The black bead necklace is adjustable to approx. 18-1/2". The black and clear crystal necklace is 21". This piece might be vintage, it has an older type of clasp. It has a delicate beauty you don't find in many necklaces. The hematite necklace is two tiered and is adjustable to 18". It has a mixture of large and small black crystals and none of them are missing. The hematite bracelet has a chin design on to of a flat band. It catches the light very nicely. It is a generous medium size. The silver cuff bracelet is also a size medium and has beautiful swirl design with an "x" in the middle. It is very shiny and eye catching. The black bead and crystal stretch bracelet is probably a small. I have medium sized hands and I can fit it on my wrist but it is a bit tight. This also has no missing crystals. All these pieces mix and match perfectly. You can have fun trying different combinations. Keep some or all and gift or resell the rest.
