Our elongated cushion cut lab created diamond simulant cubic zirconia stud earrings bring another level of adornment to your ears. With their unique and rare shape, they provide so many additional benefits beyond just beautiful stud earrings. Their shape is elegant and differs from the norm, making for a great conversation piece. Their faceting and brilliance rival any radiant cut or faceting pattern. A rarely seen diamond shape like these will make you the envy of your friends, everyone will want to ask you about them and ask where you got them. This premier shape with its exclusive cut features the perfect combination of a cushion cut and an oval or emerald rectangular shape. This hybrid cut has soft edges that beautifully highlight the antique style of the cushion cut in an elongated or oval fashion and can also be referred to as a cushion cut rectangle, antique cushion cut, oval cushion cut, hybrid cushion cut, or emerald cushion cut. Even though it is inspired by a vintage shape, the modern translation and faceting bring this shape into ultra-modern contemporary times. They will add the perfect amount of brilliance to your wardrobe and brighten up your face. Perfect for short or long hair, daytime or evening wear, elongated 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 elongated cushion cut stud earrings features 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.

    I love these earrings. The fact that they are such a unique shape makes me love them even more. Everyone asks me about them because they are a shape they don't recognize. Great brilliance and a very nice setting. The big backs are a life saver too.

  • They match my diamond engagement ring 5

    I have a cushion shape like these in my engagement ring and wanted studs to match but way too expensive in real diamonds. These look amazing. Better color than my diamond and they have a lot of facets and shine.

  • My favorite earrings 5

    I have a lot of earrings and a few diamond studs. These are so fun to wear. They look amazingly real and everyone compliments and asks me about their unique shape.

  • Ordered for her B-day and she liked them a lot 4

    The earrings were a hit with my lady. The delivery was messed up by the post office and it took forever to get them to redeliver the package. I almost missed the gifting date but it all worked out. Ziamond should use Fedex or UPS instead.

  • Love these so much 5

    I added these elongated cushion cuts in 1.50 carat each set in 14k white gold. They look amazing on and I love the unique shape.
