Other Coloured Gemstones

The Colour/Gemstones seen are barley seen so, when it is revealed it's a suprise.

(From left to Right: Princess Maxima, Camilla Parker-Bowles, Queen Beatrix, Queen Margrethe II and Martha Louise)

Some Rings that are a different Gemstones:

Queen Margrethe II of Denmark's multi Gem engagement Ring

Princess Maxima's Orange coloured gemstone (I'm thinking Williem choose this because she will be a Orange Princess)

From the way it looks the Jewels are either pink or diamonds? I am going with pink.

Princess Martha Louise's I think Ruby? and Gold ring? I don't know so I am putting it under Different Colour Gemstone.

Camilla Parker-Bowles ring that once belonged to her Husband's (Prince Charles) Grandmother: Elizabeth the Queen Mother.
