    I definitely recommend Lucenjuri! Take it from me, I was skeptical and overthought a lot about where I am going to purchase a ring. Until I came across Lucenjuri, this company made things a lot easier for me and boosted my confidence in choosing the ring that my bride-to-be will bear forever.

    I had the BEST experience with Lucenjuri! Their website is one of the easiest I've used when it comes to vetting diamonds by specific criteria. My ring arrives today and it is absolutely stunning. I couldn't stop staring! Can't wait to purchase with them again.

    Why Choose a 1 Carat Lab Diamond Engagement Ring?

    The 1 carat round brilliant cut diamond engagement ring is one of the most popular choices. The standard round brilliant cut consists of 58 precisely angled facets that give the diamond the ability to reflect the maximum amount of sparkle and fire. Round diamonds in both the solitaire and halo settings evoke a classic elegance.

    1 Carat Emerald Cut Diamond Engagement Rings

    A 1 carat emerald cut diamond ring is loved for its sleek, rectangular shape and elegant step-cut facets. It gives a sophisticated, vintage-inspired vibe and looks amazing in solitaire or three-stone settings. The long and narrow shape of the emerald cut makes fingers appear longer and slimmer, which is often desired by brides-to-be.

    1 Carat Oval Cut Diamond Engagement Ring

    The oval cut diamond engagement ring is a perfect choice if you want your 1 carat ring to appear larger. It has a longer shape (in a diamond) which covers more of your finger than a similar weight round shaped diamond. Oval shapes can be set with hidden halos and delicate pavé bands, and look beautiful!

    1 Carat Princess Cut Engagement Ring

    A princess cut diamond ring offers a bold, modern square shape with brilliant sparkle. Its geometric lines make it a perfect choice for brides that are looking for a contemporary feel, and looks beautiful in both solitaire and channel set bands.

    The best of both worlds, the pear cut shows both round and marquise shapes in a unique teardrop style. A 1 carat pear diamond engagement ring has a larger look overall than its actual weight. It is often set in halos or solitaire rings for a romantic, eye-catching style.
