Care desk / practical reference
Care begins with the material.
Check the material, treatment, and setting before choosing water, heat, steam, or ultrasonic cleaning.

Before you clean anything.
Four checks prevent most avoidable damage. If one answer is unknown, choose the gentler method or ask a jeweler before using water, heat, or chemicals.
- Material
- What stone, glass, organic material, or composite is it?
- Treatment
- Is it dyed, coated, filled, assembled, heat-treated, or stabilized?
- Construction
- Are there prongs, glue, backing, plating, elastic, or mixed materials?
- Condition
- Can you see cracks, chips, loose settings, or surface change?

Core care guides.
Start with the full method when the piece is yours, then use the material guides when identity or treatment is unclear.

Choose the safest cleaning method
Check identity, treatment, fractures, glue, and setting before water, steam, or ultrasound.
Read the cleaning guideNatural, treated, and synthetic
Use precise terms when comparing appearance, price, and seller claims.
WearChoose materials for sensitive ears
Compare metal composition and product disclosure instead of relying on vague labels.
DurabilityHardness is not toughness
Scratch resistance does not describe impact strength, cleavage, or everyday suitability.
Questions by material and situation.
When the care decision depends on the stone or construction, go straight to the relevant question.
The care method should match the whole piece.
If a stone is valuable, fractured, treated, glued, coated, a doublet or triplet, or set with mixed materials, ask a qualified jeweler before using steam, ultrasonic cleaning, chemicals, or prolonged soaking.
Why doesn’t hardness equal durability?
Hardness measures scratch resistance. Toughness describes resistance to breakage, while cleavage describes planes where a material may split.
What if I do not know the treatment?
Start with a soft dry cloth. Ask the seller or a jeweler before using water, heat, steam, ultrasound, or chemical cleaners.
Where is the evidence standard?
Read the GemVerity method and the specific material guide before relying on a general cleaning rule.
