Best Shapes for Loose Diamonds: Round, Princess, Oval & More

Before we dive into shapes and cuts, let’s get this straight: Loose Lab Grown Diamonds are exactly what they sound like - diamonds that haven’t been set in jewelry yet. Think of them as blank canvases. They give you total freedom to design rings, earrings, or custom pieces that feel 100% you.

And when we say lab grown, we mean diamonds that are real, just ethically created in high-tech labs, not dug up from the earth. No blood, no baggage, just pure, brilliant sparkle.

If you’re eyeing loose lab grown diamonds, now’s the time to get creative with your cut.

Why Cut Quality Really Matters

You could have the best shape in the world - but if the cut’s trash? It won’t sparkle right.

Cut quality affects how your loose lab-grown diamond interacts with light. A well-cut diamond will:

• Look brighter
  
  
• Hide inclusions better
  
  
• Feel more luxurious (even at a smaller carat size)
  
  

Pro tip: Even a slightly better cut can make a smaller diamond look way bigger. So never compromise here, especially if you're comparing round vs oval lab diamonds or other shapes.
