When shopping for a diamond engagement ring, one of the biggest decisions is choosing between lab-grown diamonds and natural diamonds. Both options offer stunning brilliance, durability, and timeless elegance—but there are key differences in origin, price, sustainability, and value.

In this guide, we’ll break down the difference between lab-grown and natural diamonds, helping you decide which one is right for you.

What Are Lab-Grown Diamonds?

Lab-grown diamonds (also known as lab-created diamonds or man-made diamonds) are real diamonds created in controlled laboratory environments using advanced technology. They have the same physical, chemical, and optical properties as natural diamonds.

Key Features of Lab-Grown Diamonds:

  • 100% real diamonds

  • GIA or IGI certified

  • Created using High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD)

  • More affordable (typically 30–50% less than mined diamonds)

 

What Are Natural Diamonds?

Natural diamonds are formed deep within the Earth over billions of years. They are mined from natural sources and valued for their rarity and geological history.

Key Features of Natural Diamonds:

  • Earth-mined and naturally formed

  • Each diamond is unique

  • Considered more traditional and prestigious

  • Often holds higher resale value

Which One Should You Buy?

It depends on what matters most to you:

Choose Lab-Grown Diamonds if:

  • You want a larger diamond at a lower price

  • You prefer eco-friendly and ethical options

  • You’re buying a lab diamond engagement ring for value and brilliance

Choose Natural Diamonds if:

  • You value rarity and tradition

  • You're looking for a higher resale value

  • You want to own a diamond with a natural origin
