in Oslo's cathedral. Here's a look at some of the jewels worn by the bride and her royal guests.

For a series of engagements in Luton this morning, the Duchess of Cambridge pulled out a familiar pair of earrings from her jewelry box: her sapphire and diamond cluster drops.

The Danish Ruby Parure Tiara

When Denmark's crown princess attends glittering events like royal weddings, state banquets, or the annual New Year's courts, she often wears a distinctive tiara of rubies and diamonds. The tiara isn't only beautiful -- it has an amazing backstory that travels back two centuries to France and the extravagant imperial coronation of Napoleon Bonaparte.

The christening of Prince Alexander of Sweden, the son of Prince Carl Philip and Princess Sofia, is scheduled to take place in the chapel of Drottningholm Palace in Stockholm on September 9. Ahead of the christening date, the Swedish court has released two new pictures of baby Alexander and his parents.

New August Birthstone: The Spinel

August babies, you are in luck: you have a brand-new birthstone! In June, the Jewelers of America and the American Gem Trade Association announced that August would now have two birthstones: the traditional peridot and the spinel.

Spinels come in a variety of colors, but the most famous hue of all is red. These red spinels were long known as "balas rubies," and in fact, for centuries, spinels were regularly mistaken for rubies. The technology to distinguish between the two stones wasn't available until the 1700s.

Because of this, many of the great "rubies" in royal collections from centuries past were actually spinels. Today, we're looking at four of these great red stones, which are part of crown jewel collections from the UK to Iran and places in between.

Another VICTORIA Tiara Teaser

— Dan McCulloch (@danmcculloch) July 29, 2016

Thanks to the image above (which was tweeted by Dan McCulloch, producer of the upcoming ITV/PBS series Victoria), we've got yet another glimpse of a tiara used in the production.

Looks like this time we've got a version of the Girls of Great Britain and Ireland Tiara, albeit sort of cut in half. I know I don't need to tell dedicated readers why this made me smile a little, but quickly: Queen Victoria never owned this tiara. It was made as a wedding present for Queen Mary in 1893, and only two royal women -- Queen Mary and Queen Elizabeth II -- have ever worn it in public.

Jewel History: Princess Christian's Silver Wedding Tiara (1891)

"London Gossip"

(originally appeared in the Taranaki Herald, 18 Sep 1891)

At Cumberland Lodge [1], the residence of Prince and Princess Christian [2], the silver wedding presents were impressively displayed in several of the best rooms. There is nothing especially striking or even beautiful about the architecture of Cumberland Lodge, where "the Christians" have resided for the past sixteen years, and the restored portion (rebuilt after the fire of 1869) has evidently been erected with an eye to economy.

Kate's Jewelry Box: The Amrapali Lapis Earrings

Although many of the Duchess of Cambridge's earrings are small and delicate, she does have some major statement earrings in her collection. Today's pair, her lapis and diamond earrings from Amrapali, are some of the most colorful and interesting of her larger jewels.

Since she officially became an HRH in 2008, Princess Marie of Denmark has worn precisely two tiaras. While she debuted the silver and amethyst Flora Danica Tiara in 2014, today's tiara, a diamond floral piece that has been in the family for several generations, is still the workhorse of her collection. From her wedding to the annual Danish New Year’s Courts to family celebrations, it’s been all floral all the time for Princess Marie.

The Alexandrine Diamond Drop Tiara

Looking for the weekly jewel roundup? It's the summer slow season, so we're taking a week off. The top ten jewels of the past fortnight will be up next Friday!

One of the perks of being a royal princess is that you often receive your very first tiara on your eighteenth birthday. Some of them are dinky (like Crown Princess Victoria’s birthday tiara), some are modern (like Princess Märtha Louise of Norway’s birthday tiara), and some, like this one, are historic family pieces. On her eighteenth birthday, Margrethe II of Denmark’s parents gave her this diamond drop tiara, which originally belonged to her grandmother, Queen Alexandrine.

The Spanish royals aren't the only ones who have been enjoying a holiday in Palma de Mallorca recently. Two members of the extended princely family of Monaco -- Pierre Casiraghi and his wife, Beatrice Borromeo -- have also been spending part of August in Spain. Today is Beatrice's birthday, and to celebrate, let's have a look at the jewelry she wore at the Copa del Rey Mapfre Sailing Cup Awards on August 6.

As some of Europe's queens and queens consort are beginning to age, they frequently reach for smaller, lighter tiaras. In Denmark, Queen Margrethe II has begun to wear her small turquoise bandeau more often for state banquets and other diplomatic events that require a tiara.

A Wedding Tiara for Eugenie?

Rumors are rife at the moment that an engagement announcement may be imminent for Princess Eugenie of York. Eugenie, who is eighth in line to the British throne, is an associate director at a London art gallery. She's been in a relationship with Jack Brooksbank, who runs a nightclub in London, for six years.

This weekend, Camilla Tominey broke the news that Eugenie is planning to move to a cottage on the grounds of Kensington Palace ahead of a wedding to Jack in 2017. Though the Duchess of York swiftly denied the story, the move to KP has been widely reported, and Tominey has stood by her sources on the entire story.

Jewel History: Russian Art Show (1935)

"Russian Art Show"

(originally appeared in the New Zealand Herald on 3 Aug 1935)

The last pathetic relics of the luxury and splendour with which the pre-war Russian aristocracy loved to surround itself were recently on view at No. 1 Belgrave Square -- just two doors away from the residence of the Duke and Duchess of Kent [1], writes a London correspondent. Because of her Tsarist ancestry [2], the Duchess was called upon to perform the opening ceremony and make her first official speech in England since her marriage. This was one of the shortest on record. She simply smiled and said: "I have much pleasure in declaring the Exhibition open."

The oak tree is an important symbol for the Middleton family, and oak leaves and acorns feature prominently in several pieces of the Duchess of Cambridge's jewelry. The most famous of her oak jewels are undoubtedly her wedding earrings, but she also has a gorgeous oak leaf and acorn brooch.

The Dutch Laurel Wreath Tiara

In ancient Greece, victorious athletes (and poets -- hence "poet laureate"!) were crowned with wreaths of laurel leaves. Laurel wreaths have been Western cultural symbols of victory for centuries since, so it shouldn't be surprising that the wealthy and powerful have often commissioned their own diamond versions of laurel wreaths. The style is still so associated with ancient Greece that, in French, these tiaras are often called bandeaux à la grecque. Today, we're looking at the diamond laurel wreath tiara that belongs to the Dutch royal family.

There was a bit of shocking aristocratic news out of London yesterday: Gerald Grosvenor, the 6th Duke of Westminster, died suddenly at the age of 64. The Grosvenors are one of the richest families in Britain, and they have ties of friendship and family with the royal family. They also have a number of gorgeous tiaras in their family collection. Today we're honoring the memory of the late Duke by looking at one of the tiaras he purchased himself: a pink spinel and diamond tiara that was created in the world of imperial Russia.
