Blue Nile offers both natural and lab-grown diamonds. Here's a breakdown of the differences:

Natural Diamonds

• Origin: Mined from the Earth, formed over billions of years under extreme heat and pressure.
• Characteristics: Each natural diamond is unique, with its own set of inclusions and imperfections.
• Price: Generally more expensive due to their rarity and the extensive mining process.

Lab-Grown Diamonds

• Origin: Created in a controlled laboratory environment using advanced technological processes like High-Pressure High-Temperature (HPHT) or Chemical Vapor Deposition (CVD).
• Characteristics: Chemically, physically, and optically identical to natural diamonds, but often have fewer inclusions due to the controlled production process.
• Price: Typically 20-40% cheaper than natural diamonds of comparable quality.

Blue Nile provides a wide selection of both natural and lab-grown diamonds, allowing customers to choose based on their preferences, budget, and values1.
