Mine is really simple.
I have a gold coin pendant with a toggle clasp that I got in Greece. I've had so many comments / compliments. It goes well over tops or under a shirt.
I have a specfic colour for jewellery if I ever wear colour, which is turquoise. It really suits me. So, slightly dressier I have a turquoise beaded chain, sort of hexagonal beads, hard to explain, has a toggle back like the other one, was also from Greece. If I'm feeling the bling I layer with first chain
I also have a delicate chain with pearls from Boden for super smart.
Earrings I have tiny turquoise teardrops from Oliver Bonas. The stone keeps falling out and I keep taking exchanging them so I probably need to spend more.
I have two piercings in one side and one in the other. No idea why. I actually have 3 and 2 but I let them close.
I also have some blingy rainbow circle drop earrings for dressier also from Oliver Bonas.
A toggle clasp pearl bracelet.
I find bracelets and rings very hard to wear as I will constantly absent mindedly take them off.
Colour is very personal. I had my colours done and I am bright spring, so light gold and rose gold are nice.
