01
THE XINKEHUI DIFFERENCE
One material partner from color brief to stable delivery.
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.
01Custom color programs
Reference samples, dopant direction and color-window approval are aligned before production.
02Integrated finishing
Grinding, lapping, polishing, chamfering and non-standard machining in one coordinated route.
03Reliable handoff
Clear milestones, inspection records and export-ready packing for predictable lead times.
WHERE COLOR BECOMES FUNCTION
Designed for the moments
people remember.
Colored sapphire gives designers and engineers a hard, stable and visually distinctive platform for parts that need to perform and be seen.
02
Watch & wearable parts
Color-tuned covers, bezels and decorative inserts with sapphire-grade scratch resistance.
03
Optical & sensor windows
Colored filters, windows and protective covers for optical, sensing and specialty equipment.
04
Custom crystal components
Non-standard geometries developed from drawings, samples or a performance brief.
Color, geometry and finish are treated as one engineering brief.
02 · MATERIAL ADVANTAGE
Color that stays beautiful.
Performance that stays useful.
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.
01
High hardness · Mohs 9
Strong scratch resistance for exposed surfaces, jewelry and wearable components.
02
Thermal & chemical stability
Suitable for demanding environments where ordinary glass or coated polymer can drift.
03
Repeatable visual language
Color references, approved samples and batch checks keep a collection visually coherent.
03 · FROM BRIEF TO SHIPMENT
A clear route for custom work.
Every project is structured so engineering decisions happen early and production stays calm.
01
Share the target
Color chip, drawing, sample photo, quantity and application.
02
Review & sample
We align on material route, tolerance, finish and approval sample.
03
Produce & inspect
Batch records, dimensional checks and visual consistency review.
04
Pack & deliver
Protective packing, documentation and delivery coordination.

05 · FAQ
Useful answers before
you request a quote.
Short answers for design, sourcing and engineering teams evaluating a colored sapphire program.
What colors of sapphire can you supply?+
Blue, red, pink, yellow, purple, green and mixed-color programs are available. We confirm each target against an approved reference.
Can you develop a custom color?+
Yes. We review dopant direction, color window, geometry and optical requirements before proposing a development route.
Do you supply rough boules or finished parts?+
Both. Options include boules, rods, slabs, blanks, faceted stones, watch parts, windows and non-standard CNC components.
What is the typical size range?+
Typical parts range from sub-millimeter details to 600 mm optical dimensions, subject to geometry and process route.
How do you control color consistency?+
Approved references, batch records and visual or instrumental checks are used before shipment.
Can you provide sample pieces first?+
Yes. Sample geometry and color confirmation are recommended before pilot or repeat production.
What is the lead time?+
Lead time depends on color, geometry and quantity. Stock-supported parts move fastest; custom development is scheduled after technical review.
How do I request a quotation?+
Send a color reference, drawing or sample photo, dimensions, quantity and target application through the form or WhatsApp.
