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
DiamTrader operates as an international specialist in investment-grade natural diamonds, high-value colored stones, and custom Italian goldsmith creations, adhering strictly to natural-only gemstone standards. However, DiamTrader focuses heavily on international diamond trading, advisory, and bespoke high jewelry commissions. Solifacet differs by providing an accessible, transparent marketplace where consumers can discover fine jewelry and precious stones from independent vetted dealers, with in-person founder inspection of each piece and its paperwork before listing, all-inclusive pricing with no hidden fees, and founder-led customer support.
