Understanding Jewelry Profit Margins in 2026
Before comparing moissanite and lab-grown diamonds, it’s important to understand what drives gemstone profitability in a B2B environment.
Key Profit Margin Factors
- Raw material cost
- Manufacturing complexity
- Certification & grading costs
- Consumer price sensitivity
- Return and remake rates
- Customization potential
- Inventory risk
The gemstone that balances low acquisition cost with high perceived value consistently wins on margins.
What Is Moissanite? A Quick Business Overview
Moissanite is a lab-created gemstone known for its:
- Exceptional brilliance
- High durability (9.25 Mohs)
- Diamond-like appearance
- Affordable production cost
From a sourcing perspective, moissanite has transitioned from a niche stone to a mainstream alternative gemstone, especially in the U.S. market.
Why Moissanite Is Attractive for Jewelry Businesses

- Easy availability in multiple cuts and sizes
- Ideal for customization and private label collections
Many brands now work directly with a moissanite jewelry manufacturer to maintain control over quality and pricing.
What Are Lab-Grown Diamonds? A Commercial Perspective
Lab-grown diamonds are chemically and optically identical to mined diamonds but produced in controlled environments.
They appeal strongly to:
- Ethical buyers
- Bridal customers
- Luxury-conscious millennials and Gen Z
Why Lab-Grown Diamonds Are Commercially Viable
- Certified by IGI / GIA-equivalent labs
- Premium perception compared to alternatives
- Accepted widely in engagement and bridal jewelry
- Strong storytelling around sustainability
Brands sourcing from a lab grown diamond jewelry manufacturer gain access to consistent quality without mining volatility.

| Lab-Grown Diamond Jewelry | 55–70% |

- Engagement rings
- Fashion pendants
- Stackable rings
Lab-Grown Customization

Moissanite

Lab-Grown Diamonds
