Discover Simon Alexander's cushion cut engagement rings — designed in our Adelaide boutique, Australian made, and made to order. With softly rounded corners and a romantic, antique-inspired sparkle, the cushion is enjoying a real resurgence — a shape that feels both vintage and current. From delicate solitaires to diamond-set halos, we design and craft each ring to suit you.

Prefer a lab-grown stone? We also create lab-grown diamond engagement rings — real diamonds, IGI certified, made to order. Natural diamonds come with GIA certification; the choice is yours, certified either way.

Cushion Cut Engagement Rings in Adelaide

The cushion cut blends a soft, pillow-like outline with brilliant facets that catch the light beautifully. With 25 years of experience, Simon Alexander works with you to choose the right stone and design a setting that's entirely your own — sketched, drawn up in detailed renders for your approval, then Australian made and finished by our team.
