When Selena Gomez hard-launched her engagement to music producer Benny Blanco with a glowing Instagram post in December 2024, the internet went into a frenzy. And while the couple’s adorable moments since then have kept fans captivated, it was Gomez’s engagement ring that truly stole the show.
The six-carat marquise-cut diamond, estimated to cost more than $200,000 according to People Magazine, has already sparked a surge of interest in this vintage-inspired shape. And with the star recently spotted celebrating a bachelorette trip in Cabo, the countdown to her wedding has officially begun.
But here’s the good news: you don’t need a celebrity budget to get the Selena Gomez engagement ring look. At Ethica Diamonds, we specialise in creating stunning lab-grown marquise engagement rings - offering all the brilliance and beauty of Selena’s ring, with the added benefit of being responsibly made and all in Cornwall.
Why the Marquise Diamond Engagement Ring Is Trending Again
The marquise diamond has a fascinating history. Its elongated, boat-like silhouette was first commissioned in the 18th century by King Louis XV of France, who wanted a diamond cut to resemble the smile of his mistress. Centuries later, the marquise cut is making a strong comeback - sleek, flattering on the hand, and radiating vintage glamour with a modern twist.
Selena Gomez’s ring is proof that the marquise is having a revival. Its distinctive shape elongates the finger and maximises sparkle, making it a bold yet elegant choice for a bride who isn’t afraid to stand out.
