$8 Garage Sale Brooch Fetches $26,000 At Auction

The owner of the vintage brooch gave it to her daughter to wear to church. She later placed it in the bottom of her purse and forgot about it. On a chance visit to a jeweler many months later, she pulled out the brooch. The jeweler told her it was a piece of fine jewelry and the diamonds were real.

A sapphire and diamond ring by Stephen Russell with a 5.33-carat cabochon sapphire, set within a frame of old European cut diamonds sold to an online buyer for $235,000. A ring featuring a 7-carat oval-shaped modified brilliant-cut emerald, flanked by similarly cut Fancy Vivid Yellow diamonds sold for $225,000.

Jewel Scarab Beetles

The ornate beetles are highly valued by collectors.
Why central-American jewel scarab beetles look like they are made from pure gold has been uncovered by physicists at the University of Exeter. The golden jewel scarab beetle Chrysina resplendens has evolved an exoskeleton that contains intricate nano-structures that are responsible for its appearance.

Discovered in February last year in eastern Angola, the 404.20-carat rough diamond — named the "4 de Fevereiro" — was also the largest found so far in the southern African country.

Most expensive Antiques Roadshow find is Faberge flower

The most expensive ever Antiques Roadshow find has been revealed as a Faberge flower gifted to an army regiment - and valued at £1m. Tatiana Fabergé the Swiss based great-granddaughter of Peter Carl Faberge knew it was a botanical study created by Fabergé in Imperial Russia during the early 20th century. She did a little research and found its history. A spokesman for Faberge added: "Only about 80 of Fabergé’s botanical studies are known to have survived. In the form of pear blossom in a vase, its chased and engraved gold stem is placed in in a rock crystal vase carved so it appears to be half full of water. "The six flowers of blossom are also gold which have been enamelled white with shades of pale pink. Their stamens are oxidised silver with a diamond at the centre. "The leaves are carved nephrite. Georgina, Countess of Dudley presented the study to The Queen’s Own Worcestershire Hussars, QOWH, in the early 1900s as a regimental trophy. "Three pears feature on the county’s Arms, hence the choice of pear blossom.

The Czech Crown Jewels

The Czech Crown Jewels (Bohemian Crown Jewels) include the Crown of Saint Wenceslas, the royal orb and sceptre, the coronation vestments of the Kings of Bohemia, the gold reliquary cross, and St. Wenceslas' sword. They were originally held in Prague and Karlštejn Castle.
Since 1791 they have been stored in St. Vitus Cathedral at Prague Castle.
The Crown Jewels are permanently kept in Prague Castle and are rarely displayed.

In the twentieth century there were nine such moments in history; the last time was in 1998 to mark the 80th anniversary of the establishment of an independent Czechoslovak Republic.

The Duke of Bohemia (c. 907 – September 28, 935), or Wenceslas I, was the duke of Bohemia from 921 until his assassination in 935, purportedly in a plot by his own brother, Boleslav the Cruel.

His martyrdom, and the popularity of biographies, quickly gave rise to a reputation for heroic goodness, resulting in his being elevated to sainthood, posthumously declared king, and seen as the patron saint of the Czech state.
Wenceslas the martyr was canonized soon after his death, due to several miracles that were said to have occurred.

In 2000 more than a thousand years after his death, Wenceslas’ skull was placed on a red velvet pillow by the Archbishop of Prague to commemorate the declaration of September 28 as a public holiday.

Taafeite (BeMgAl4O8) is a very rare beryllium magnesium aluminum mineral. No other mineral has both beryllium and magnesium in its composition. Often misidentified as spinel, the gemstone was first discovered already cut and polished in Dublin, Ireland in 1945. Confusion between spinel and taaffeite is understandable as the two share very similar physical properties. The crucial difference is that taaffeite is doubly refractive while spinel is singly refractive. The gemstone is mainly found in alluvial deposits in Sri Lanka and Tanzania.

Sri Lankan Taaffeite
Taaffeite forms pink, mauve, or lilac, red to brown transparent to translucent hexagonal crystals. It is very hard, 8 on the Mohs scale.
