If you’re flat out of ideas for this year’s Valentine Day, you can never really go wrong with jewellery. Here are just a few of the most interesting accessories I found.

Spell out your love and happiness with chemistry

What is love? It’s an age-old question with likely no satisfying answer. What seems certain is that nature has developed an irresistible cocktail of chemicals to help us fall in love (and hopefully pass on our genes).

Serotonin necklace

It’s one of love’s most important chemicals that may explain why when you’re falling in love, your new lover keeps popping into your thoughts. In one study, researchers discovered that serotonin levels of new lovers were equivalent to the low serotonin levels of Obsessive-Compulsive Disorder patients.

Dopamine necklace

Lovestruck couples have high levels of the neurotransmitter dopamine. This chemical stimulates ‘desire and reward’ by triggering an intense rush of pleasure.

Adrenaline necklace


The initial stages of falling for someone activates your stress response, increasing your blood levels of adrenalin and cortisol. This has the charming effect of making you sweat, making your heart race and your mouth go dry when you unexpectedly bump into your new love.

Oxytocin necklace

Oxytocin is a powerful hormone released by men and women during orgasm. The chemical helps deepen feelings of attachment, cementing relationships and making couples feel much closer to one another.

Solar system bracelet

A great unisex accessory for that special someone who always has eyes for the stars. Features all the planets, the sun, the moon, and a black hole.

DNA ring

A lovely double-helix ring that makes for a nice gift for any occasion.

Or maybe some DNA earrings

A cute X-rayed cat pendant

A beautiful pendant showing the detailed skeleton of a feral cat finished with black epoxy. Perfect for people who love cats and radiology.

Or, if she likes ravens more, this:

Nerve cell bracelet

Make a statement with this brainy bracelet shaped like a neuron.

Anatomical heart charm

If you’re going for the anatomically correct representation of “I heart you.”

Octopus tentacle pendant

The octopus is the only animal that has a portion of its brain (three quarters, to be exact) located in its (eight) arms. Without a central nervous system, every arm “thinks” as well as “senses” the surrounding world with total autonomy, and yet, each arm is part of the animal. Offer this gift to that special someone.

Or some 3d silver tentacle earrings

Octopi are extremely romantic. After they mate, their life has no other purpose and ends. Let your love for her never end.

Electrocardiogram EKG pendant

Because our lifeline would be flat without someone special to share life’s most intimate moments.

Or a lifeline ring

For when she makes your heart skip a beat.

Dino T-Rex necklace

An adorable piece, a testament to a love so resilient it should be in the fossil record.

Or maybe just a badass T-Rex skull

A stethoscope bracelet  

For all the moments she had listened to your heart and soothed it just like a cardiologist.

Microscope Dangle Earrings

She, as a true scientist, has looked inside your soul so many times and made you feel complete and safe. These earrings are for the special girl that always looks past all the defects, and sticks close to you whatever happens.

Sterling silver snowflake pendant

If she is a meteorologist, she sure knows how to make your heart melt every time she looks at you.

Moon Phase Statement Necklace 

Because you love her to the moon and back.

A collection of geometric animal pins

For biologists, veterinarians, or simply all animal lovers. Pretty cute, right?
