Our S4394CZ – 3.9mm CZ Post Earrings with Sterling Silver .8mm thick posts.  Clutches included. These earrings do not have a drop ring or connection point. Use them with earring jackets or just wear them alone as simple stud earrings. Because of its low cost, durability and close visual likeness to the diamond, the synthetic cubic zirconia is a great substitution.  They are 1.7 times denser than a diamond with just a slightly less refractive index.  These studs have no drop ring. They will work well with interchangeable earring jackets. Or upsell them as complements to statement earrings as part of an earring suite set. For when you require the Most from A Post!
