Manufactured Diamonds: Market Trends, Growth, and Jewelry Sector Outlook (2025 Update)

1. What Are Manufactured Diamonds?

Manufactured diamonds—also known as lab created diamonds, lab cultured diamonds, or lab fabricated diamonds—are produced in controlled laboratory environments using advanced technological methods. These diamonds replicate the chemical composition, crystal structure, and optical properties of natural diamonds, offering an ethical and sustainable alternative to traditional mined stones.

With rising global demand for eco-friendly and affordable luxury, manufactured diamonds are gaining rapid popularity across jewelry applications—particularly in engagement rings and high-end fashion accessories.

2. Market Outlook: Set to Reach USD 21.78 Billion by 2030

The global synthetic diamond market for jewelry is projected to grow from USD 13.03 billion in 2023 to USD 21.78 billion by 2030, at a CAGR of 7.62% during the forecast period.

Key drivers include:

• Technological advancements in HPHT and CVD production processes

• Increased consumer awareness of ethical and environmental concerns

• Competitive pricing vs. natural diamonds, offering accessible luxury

3. Key Market Segments

a. By Application: Jewelry Leads the Market
