How to Choose the Perfect Lab Diamond Necklace for Gifting

Imagine this: You surprise your loved one with a sparkling necklace that shines bright but costs less and comes without the worries of mining. That is the beauty of a lab diamond necklace. In 2025, lab grown diamonds already make up 20% of the diamond market (source: Gemological Institute of America). They give the same sparkle as mined diamonds, but at 30–50% less price.

This guide will help you step by step to choose the right necklace—one that matches your budget, the recipient’s style, and the meaning behind your gift.

Understand Lab Grown Diamonds

What Makes Them Special

Lab grown diamonds are made in high-tech labs using CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) methods. They are real diamonds, with the same hardness (10 on the Mohs scale) and sparkle as mined ones.

• Eco-friendly: No mining damage. Studies show lab diamonds cut carbon emissions by 90% compared to mined.

• Affordable: More sparkle for less money.

• Reliable: When certified by labs like IGI or GIA, you know you’re getting quality.

Action tip: Always check for certification before buying.

Differences from Mined Diamonds

To the naked eye, lab and mined diamonds look identical. Only experts with magnification can see small differences.

💡 Example: A 1-carat mined diamond costs around $6,000, but a 1-carat lab grown one costs about $2,500. That’s a huge saving—money you can use for a custom necklace design.

Pros of lab grown diamonds:

• Lower price.

• Faster to make (weeks, not millions of years).

• No conflict zones—fully ethical.

Set Your Budget Wisely
