The official gemstone for a 20th wedding anniversary present is the emerald. Like the radiant ruby being the gift for 40th wedding anniversaries, emeralds are cherished by many as a symbol of true love. This gemstone is believed to represent harmony, loyalty and domestic bliss, all of which are key ingredients for building a happy life. This is why emerald jewellery can be such a beautiful choice for a 20th wedding anniversary present, with popular choices including emerald studs, pendants, bracelets and rings. The velvety hue of an emerald also recalls the beauty of nature, with the gemstone also believed to symbolise growth and renewal. Both are needed in order for a marriage to last, always evolving and learning to change with one another as the years pass. Giving your partner an emerald ring in its namesake cut can hold an incredible amount of significance, combining such qualities as growth and love with the emerald cut's sturdy foundation of peace and stability. An emerald eternity ring can reaffirm your love and commitment to one another, while pairing emeralds with rows of radiant diamonds – another classic symbol of everlasting romance – can also be a great way to spoil the love of your life.
