Spring
Spring looks best in bright, shiny, gold-coloured metal. Think of pure sunshine.

Wonderland Charm Necklace, Stella & Dot, £67.50 in the sale
Brushed gold shouldn’t be ruled out, but it needs to be sunshine yellow, not antique or copper.
Springs that look better in the cooler colours of their palette can also wear silver but keep it shiny and in no way tarnished.
Rose gold can look very pretty on a Spring. Again, keep the shine. Mixed metals can be really magical too.

Turquoise stones and sparkle are fabulous. Go for transparent rather than opaque stones if possible (I’m being rather fussy here, but we are going for the maximum wow factor).

Avoid anything too muted or bronzed and especially avoid the antiqued look. Copper and antique bronze will likely be too muted and deep.

For the price I suspect this lovely necklace wouldn’t last very long, but it is a great example of a Spring necklace. Bright yellow gold, high shine, and the necklace has some movement too.
Summer
Summer glows in matte, silver-coloured metal. This brushed silver necklace on Not On The High Street is a brilliant example of brushed silver making the skin glow. I suspect she’s a Summer with those ash brown eyebrows and platinum blonde hair (albeit from a bottle). It’s a shame her make-up is so distracting. The black eye liner and warm red lippy aren’t right for her. The necklace and her skin, however, remind me of moonlit milk. Perfection.

This feather necklace is pretty and smaller-scale. Brushed silver again. The soft flowing lines are very befitting.

The texture of these rings is beautiful, as is the pattern in the stones and the satin finish. Labradorite is a beautiful and unusual choice, spot-on for a Summer.

Moonstone is another beautiful and unusual gemstone. It’s misty and gentle in its appearance and has a wonderful shimmer when the light hits it.

This antique-effect silver filigree moon necklace is very pretty too.

Summers can usually get away with rose gold if they so wish, and a very pale light yellow gold as long as it isn’t very yellow at all. Shiny silver is fine, but a more matte, satin finish will always have the edge.
Perhaps rather surprisingly, Summers can wear antiqued bronze particularly if found on a compliant coat in the form of buttons. The bronze isn’t too warm and is muted, making it an interesting alternative to silver and it looks great with brown leather.
