Also known as the Russian Fringe tiara, this was a silver wedding anniversary gift on behalf of 365 peeresses of the United Kingdom. The then-Princess Alexandra, known as Alix, had specifically requested that it be of the fashionable Russian style of a peasant girl's headdress. It was inspired by her sister, The Empress of Russia, who had an identical one. It was made by Garrard, with 61 platinum bars graduating from the center and set with 488 diamonds. Queen Mary and Queen Elizabeth II favored this tiara at many a royal occasion.

The top two players from each group advance to round 2

The Diamond Group

Diamonds are the hardest substance on earth. They are more brilliant than any other natural gem. They have a brilliant luster, and also exhibit dazzling color flashes known as "fire". This is caused by dispersion, where light enters the diamond and splits into the colors of the spectrum. Only 20 percent of mined diamonds are used in jewelry, as most are unsuitable. The four Cs of diamond evaluation are: Color, Cut, Clarity and Carat Weight. Also known as "a girl's best friend." Its name derives from the Greek word adamas, which means 'invincible'. Although it is the hardest natural substance on earth, if it is placed in an oven and the temperature is raised to about 763°C (1405°F), it will simply vanish, without even ash remaining. Only a little carbon dioxide will have been released. Diamonds are a form of carbon--remember how Superman was too cheap to buy Lois Lane a diamond, so he squeeze a lump of coal in his hand until it turned into a diamond! Birthstone for April Lore: The diamond has always been linked to love, fidelity, and faithfulness and is considered a protection against poisons and plagues.

   The Emerald Group

Emerald is the green variety of the mineral beryl. Emeralds are notorious for their flaws. Flawless stones are very uncommon, and are noted for their great value. Some people actually prefer an emerald with very minute flaws over a flawless emerald, as this proves authenticity of the stone. Many emerald flaws can be hidden by treating the emeralds with oil. Emeralds may develop internal cracks if banged hard or if subject to extreme temperature change. Birthstone for May Lore: The emerald enhances love, brings eloquence, gaiety, & popularity. Brings strength, especially in old age, and restores eyesight. Enhances courage in times of trial and emotional distresses.
