Natural Crystal
A naturally formed crystalline mineral, such as amethyst, clear quartz or rose quartz.
Natural origin must be verified before use.Material Transparency
Colored stones should not all be described as natural crystals. Every product should clearly state its material origin, material type, treatment status and natural variation information.
A naturally formed crystalline mineral, such as amethyst, clear quartz or rose quartz.
Natural origin must be verified before use.Naturally formed gem material used for jewelry, including materials that may not technically be crystalline.
Example: natural volcanic glass such as obsidian.Natural-origin material modified through heat, dyeing, stabilization, coating, impregnation or another enhancement.
The treatment method should be disclosed.Laboratory-created crystal or gemstone material manufactured to reproduce a specific appearance or material structure.
It must not be described as natural.Manufactured glass used for decorative beads, stones and jewelry components.
It should be clearly identified as glass.Material made from bonded, reconstructed, assembled or mixed natural and manufactured components.
The composition should be clearly explained.Recommended Product Data

Crystal Reference
Color, texture, treatment and batch consistency vary by material. Final product information should always be confirmed according to the actual item and production batch.
Quality Evaluation
Terms such as A, AA, AAA or 5A are not universal industry standards. When grade letters are used, the inspection criteria behind each grade should also be clearly defined.
Hue, saturation, tone, distribution and overall color uniformity.
Transparency, translucency, internal veils and visible inclusions.
Scratches, pits, chips, abrasions, residue and visible damage.
Roundness, faceting, symmetry, cutting accuracy and shape consistency.
Bead diameter, product dimensions and agreed size tolerance.
Hole diameter, position, alignment, chipping and blocked holes.
Surface luster, smoothness, edge finishing and polishing consistency.
Color, size, shape, finish and appearance within the confirmed batch.
Bead Specifications
Exact measurements and tolerances should be confirmed according to the actual SKU, production process and approved order requirements. No universal tolerance should be applied to every material.
| Specification | Information to Provide | Buyer Verification Point |
|---|---|---|
| Bead Diameter | Actual nominal bead size | Confirm measurement method and size range |
| Size Tolerance | Declared according to the actual SKU | Do not assume one tolerance for all materials |
| Hole Diameter | Specified hole size or accepted range | Confirm compatibility with cord, wire or findings |
| Strand Length | Approximate or specified total strand length | Confirm whether clasp or extension is included |
| Approximate Bead Count | Estimated count based on size and strand length | Natural size variation may affect final count |
| Shape | Round, faceted, irregular, carved or custom shape | Confirm acceptable shape consistency |
| Finish | Polished, matte, faceted, coated or other finish | Confirm surface appearance and edge quality |
| Color Range | Approved tone or batch color range | Request batch photos for strict color matching |
| Treatment | None, heated, dyed, stabilized, coated or other | Use actual treatment disclosure |
| Unit of Sale | Per strand, piece, pack, weight or other unit | Confirm order and quotation calculation method |
Product pages and quotations should display actual values wherever available. Missing measurements should be confirmed before ordering.
Natural Material Notice
Natural crystal products are not visually identical. Buyers should understand the accepted natural range while suppliers should control each batch according to the approved order standard.
Acceptable Natural Variation
Potential Quality Defect
Inspection & Documentation
Inspection items and supporting documents depend on the material, product type, order quantity and confirmed customer requirements.
Confirm the declared material name, type and known treatment.
Review color range, pattern, size and overall batch consistency.
Measure bead diameter or relevant product dimensions.
Check hole size, position, alignment and visible damage.
Check polish, scratches, chips, pits, residue and edge condition.
Confirm whether a relevant certificate is available for the item.
Provide batch or packing photographs when agreed for the order.
Crystal Care
Different crystal and gemstone materials have different hardness, stability and treatment characteristics. Care instructions should be adjusted according to the actual material.
Protect beads and stones from drops, knocks and pressure that may cause chips, cracks or breakage.
Keep crystal products away from perfume, cosmetics, cleaning agents and other chemical substances.
Different materials have different hardness levels and should not automatically be cleaned or stored in the same way.
Avoid prolonged strong sunlight or soaking unless the specific material and treatment are confirmed as suitable.
Use separate pouches, compartments or protective packaging to reduce scratching and contact damage.
