Product Specification

Lab-Grown Orange Sapphire Rough Material

Our Lab-Grown Orange Sapphire Rough Material is a synthetic corundum crystal developed for gemstone cutting, jewelry manufacturing, and custom colored gemstone applications. With its warm orange tone, excellent hardness, high durability, and good optical properties, it provides a consistent alternative material for customers looking for orange sapphire with controlled color and stable quality.

Synthetic sapphire has the same fundamental chemical composition and crystal structure as natural corundum, while laboratory growth allows better control over crystal size, color, and material availability. Synthetic corundum can be produced using different crystal-growth technologies, including flame fusion, Czochralski, and flux growth.

The orange color of sapphire can be associated with specific trace elements and color-producing defects within the corundum crystal structure. GIA research has documented orange synthetic sapphire produced through laboratory crystal-growth processes, including Czochralski-grown and flux-grown materials.

Applications

Our lab-grown orange sapphire material can be supplied as rough or semi-finished material for:

• Jewelry gemstones
• Custom-cut orange sapphire
• Rings, pendants and earrings
• Decorative gemstones
• Watch and luxury accessory applications
• Gemstone prototypes
• Jewelry design and development
• Gemological research and educational purposes

Custom Orange Sapphire Material

We can provide custom-sized lab-grown orange sapphire materials according to the customer's cutting and processing requirements. Depending on the intended application, we can discuss crystal size, thickness, color, transparency, surface condition and subsequent cutting requirements.

For customers purchasing material for gemstone production, supplying rough material instead of finished stones provides greater flexibility in selecting the final shape, size and faceting design.

Why Choose Lab-Grown Orange Sapphire?

Compared with naturally sourced gemstones, laboratory-grown sapphire offers a more controllable material source and can be produced in different colors and forms. Synthetic sapphire has been commercially produced for more than a century, and synthetic corundum is available in a wide range of colors, including ruby, blue, yellow, pink and orange.

For jewelry manufacturers and gemstone processors, lab-grown orange sapphire can be an attractive material when consistent color, predictable availability and customizable dimensions are important.

FAQ

Q1: Is this orange sapphire natural or lab-grown?
A: This product is lab-grown synthetic sapphire, also known as synthetic corundum. It is manufactured through controlled laboratory crystal-growth processes.

Q2: What is the chemical composition of orange sapphire?
A: Sapphire is a variety of corundum with the chemical composition Al₂O₃. Different trace elements and crystal defects can produce different colors.

Q3: Can the orange sapphire be cut into gemstones?
A: Yes. The material can be cut, faceted and polished into gemstones for jewelry and decorative applications.
