The sequence

  • Selection. We pick products readers actually ask about: bangles in common diameters, pendants under a set price, carved pieces with treatment claims, and vendors with a track record of shipping overseas.

  • Ordering. The editor places the order personally and logs the order date, quoted shipping window, carrier, tracking events and arrival day, so we can report real transit time rather than a stated estimate.

  • Arrival and packaging. We photograph the parcel before opening, note the box, pouch, padding, certificate and customs paperwork, and record any chipping, wax residue, odor or loose stringing.

  • Bench tests. Weigh on a 0.001 g scale, measure with calipers, inspect under 10x and 30x loupes with fiber-optic light, take refractive index on a flat polished surface, run hydrostatic specific gravity to 0.01, check long-wave and short-wave UV response, and use a dichroscope and Chelsea filter where they add information.

  • Treatment assessment. We state what our instruments support and what they do not. Refractive index and specific gravity can rule some imitations in or out; confirmed bleached-and-polymer-impregnated or dyed material usually needs a laboratory memo, so we say when a claim remains unconfirmed.

  • Wear testing. Pendants are worn 14 days and bangles 30 days by a named editor, with rotation notes, hairline inspection and exposure to hand soap, sunscreen and daily knocks.

  • Price check. On scoring day we record the current asking price at three retailers and note shipping cost, duties and return terms.

  • Scoring and comparison. Five categories, each out of 5, weighted into an overall score written as X / 5, followed by a comparison table against two or three close alternatives we have also tested.

What we do not claim

Our bench readings are not a gemological certificate and not an appraisal. Where a purchase depends on provenance or a treatment guarantee, we tell readers to ask the vendor for a laboratory memo from a recognized lab.

Scope of the findings

Each reading identifies the piece and applicable test conditions. Wear periods concern the named sample; price comparisons identify their capture date and do not guarantee a later sale price.
