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.
Where Solifacet differs
Ada Diamonds operates as a high-end concierge service, curating only the top tier of lab-grown diamonds free from post-growth treatments or strain patterns, and setting them into bespoke custom mountings. Buyers wanting a white-glove custom design experience with private showroom appointments find an elite partner in Ada Diamonds. Solifacet provides a distinct experience: a curated marketplace where independent vetted jewelers offer ready pieces and rare stones that the founder physically verifies in person before listing.
