Why Lab-Grown

The same brilliance, lab-grown.

Chemically identical to mined diamonds

Same carbon crystal structure. Same hardness (10 on Mohs). Same refractive index. Same fire and scintillation. A trained gemologist cannot tell the difference under a loupe — only specialized lab equipment can.

Maximum size for your budget

Lab-grown diamonds typically cost 5–7× less per carat than the mined alternative with identical specs. That means a bigger stone, a higher clarity grade, or extra room in your budget for the setting.

Lab-grown, always disclosed

No mining. Each stone is grown in a controlled environment and listed with its grading report.

The only kind of diamond we sell

We've built our entire diamond inventory around lab-grown stones because they offer the best value and the same visual beauty as anything mined. Every Gallo engagement ring, every pendant, every tennis bracelet is lab-grown.

Diamond Education

The 4Cs, briefly.

Cut

How the diamond was shaped and faceted. The single biggest driver of sparkle. Read more →

Color

Graded D (colorless) to Z (light yellow). G–H is the value sweet spot. Read more →

Clarity

How visible the natural inclusions are. VS1–VS2 is eye-clean at most price points. Read more →

Carat

Weight, not size. Price scales nonlinearly — just under round numbers is best value. Read more →

Common Questions

Quick answers.

What is the difference between GIA and IGI certification?

Both grade the 4Cs and certify any treatments. GIA is the global gold standard for natural diamonds. IGI is the leader in lab-grown certification.

Are lab-grown diamonds real diamonds?

Yes — chemically, physically, and optically identical to natural diamonds. Same hardness (10 Mohs), same refractive index, same crystal structure. The only difference is origin.

Which diamond shape sparkles the most?

Round brilliant. It's engineered to maximize light return with 57–58 facets. Oval, cushion, and radiant follow closely. Step cuts (emerald, asscher) produce broader, more architectural flashes.

What carat size should I get?

National average for engagement rings is 1.0 to 1.5 carats. Hand size, finger length, and setting style all matter. We recommend trying several in person before committing.

Do you offer financing?

Yes — pay over time with Shop Pay Installments at checkout. Split your purchase into 4 interest-free payments, or choose monthly installments on larger orders. Seeing your options won't affect your credit score.
