ENGINEERED COLOR · PRECISION CRYSTAL
From vivid boules to finished optical and watch components, Shanghai Xinkehui turns a target color into a repeatable, production-ready sapphire program.
*Final size depends on crystal growth, geometry and finishing route.

THE XINKEHUI DIFFERENCE
Shanghai Xinkehui New Materials Co., Ltd. is a technology-focused supplier of semiconductor and optical crystal materials. For colored sapphire, our team combines crystal material knowledge, precision processing and practical export coordination to help customers move from a visual reference to a repeatable part.
Reference samples, dopant direction and color-window approval are aligned before production.
Grinding, lapping, polishing, chamfering and non-standard machining in one coordinated route.
Clear milestones, inspection records and export-ready packing for predictable lead times.
WHERE COLOR BECOMES FUNCTION
Colored sapphire gives designers and engineers a hard, stable and visually distinctive platform for parts that need to perform and be seen.

Faceted stones and matched color lots for rings, pendants and statement pieces.

Color-tuned covers, bezels and decorative inserts with sapphire-grade scratch resistance.

Colored filters, windows and protective covers for optical, sensing and specialty equipment.

Non-standard geometries developed from drawings, samples or a performance brief.

02 · MATERIAL ADVANTAGE
Alumina single-crystal sapphire combines high hardness, chemical stability, optical clarity and a premium visual surface. Controlled coloration adds a design language without giving up the material advantages that make sapphire valuable.
Strong scratch resistance for exposed surfaces, jewelry and wearable components.
Suitable for demanding environments where ordinary glass or coated polymer can drift.
Color references, approved samples and batch checks keep a collection visually coherent.
03 · FROM BRIEF TO SHIPMENT
Every project is structured so engineering decisions happen early and production stays calm.
Color chip, drawing, sample photo, quantity and application.
We align on material route, tolerance, finish and approval sample.
Batch records, dimensional checks and visual consistency review.
Protective packing, documentation and delivery coordination.

05 · FAQ
Short answers for design, sourcing and engineering teams evaluating a colored sapphire program.
Blue, red, pink, yellow, purple, green and mixed-color programs are available. We confirm each target against an approved reference.
Yes. We review dopant direction, color window, geometry and optical requirements before proposing a development route.
Both. Options include boules, rods, slabs, blanks, faceted stones, watch parts, windows and non-standard CNC components.
Typical parts range from sub-millimeter details to 600 mm optical dimensions, subject to geometry and process route.
Approved references, batch records and visual or instrumental checks are used before shipment.
Yes. Sample geometry and color confirmation are recommended before pilot or repeat production.
Lead time depends on color, geometry and quantity. Stock-supported parts move fastest; custom development is scheduled after technical review.
