Choosing a diamond shape is about balance and personality. Round Brilliant cuts offer maximum fire and a timeless look, while elongated cuts like Oval, Emerald, and Pear are trending in 2026 for their ability to make the fingers appear longer and more slender. If you want a modern, "chunky" aesthetic, consider a Radiant or Cushion cut set in a bold 18K gold band.

Physically, chemically, and optically, they are identical. The only difference is their origin. At Sol et Terre, we specialize in sustainable luxury, offering certified lab-grown diamonds that allow you to invest in higher color and clarity grades—often $40-60\%$ more value for your budget—without the environmental impact of traditional mining.

The most reliable way is to borrow a ring they already wear on their ring finger and trace the inside diameter on paper. If you’re unsure, our Perfect Ring Guarantee is the ultimate safety net: propose with one of our signature designs and return together later to ensure a perfect fit and final design. Most of our rings also include one complimentary resizing as part of our lifetime service.

Yes, this is a Sol et Terre signature. We can source specific numerical carat weights to commemorate your story—such as a 1.22ct diamond for a December 22nd anniversary. This "Hidden Meaning" approach transforms a technical specification into a sentimental milestone, making your custom engagement ring truly one-of-a-kind.
