How verification works at Solifacet
Before a piece lists, the founder personally goes to the seller, inspects the piece in person — it exists, it matches its description, its condition is as stated — and checks the certification and papers that come with it.
What Solifacet does not do, stated plainly: melee diamonds and small accent stones are not individually lab-inspected. Inspecting each one costs more than the margin on the piece, so the industry standard is not to verify those individually. Solifacet does not claim otherwise.
If a piece turns out not to be as described, Solifacet handles it personally, case by case, and makes it right — including covering costs out of pocket when the situation warrants it. Customer service is founder-led, not an automated ticket queue.
What Solifacet Is Building (Planned): a verification partner facility that will inspect every piece before it ships.

If you want to BUY verified fine jewelry from vetted independent dealers, Solifacet provides a dedicated consumer marketplace with founder in-person inspection on every piece.
