Lab Diamonds

Q: Does applying with Affirm affect my credit score?

Prequalifying uses a soft credit check, which does not affect your score. If you proceed with a loan, Affirm may perform a hard credit check at that point.

Q: What if I'm not approved?

Affirm's approval is based on several factors. If you're not approved for one plan, you may still qualify for a shorter term or smaller amount. You can also contact Affirm directly for details.

Q: Can I use Affirm with a discount code or trade-up credit?

Yes. Apply your discount or trade-up credit first, and finance the remaining balance through Affirm.

Q: What happens if I return a financed purchase?

Once we process your return, Affirm cancels the loan. Any payments already made are refunded to you. The process typically takes 5–10 business days.

Q: Is there a minimum or maximum purchase amount for financing?

Affirm sets its own minimums and maximums. Most Diamondaire purchases fall well within their range. You'll see financing availability confirmed at checkout.

Q: Can I finance a custom Ring Builder order?

Yes. Affirm is available at checkout for any order on our site, including custom ring builds.

The Diamond Standard

Lab Grown. Identical. Certified.

The same crystal structure, the same fire, the same independent grading — grown in a lab instead of pulled from the earth.

What Is a Lab-Grown Diamond?

A lab-grown diamond is a real diamond. Not a simulant, not cubic zirconia, not moissanite — a diamond with the same carbon crystal structure, the same optical properties, and the same hardness as any stone pulled from the earth.

The difference is origin. Instead of forming over billions of years underground, a lab-grown diamond is created in a controlled environment in a matter of weeks. The result is chemically, physically, and visually identical to a mined stone. Even trained gemologists cannot tell the difference without specialized equipment.

Every Diamondaire diamond ships with an independent IGI certificate confirming its cut, color, clarity, and carat weight — the same grading standards applied to mined diamonds worldwide.

Lab vs. Mined

	Lab-Grown	Mined
Composition	Pure carbon crystal	Pure carbon crystal
Hardness	10 (Mohs scale)	10 (Mohs scale)
Brilliance & fire	Identical	Identical
Certification	IGI / GIA graded	IGI / GIA graded
Origin	Controlled laboratory	Earth extraction
Environmental impact	Significantly lower	Land disruption, water use, carbon-intensive
Traceability	Fully traceable	Varies widely
Price	40–60% less at equivalent grade	Higher due to supply chain and markup

How They're Made

HPHT (High Pressure, High Temperature) Replicates the conditions deep within the earth. A small diamond seed is placed in a press with carbon material, then subjected to extreme heat (around 1,500°C) and pressure. The carbon crystallizes around the seed, atom by atom, forming a rough diamond over several weeks.

CVD (Chemical Vapor Deposition) A diamond seed is placed inside a sealed chamber filled with carbon-rich gas. The gas is heated until it breaks down, and carbon atoms rain onto the seed, building the diamond layer by layer. CVD allows for precise control of the growing conditions and produces exceptionally clean stones.

Both methods yield genuine diamonds. The method used does not affect the quality, durability, or brilliance of the finished stone.

The 4Cs Still Apply

Every lab-grown diamond is graded on the same four criteria as a mined stone: cut, color, clarity, and carat weight. These determine how your diamond looks on your hand, how it catches the light, and how it's priced.
