Turquoise Materials & Treatment Disclosure

This page explains how TaShi uses turquoise material and treatment terms. A material name, treatment status, geographic origin, and laboratory finding are separate facts, and each needs its own support.

What Genuine Turquoise Means

“Genuine turquoise” means the material is identified as turquoise rather than a look-alike material. The term does not, by itself, establish whether the turquoise is untreated, stabilized, dyed, filled, reconstructed, or from a particular mine or region.

TaShi uses a genuine-turquoise statement for a product only when the available evidence applies to that product, SKU, material, or documented batch. Product photographs and appearance alone are not treated as proof of material identity or treatment status.

Genuine Does Not Mean Untreated

Turquoise can be genuine and still have a treatment. “Natural” and “untreated” are also not interchangeable: a naturally formed mineral may have been stabilized, dyed, filled, or otherwise treated after it was mined. An untreated claim requires specific support for the treatment status; it is not inferred from the word “genuine,” from color, or from matrix patterns.

Turquoise Treatment Terms

Term What it means How TaShi discloses it
Untreated No treatment has been applied to alter color, fill surface-reaching features, or improve stability. Used only when the treatment status is specifically supported for the product or applicable material scope.
Stabilized Turquoise has been treated to improve stability or durability, often by reducing its porosity. Disclosed separately from material identity when applicable evidence supports stabilization.
Dyed Color has been added or altered with a dye. Named directly when dyeing is established for the applicable product, material, or sample.
Filled Surface-reaching features, voids, or porous areas have been filled. The filling material must be supported separately before it is named. Disclosed as filled when supported; TaShi does not identify a specific filler without corresponding evidence.
Dyed and Filled Both color treatment and filling have been identified. Both treatments are stated together when the evidence applies to the product or sample in question.
Reconstructed Turquoise fragments or powder have been bonded or pressed into a new material. It is not the same as one intact piece of turquoise. Disclosed as reconstructed when supported. It is not presented as untreated turquoise.
Treatment Not Independently Verified The evidence reviewed does not establish a specific treatment status. This statement does not mean the turquoise is untreated or treated. It means TaShi is not making either claim without adequate support.

TaShi’s Disclosure Principles

  • Material identity and treatment status are disclosed as separate facts.
  • Product-specific wording takes priority over broad collection or brand language.
  • If a treatment status is not established, TaShi does not substitute “untreated” or another favorable term.
  • Mine, regional, or raw-material origin is not claimed from appearance alone.
  • Care information is kept separate from material proof and does not establish authenticity or treatment status.

What Testing Evidence Can and Cannot Show

A report can support only the findings, sample, component, material, batch, and test scope stated in that report. Depending on the test, it may address material identity, a treatment, a metal marking, or composition. It does not automatically answer facts outside its stated scope.

A report for one sample does not automatically represent every unit, every color variation, an entire product series, or all TaShi jewelry. Before a report is used in a product disclosure, TaShi must be able to connect its scope to the relevant product, SKU, component, material, or batch.

How to Check a Specific Product

Review the product page’s materials, treatment disclosure, specifications, and close-up photographs. If a treatment statement is not shown, do not assume the turquoise is untreated. You may contact TaShi before purchasing to ask what product-specific information is currently available.
