A diamond, they say, is forever. Why? Because they're timeless, iconic and as the hardest crystal on the planet, diamonds are also incredibly resilient. So when you buy one, you want to buy the right one. But with so many options, designs and prices, you need someone to cut through the clutter. Thankfully, it doesn't have to be so overwhelming and stressful.

Couple, the first luxury brand selling lab-grown diamonds, not only makes the process simple, but the personalized attention actually makes the experience a pleasure. They've reimagined the entire process of shopping for an engagement ring. They only source conflict-free, lab-grown diamonds, so you get a stunning high quality, ethically made diamond that is atomically identical to a mined diamond, and also 35% larger for your money. And every ring is hand-crafted in New York City by classically-trained jewelers—bridging new technology with old school luxury craftsmanship.

What really sets them apart is their Diamond Concierge service, offering expert guidance throughout the process—from learning about the 4C's (color, cut, clarity and carat) of diamond quality to the intricacies of the design process. You'll receive a uniquely customized design with 3D renderings that all but ensures you will love the ring before proposing, along with complimentary resizing and returns.
