The stone in front of you is probably a diamond. Proving it is not moissanite, CZ, white sapphire or zircon takes a reading, not a guess — and the answer you write down should say what you actually established.
How a jeweler works a take-in
A labeled example workflow — this is the intended use, not a customer story.
Separate diamond from its look-alikes
Dispersion alone does most of the work before RI or SG: diamond 0.044, cubic zirconia 0.066, moissanite 0.104 — the simulants show more fire, not less. Worked per pair: vs moissanite, vs cubic zirconia, vs white sapphire, vs zircon.
Write down only what you established
The engine returns a ranked candidate set and the next test that separates it, in “candidates include” and “consistent with” language. That is deliberate: naming a stone on a take-in envelope is a commitment, and a hedged reading is the honest record of what a reading actually proves.
Keep the record with the job
The session saves with the observations, the candidates, photos, client name and the date — so the envelope, the repair ticket and the file all say the same thing three weeks later.
The pieces that matter for jewelers & bench
Separation guides
Worked property-based separations for the pairs that actually cross a counter — diamond simulants, ruby and spinel, jadeite and serpentine, natural versus synthetic.
Examination reports
PDF/HTML reports from any session — observations, candidates, photos, your examiner details. White-label on Team.
Loupewise for Teams
$49/month flat for the whole shop — shared sessions, role-based access, audit trail, branded reports.
Reference database
The property data behind the engine, published openly — check any reading against the full 132-species table.
Free to identify, Pro for the paperwork
Identification and the full candidate list are free. Simulant guidance, treatment checks and report export are Pro (7-day free trial). Team is $49/month flat for the whole shop — no per-seat fees.
Loupewise is a field identification and documentation tool — indicators and candidates, not certifications, and it does not appraise or value stones. For consequential stones, refer to an accredited laboratory. Read our full methodology.
Run the next one through it
Start the trial, work the next five take-ins, and see whether the record is worth keeping.
