Soft rounded edges with pointed corners make our cushion cut square laboratory grown diamond alternative cubic zirconia stud earrings coveted and desired by so many. The shape is a combination of the brilliant round cut and the popular princess cut, resulting in a wonderful and unique diamond shape. They are set in a low-profile four prong basket setting. The larger they get, the better cushion cut square studs look. They add the right amount of brilliance to your wardrobe and brighten up your face every time you put them on. Perfect for short or long hair, daytime or evening wear, cushion cut diamond look stud earrings are extremely versatile. All the popular carat sizes are offered and additional larger carat sizes are available via special order. Various colors are also available via special order, see the menu options. Standard posts with friction earring backs are included or upgrade to our highly recommended pair of jumbo large earrings backs for added comfort and support to help earrings sit as low as possible to your ears. For extra security, you can choose screw backs with threaded posts. Each pair of cushion cut square stud earrings feature Ziamond's Russian formula lab created diamond simulant cubic zirconia that are hand cut and hand polished to exact diamond specifications. Earrings are sold in pairs and the carat size listed is for each stone. Total carat weight refers to the total for the pair of earrings.

    These were my stocking stuffers and they are truly gorgeous. I love the cushion shape, and the big earring backs are a game changer for me.

    From the cut to the setting, these are amazingly beautiful. Especially for the price.

  • Beautiful earrings 5

    I always loved this shape and last month I ordered them. They arrived fairly quick and they look amazing. Just like the picture on their site.

  • Cushion cut is my favorite 5

    Posted by Paula M. on Jul 24th 2023

    I wanted a pair of diamond cushion cut studs to go with my cushion cut engagement ring. I figured I would go the cz route and found Ziamond. These earrings were just perfect and they have even better color and clarity than my diamond. The shape to me is perfect.

  • My everyday earrings 5

    Posted by Valarie H. on Feb 13th 2023

    I wear these everyday and I love them. The shape and cut of the cushion cut is really spectacular compared to the real diamond round studs I used to have
