Loose Diamonds

Choose your diamond. Make it yours.

Every diamond tells a different story — and no two are exactly alike. Our loose diamond collection lets you browse individually certified lab-grown diamonds and choose the exact stone that's right for you, whether you're designing a custom engagement ring, replacing a stone, or simply want to own a certified diamond on its own terms.

Why choose a loose diamond?

Full transparency. Every diamond in this collection is IGI-certified, with the certificate number listed on the product page so you can verify every detail independently.

Complete control. Compare shape, carat, color, clarity, and cut side by side, and choose based on what matters most to you — whether that's size, brilliance, or budget.

Build something personal. Pair your chosen diamond with one of our ring settings to create a piece that's entirely your own. (Coming soon: our online ring builder — for now, message our team and we'll help you put it together.)

Understanding the 4Cs

• Carat — the diamond's weight, not its size alone. Two diamonds of the same carat weight can look different sizes depending on cut.
• Cut — how well the diamond is proportioned and faceted, which determines how much it sparkles.
• Color — graded on a scale from colorless to faintly tinted. Most buyers can't detect a difference until several grades apart.
• Clarity — the presence of natural internal or surface characteristics, most of which are invisible to the naked eye.
