The easiest way to upstyle a casual weekend outfit, office ensemble or simple black dress? Acccessorise, accessorise and accessorise! If we could revise high school curriculum, we’d take out a little bit of that trigonometry (Isosceles triangle anyone?) and add in a few simple - yet valuable - style lessons.

If you only wear one piece of jewellery, make it a cocktail ring. Whether you go for vintage-style glamour, a contemporary knuckle duster or a gem-encrusted sparkler, it’s sure to make you - and your outfit - stand out. Here are some of our favourite statement rings to buy right now. And wear with? Everything. There’s absolutely nothing wrong with popping out for a newspaper in jogging bottoms and a cocktail ring….

statement ringsPart of London-based designer Niza Huang’s Under Earth collection, we love this unusual rose gold ring. Inspired by natural rock formations, each Irregular ring is handmade and completely unique. Huang’s spectacular petroleum rings are rather lovely too - and a very timely statement (sorry…) on contemporary society. Every piece contains a single droplet of pure petroleum magnified by mineral glass.

Sylvia Toledano is well-known for her crystal-encrusted clutches, but it’s the Parisian designer’s equally glitzy rings that have got us doing quick eat-toast-for-a-month budget calculations. This enormous agate ring is just one of Toledano’s piece making a serious style statement.

Toughen up basics and fashion-forward pieces with Bottega Veneta’s edgy blackened sterling silver ring. If you like your jewels modern and minimal, this is one for you. Also see Maison Martin Margiela’s stacked silver-tone crystal ring. Simple, elegant, effortless - plus it’s three rings for the price of one. Not quite a bargain, but if economical Margiela exists, this is it.

With summer on the way, the jewel-toned Jaipur ring from Gripoix is what we plan on wearing with ethnic-inspired ensembles, bikinis, summer dresses and even so-called ‘festival wear’. Looks particularly good with head-to-toe white linen. On a yacht.
