Lab-Grown Princess Cut Diamond Engagement Rings

Celebrate your love with the modern brilliance of a princess-cut lab-grown diamond engagement ring from Joshua James. Known for its sharp, clean lines and dazzling fire, the princess cut is one of the most popular diamond shapes, offering a contemporary yet timeless appeal. With its precise faceting and exceptional light performance, this square-cut diamond maximises brilliance, making it a striking choice for an engagement ring.

A lab-grown princess-cut diamond ensures a higher-graded stone with superior clarity, colour, and precision, enhancing its brilliance. Offering the same radiance and resilience as natural diamonds, lab-grown diamond options provide a larger, high-quality stone at a better value, all while being a more ethical and sustainable choice.

From sleek solitaires to dazzling halos and diamond-accented bands, our collection is available in 18ct white, yellow, and rose gold, as well as Platinum 950. Each ring is set with an IGI-certified lab-grown diamond, guaranteeing exceptional quality. Book a consultation and discover the perfect princess-cut engagement ring to represent your love story.

Additionally, our hallmarked precious metals guarantee quality and confidence in your purchase.

What to Consider When Buying a Lab-Grown Princess Cut Diamond Engagement Ring?

A princess cut engagement ring, whether lab-grown or natural, is a sleek, modern alternative to the classic round brilliant cut. When choosing your lab-grown princess ring, keep these factors in mind:

  • Prioritise Cut Quality: The princess cut features brilliant-cut facets, maximising sparkle and fire. A well-proportioned and expertly finished lab-grown princess cut diamond will create mesmerising light patterns and exceptional brilliance.
  • The 4Cs Matter: Like all diamonds, it's important to balance cut, clarity, colour, and carat weight. Due to the princess cut’s sharp corners and brilliant cur facets, ensuring good clarity is essential to maximise sparkle and minimise visible inclusions.
  • Carat Size & Halo Consideration: Thanks to lab-grown diamonds, you can opt for a larger stone without exceeding your budget. However, when choosing a halo setting, be mindful of size proportions to maintain both beauty and practicality.

A lab-grown princess cut diamond engagement ring is a stunning choice for those seeking a bold yet timeless design. Browse our exquisite collection at Joshua James and find the perfect symbol of your love.
