Shipments are insured through the carrier, with tracking; shipping is paid by the buyer and included in the piece's price. | Handled by sellers using Mercari prepaid shipping labels or seller-arranged shipping; insurance limits depend on the selected carrier option. |
| Price transparency | The price you see is the price you pay, with no added buyer fees or hidden checkout surcharges. | Listing prices are displayed; marketplace buyer service fees, payment processing fees, shipping fees, and taxes are calculated and added at checkout. |
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
Mercari provides a quick, convenient mobile marketplace for everyday consumer secondhand goods with clear 3-day delivery confirmation windows. However, Mercari does not physically inspect jewelry, relies on digital photos for its optional authentication badge, and applies variable buyer and service fees at checkout. Solifacet differs by focusing exclusively on fine jewelry and precious stones, where all sellers are vetted, the price shown is the final price without added buyer fees, and the founder personally inspects each piece in person before it lists.
Questions & Answers
Solifacet vs Mercari — what's the difference?
Mercari is an open consumer marketplace with no pre-listing physical inspection, where authentication is based on digital photo review. Solifacet is a specialized fine jewelry marketplace where the founder personally travels to inspect the physical piece and review its paperwork before it lists.
What does 'verified' mean on Solifacet?
On Solifacet, verified means the founder has traveled to the seller, personally inspected the physical piece to ensure it exists, matches its description, and reflects its stated condition, and reviewed its accompanying certificates or documentation. It does not mean every melee diamond or tiny accent stone has undergone independent lab analysis, as those stones are not individually tested.
What is Solifacet's return policy?
Solifacet provides a 3-day inspection window following delivery for approved claims involving counterfeit items or material misrepresentation, supported by valid proof. Change-of-mind returns are not accepted, as purchase terms are confirmed in writing prior to payment.
Does Mercari physically inspect fine jewelry?
Mercari does not physically inspect fine jewelry. Its optional Mercari Authenticate badge relies on third-party specialists reviewing uploaded photographs of hallmarks and serial numbers.
