When he popped the question, the then Prince of Orange chose an impressive white gold engagement ring encrusted with sparkling gems from jewellery house Steltman for his future bride.
It featured a unique oval orange diamond at the centre flanked by two emerald-cut diamonds – which has symbolic significance as it was a subtle nod to the national colour of the Netherlands.

Royal fans first caught a glimpse of the unusual ring back in 2001, but Maxima has been spotted wearing it on both her right and left hand for royal engagements since then.
It is thought that this could be because it is tradition for the bride and groom to wear their rings on both hands in some European countries. Another theory is that it represents the blended traditions of Maxima and Willem-Alexander's Catholic and Protestant backgrounds.

Some eagle-eyed fans may also have noted the similarities between Queen Maxima and Princess Eugenie's coloured engagement rings, both of which have orange tones.
Eugenie's striking ring, chosen by Jack Brooksbank in 2018, contains a padparadscha sapphire surrounded by diamonds, which gives a beautiful pinkish-orange glow.

Speaking about Eugenie's precious piece of jewellery, which contains the rarest of all sapphires which usually come from Sri Lanka, the Natural Sapphire Company said: "Nothing brings to mind blooming flowers like padparadscha sapphires. Named after the colour of a lotus blossom, the pinkish orange glow of these stones are hypnotising."
