Lab-Grown Diamond Engagement Rings That Look Luxurious & Cost Less

Lab-grown diamond engagement rings offer the same brilliance, durability, and beauty as natural diamonds, but at a significantly lower price. At Diagaa, you’ll find certified lab-grown diamond engagement rings designed to celebrate your love story without stretching your budget. These rings combine luxury, quality, and affordability, making them a perfect choice for couples seeking value without compromising on style.

Lab-grown diamond engagement rings are real diamonds created in controlled laboratory environments. They cost 40–60% less than natural diamonds while offering identical sparkle, hardness, and longevity. Diagaa ensures every ring comes with third-party certification, 25% off, full customization, and free shipping across the USA, providing transparency, convenience, and value to every buyer.

Why Choose Lab-Grown Diamond Engagement Rings?

Lab diamond engagement rings are chemically and visually identical to mined diamonds, with the only difference being price. They offer the same fire, brilliance, and hardness (10 on the Mohs scale) as natural diamonds. Certified by trusted third-party gemological labs, these diamonds are ethical, conflict-free, and provide more value for your budget.

Cost of Lab-Grown Diamond Engagement Rings

The price of lab-grown diamond engagement rings depends on carat size, cut, color, clarity, and setting. A 1-carat lab-grown diamond typically costs $1,500–$3,000, while 2-carat diamonds are often priced lower than a 1-carat natural diamond. Overall, buyers save up to 60–80% compared to mined diamonds.

Popular Lab-Grown Engagement Ring Styles

Classic Solitaire Engagement Rings

A solitaire ring features a single diamond to highlight pure brilliance. Available in round, oval, princess, and cushion cuts, this timeless design focuses on the sparkle and elegance of the center stone.

Halo Engagement Rings

Halo engagement rings surround the center diamond with smaller diamonds, enhancing the stone’s size and brilliance. This design creates a dazzling effect that captures attention from every angle.

Custom Lab-Grown Diamond Rings

Customize your ring by selecting diamond shape, size, and quality. Choose your preferred metal type and setting style, with expert guidance to create a unique ring that matches your vision perfectly.

Carat Size and Shape Options for Every Budget
