Open Triangle Delta Pendant Necklace in 14K Yellow Gold

The clasp here is a spring ring rather than a lobster, and that is a decision rather than a default. A spring ring is a hollow circle with a spring-loaded gate riding inside it, smaller and flatter and lighter than a lobster claw, so it disappears at the back of the neck instead of sitting there as a lump. It asks slightly more of your fingers and much less of the necklace's line.

The pendant is an open inverted triangle, and the opening costs it nothing structurally. A triangle is the only polygon that cannot be deformed without bending one of its own sides, so an outline of 2.2 grams keeps its shape in a drawer where an open circle of equal weight would slowly go oval. Every frame is strong in the shape it is built as. Triangles are strongest of all.

Delta is the symbol mathematicians and engineers use for change, the difference between what a thing was and what it now is. Worn, it reads as geometry first and meaning second, which is the correct order for a symbol you intend to put on every morning. It hangs from an 18-inch link chain.
