Johnathan Cardillo is a luxury accessories brand handcrafted in Los Angeles by a skilled artisan. Most of our wares are made-to-order or produced in small batches. Johnathan's aim is to design jewelry that is upscale, edgy, and sure to elicit a compliment when worn. We work exclusively with sterling silver and 18k gold.




After falling in love and having his heart broken, Johnathan set out to design a pendant that would serve as a constant reminder that love is dangerous and the heart is fragile. Something that he could wear around his neck to guard his heart, like a small dagger. Thus, the spike collection was born, and has been protecting hearts around the world ever since.
