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/papers that come with it.
What we do NOT do (yet), 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. We do not claim otherwise anywhere.
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 a ticket queue.
What we're building (label this clearly as PLANNED, not current): a verification partner facility that will inspect every piece before it ships. Do NOT present this as already in place.
Where Solifacet differs
Collector Square provides an authoritative European luxury resale model, where in-house gemologists in Paris physically inspect every piece and issue a formal Certificate of Expertise with 14-day EU return rights. Because Collector Square takes physical consignment and operates a European showroom, transactions carry international shipping considerations for US buyers and focus heavily on signed luxury brand collections. Solifacet differs by operating as an unconsigned marketplace that holds no inventory, where the founder personally travels to inspect each piece and review its documentation in person before listing, providing direct founder-led service with shipping included in the price.
