ÊTRUNE University
Learn before you commit.
A standing reference on loose stones, written by the gemologists who grade the inventory.
What it is
Not a blog. A reference.
A short, current curriculum on loose gemstones — what a certificate says, what it hides, and what to ask before you spend.
Vocabulary
Read the report first
GIA, AGL, GRS, Gübelin — which fields actually move price, and how to verify them.
Treatments
Disclosed, accepted, rejected
Heat on corundum, oil on emeralds, irradiation on topaz. The line we hold.
Why
Educated buyers stay buyers.
Most jewellers sell you the certificate and stop talking. We don't — the cost of educating you is lower than the cost of a regret.
For whom
Couples · Collectors · Trade
The reading list is the same — only the depth varies.
ÊTRUNE University
Read first. Buy with intent.
Browse the shelf with the same vocabulary the trade uses — and the confidence to ask harder questions.
