Light is what these necklaces are for. Every piece here is set with stones that catch it: cubic zirconia in tennis lines, solitaires and pavé pendants, birthstones, and pearl accents, in 14k gold plating, silver and select solid gold. Choose a solitaire for one clean point of light at the collarbone, or a tennis line when you want it to run all the way around. Each product page names the stone, so you know exactly what you are choosing. Every listing gives the lengths available.
