Absolutely beautiful

My fiancé proposed to me with this ring yesterday at Fort Sumter National Monument in Charleston, SC. It was absolutely beautiful. This ring is so gorgeous. The band is perfect and the moissanite is stunning. I could not be happier with my ring. I love that it is ethically sourced as well.

Beautiful ring!

The 1.5ct size is a beautiful setting for a size 4.25 ring! The only thing to keep an eye out for is that these three stone settings may not work with all styles of wedding bands. If you have a particular image about how you want this to look with a wedding band consider the wedding band options before buying to make sure it will look how you want it to look!

Custom bands and excellent customer service

My engagement band is very low set so I had a hard time finding a wedding band that fits around it. My best option was to do the open pave band, but with a custom gap width. Throughout this process, Liz was extremely helpful and patient. There is also a lot of consistency in who you talk to via chat, email, etc. I had worked with Liz the whole time; she guided me through figuring out what size gap I need and any other ring accommodations to consider that I hadn’t thought of. She was super personable, as well. The ring turned out perfect, and I received it very quickly. Everything was all around a pleasant experience - highly recommend!

Stunning Quality & Exceptional Service!

I absolutely love Gema & Co! From the very first inquiry, their team was incredibly communicative, patient, and helpful throughout the entire process. The Oval Halo ring in 14K yellow gold is absolutely stunning — the craftsmanship is impeccable and the stone is even more beautiful in person than in the photos. The quality far exceeded my expectations and it arrived beautifully packaged. If you're looking for a jeweler who truly cares about getting every detail right, look no further. I could not be happier and will definitely be a returning customer!

I was very skeptical at first with it being an online order for an engagement ring but I did the research and they communicated so well and I am so glad I chose them. She was beyond thrilled when she saw how beautiful it was. Definitely would recommend.

Frequently Asked Questions About Cushion Cut Moissanite Engagement Rings

Is moissanite good for an engagement ring?

A cushion moissanite ring is an excellent choice for an engagement ring because of its durability and lasting sparkle. With a hardness of 9.25 on the Mohs scale, moissanite is almost as strong as a diamond and highly resistant to scratches. It offers impressive brilliance and fire, making it stand out in both natural and artificial light.

What is the best cut of moissanite for an engagement ring?

The best cut depends on personal preference, but round and cushion cut moissanite engagement rings remain the most sought-after. Round cuts are celebrated for maximum brilliance, while a moissanite cushion cut ring enhances fire and creates a balanced glow with its rounded edges. The cushion cut also delivers a romantic look with a vintage-inspired feel that many couples adore. Both cuts showcase moissanite’s brilliance, giving buyers excellent options for style and sparkle.

Is cushion cut good for moissanite?

A moissanite cushion cut stone is a great choice for engagement rings because it highlights the gem’s natural brilliance. The softened square shape with rounded corners creates a harmonious blend of classic design and modern elegance. This cut also enhances moissanite’s rainbow sparkle, offering a lively yet timeless appearance. It’s a versatile option that works beautifully in solitaires, halos, or three-stone settings.

Are there downsides to moissanite?

Moissanite displays more colorful fire than traditional diamonds, which some might find too different. However, when choosing between cushion cut engagement rings, moissanite is often preferred due to that enhanced brilliance and moissanite's ethical, affordable nature.

What cut of moissanite sparkles the most?

Round and cushion cut moissanite rings are both known for exceptional sparkle. Round cuts are mathematically designed to reflect the most light, making them the top choice for brilliance. A cushion cut offers slightly less sparkle but adds a softer, romantic glow with its rounded edges. Many couples prefer cushion cuts for the balance of sparkle and personality, especially when paired with a halo or side stones.

What does a cushion cut engagement ring say about you?

A cushion cut engagement ring often reflects someone with an eye for timeless style and a love of subtle individuality. Its blend of square shape and rounded corners conveys both strength and softness, symbolizing balance in a relationship. Choosing this cut suggests you value romance, heritage, and elegance while still appreciating a modern edge. It’s a statement of personality as much as it is a symbol of love.
