Emerald Cut Engagement Rings — Timeless, Forever.

Elegant, timeless, and effortlessly sophisticated — an emerald cut engagement ring is perfect for those drawn to clean lines and quiet luxury. With its distinctive step-cut facets and open, mirror-like appearance, this vintage-inspired shape exudes refined clarity, offering a subtle, glassy gleam rather than a bold sparkle. Perfect for the minimalist at heart, its elongated silhouette flatters the hand and suits a wide range of settings — from sleek solitaires to Art Deco-inspired halos and everything in between.  

At Cullen, each emerald cut ring is handcrafted in our Australian workshop using ethically sourced materials and lab-grown gemstones. Explore the collection online or begin your journey in one of our showrooms with a personalized design consultation — whatever the process, we're here to help you cherish your forever love with the ring of your dreams.
