Each glass and crystal material features unique structural properties, thickness availability, and processing compatibility. Every variant serves distinct production techniques and product positioning, with no hierarchical quality difference between materials.
1. K9 Crystal
K9 crystal is a premium fully transparent optical crystal with excellent light transmittance and consistent internal structure. To meet diverse custom market demands, K9 crystal is stocked in complete thickness ranges from 10MM to 100MM. It delivers exceptional performance for standard 2D surface engraving and high-precision 3D internal laser carving, producing sharp, clean, and highly detailed engraved patterns.
In addition to clear transparent blanks, K9 crystal is offered in 7 standard color variations. Its versatile color options and full thickness coverage make it suitable for nearly all custom crystal applications. Over 90% of customized crystal orders utilize K9 crystal, especially all crystal products with thickness above 20MM.
2. Jade Glass
Jade Glass is a high-clarity transparent material defined by its distinctive natural jade-green edge tone. Featuring stable and unique color aesthetics, this material is widely adopted for thin glass medals and decorative crystal blanks, with production limited to thicknesses under 20MM.
Due to its inherent structural characteristics, Jade Glass thinner than 20MM cannot undergo 3D internal engraving. It is fully compatible with all conventional 2D surface engraving techniques for decorative and commemorative productions.
3. White Glass
White Glass is a classic fully transparent glass material with slightly higher transparency than Jade Glass. It is not entirely colorless, presenting a subtle natural blue tint when viewed from the side.
This material maintains a similar cost level to Jade Glass and is likewise restricted to blank thickness below 20MM. It supports professional 2D surface engraving but does not support 3D internal engraving processes.
Both Jade Glass and White Glass feature lower production costs compared with K9 crystal. Featuring flat double-sided surfaces that require no complex polishing or grinding work, these two materials enable faster processing and lower manufacturing expenses. They are ideal for budget-friendly promotional medals, trophies, and custom pieces that require surface UV printing.

We are a professional B2B wholesale supplier specializing in standardized K9 crystal blanks. We provide full-thickness clear and 7-color custom K9 crystal blanks that perfectly support high-precision 2D and 3D laser engraving, catering to global manufacturers’ needs for premium custom crystal products.
