Some British Royals...

Queen Alexandra of Great Britain's three daughters, Princesses Maud, Louise and Victoria. Maud later became the first Queen of independent Norway, and Louise married the Duke of Fife.

Diana Princess of Wales wearing the Cambridge Lover's Knot tiara. I think it is significant that the Queen gave her such a magnificent tiara to wear, even though we all know that the vaults underneath Buckingham Palace house an amazing treasury of gems the family hasn't worn for decades.

Diana wearing the diamond Spencer Family Tiara. Her brother, being the dick that he is, took it back from her when he married his first or second wife, and in photos, you will notice that after 1994 or around there, Diana stopped wearing the Spencer tiara and only wore the Cambridge Lover's Knot. She also turned an emerald and diamond choker, that was an heirloom of Queen Mary's, into a tiara, but she must have died before she ever wore it, since there are no photos of her in it.

Princess Anne of Great Britain. I never have Anne on here! She's a great lady, she does so much charitable work for the kingdom. She is pictured in her grandmother Princess Andrew of Greece's diamond Greek meander tiara, with it's Greek key pattern designs.

Princess Anne on her marriage to Captain Mark Philips. She is wearing the diamond fringe tiara that the Queen wore on her own wedding day.

Bandeau Tiaras

 A gold and enamel bandeau tiara with large aquamarines strategically placed around the band.

 A tiara with a design very similar to a Greek-key. A diamond wreath weaves around the design for a very petite, but elegant, design.

 An interesting geometric-design tiara made from diamonds and one large pearl in the center.

 Princess Andrew of Greece's Greek Key pattern tiara. It is most often worn by Princess Anne, the Princess Royal of Great Britain, and was recently worn by her daughter, Zara, for her own wedding.

 A Persian-style carved turquoise and diamond bandeau.

 Another bandeau of similar design, with the carved turquoise leaves and diamonds.
