Wow – twenty years together! That’s impressive. You’ve worked and crafted and created something beautiful. And yet all relationships need constant care not to slip through your fingers and break. So china or porcelain are perfect exemplars of elegance and delicacy.

Platinum is a precious metal with a wide range of uses, including jewellery, catalytic converters, and pacemakers. It’s expensive because there are only about five parts per billion by weight in the Earth's crust. The best watchmakers use platinum for producing their limited-edition watch series, appreciating a substance that neither tarnishes nor wears out (relative to gold).

Platinum is pricy – the Queen Mother’s crown was held together by the stuff – so you may have to find jewellery with a small amount of the metal or think laterally. 

Emerald gemstones have been synonymous with the colour green since ancient times. A fine emerald is an impressive sight, and this member of the beryl family deserves its place among the traditional ‘big four’ gems along with diamond, ruby, and sapphire. Called by some the “Stone of Successful Love,” emeralds are gems of inspiration and infinite patience, embodying unity, compassion and unconditional love. Best grab one then!

Any jewellery featuring emeralds: bracelets, bangles, cuffs, necklaces, pendants, earrings, rings are great gifts for your 20th anniversary. They are feminine and hopefully she will wear and wear them with fondness.  

Don’t worry about the name. This pretty flower’s botanical name, Hemerocallis, means "beauty for a day", and indeed most daylily flowers open in the morning and die by nightfall. However, each flower stem (also called a scape) typically has at least a dozen flower buds, so the plant stays in bloom for several weeks.
