How to Buy an Engagement Ring in a Few Simple Steps
From diamond cut to setting and size, our engagement ring guide makes it easy to find the perfect ring — one designed to reflect your love and last a lifetime.

1. The 4C's
Every diamond, like a human fingerprint, possesses its own unique identity. The 4Cs — cut, color, clarity, and carat weight are the globally recognized standards used to evaluate diamond quality.
Understanding these characteristics is essential when selecting the perfect stone, and our Diamond Guide is here to help you navigate each one with clarity and confidence.

2. Ring Setting
A ring’s setting is more than just a design detail — it enhances the diamond’s beauty, secures the stone, and defines the overall character of the piece. From timeless solitaires to intricate halo and pavé designs, each setting tells a different story.
Explore our Ring Setting Guide to discover the style that best reflects your vision of forever.
