My fiancé and I wanted to design my engagement ring together, and Marina sourced us a beautiful 1.3-carat round brilliant diamond and they set in 14k white gold. We never felt rushed and appreciated all of her guidance throughout the process. The ring turned out even better than we imagined, and we're so happy we chose Marilex Diamonds.

Working with Marilex Diamonds to create my fiancée's engagement ring was an incredible experience from start to finish. They sourced the perfect criss-cut diamond and designed the ring in 14k yellow gold with a platinum head. The entire process was seamless, and exceeded all my expectations. I recently proposed, and my fiancée absolutely loves her ring, it's exactly what she wanted. Couldn't be happier with how everything turned out.

My grandmother gave me a ring with sapphires, but I wanted something special I can wear on my wedding day as my something blue so I reached out to Marilex Diamonds on insta! They helped me create the most beautiful flower pendant and sourced a round diamond for the center all from my grandma's ring. The whole process was so easy, and she really understood my vision. Wearing something so meaningful on my wedding day made it even more special. I absolutely love how it turned out.

Silver necklace with a star-shaped pendant featuring blue stones on a black background
FROM OUR CLIENTS
After 30 years of marriage, my original wedding band no longer fit and felt too bulky for everyday wear. Marina designed and created the perfect wedding band for me with marquise diamonds. It's dainty, comfortable, and yet still has the perfect amount of sparkle. It's exactly what I envisioned and I finally have a wedding band I can wear every day again.

FROM OUR CLIENTS
I purchased the Celeste pendant in 14k yellow gold with the peridot stone as a birthday gift to myself, and I absolutely love it. It's timeless and perfect for everyday wear. The pop of green is my favorite and I receive compliments every time I wear it.
