Quick Answer
On a single MYNSU test piece, check five things: the 925 stamp on the metal, how the center stone reads on a tester, how securely every stone is set, how the clasp moves, and what ships inside the box. Order it through the Partner Portal at your normal partner price — there is no minimum, so testing one piece first is the standard way to start, not a workaround.
Why Test One Piece Before a Larger Order
Stock orders placed at partner price are a final sale: once a piece is confirmed correct, you cannot send it back because a style did not sell. Ordering a single piece first, at the same account price as any other quantity, lets you inspect the real piece against the listing before you decide whether to reorder it at all.
A few practical reasons partners run this check on each new style, even one picked from our bestsellers:
- Catalog photos and a physical piece can read slightly differently under your own lighting and camera setup
- A style's actual size, weight and stone placement are easier to judge in hand than from a product page
- Any question about stamping, stone type or finish is faster to answer by looking at the piece than by asking us
- Because partner orders are final sale, confirming the piece before you commit is the only inspection point you get

Check the Metal Stamp and Finish
Every sterling silver piece in the MYNSU catalog is stamped S925 somewhere on the metal — inside a ring band, on the back of a pendant, or on an earring post or clasp. On your test piece, find the stamp, confirm it is legible, and compare the finish (polish, texture, plating color if the listing names one) against the product photos before you list the same style at scale.
- Locate the S925 stamp and check it is clear enough to photograph for your own listing if you want to show it
- Compare the actual plating color or finish to what the product page states, since gold-tone and silver-tone versions of the same design are listed separately
- Look for an even finish with no rough edges where the band, clasp or post was formed
Check the Stone on a Tester Before You Trust a Catalog Line
Center stones are moissanite, and accent stones are named on each product page as moissanite, cubic zirconia, or no stone at all, rather than one blanket claim for the whole catalog. A tester is a quick way to confirm you received the stone type the listing describes, before you reorder a style in volume or pass claims to your own customers.
Some thermal diamond testers read moissanite as diamond because the two materials conduct heat in a similar way; a dual tester or a tester built for moissanite tells the two apart reliably, and so does a professional gemological check. Moissanite is its own gemstone, not a diamond, whatever a basic thermal tester reports. Our full breakdown of how moissanite behaves on different testers is in our guide to moissanite and diamond testers.
- Use a dual or moissanite-specific tester rather than a basic thermal-only tester, since a thermal tester alone can misread the result
- Cross-check the accent stones against the product page's own wording — moissanite, cubic zirconia, or none — rather than assuming every stone in the catalog is the same material
- Check that a GRA certificate for the center stone is in the box, since that is what ships with the piece rather than a per-accent-stone certificate

Check the Setting, the Clasp and Any Moving Parts
A test piece is your one chance to handle the actual setting rather than a photo of it: gently check that every stone sits flush and does not rock in its prongs or bezel, that a cluster or pavé piece has no visibly loose stones, and that a clasp, hook or closure opens, closes and latches the way the listing implies before you reorder the style for your own customers.
- Press lightly around each prong or bezel edge and confirm no stone moves or feels loose
- Open and close a necklace clasp, earring back or bracelet closure a few times and check it latches securely each time
- On a multi-stone or cluster design, scan the whole piece rather than just the center stone, since smaller accent stones are the ones most likely to need a closer look
- Note anything you would want to mention in your own product description, such as a slightly stiff clasp or a particular setting style
Check the Packaging and What Ships Inside the Box
Dropship and stock orders ship in a plain, unbranded parcel by default: no invoice, no price slip and none of our contact details inside, and no logo of any kind on the packaging. On your test piece, confirm the parcel itself carries nothing that would identify MYNSU to your own customer, and check that the GRA certificate for the center stone is included as expected.
- Open the parcel the way your own customer would and confirm nothing inside names MYNSU or shows a price
- Confirm the GRA certificate for the center stone is in the box
- If you have arranged your own logo packaging for a style, confirm your logo prints or engraves the way the mockup showed before you commit to a larger run

What to Do If the Test Piece Arrives Wrong
If the piece is the wrong item, is missing a part, shows transit damage, or has a manufacturing fault, tell us within 3 calendar days of delivery — by email, the Returns form, or a Partner Portal message — with a short description and photos or a video, and we replace it or credit your account. This window is separate from the final-sale rule, which covers a correct piece you simply decide not to reorder.
- Photograph the issue (the stamp, the stone, the setting, or the packaging) as soon as you notice it
- Report it within 3 calendar days of delivery, not weeks later, so the issue is still easy to verify
- Keep the original packaging until the issue is resolved, in case we need to see how it arrived
Frequently Asked Questions
Can I really order just one piece before committing to wholesale quantities?
Yes. Stock styles in the Partner Portal have no minimum order: you can order a single piece at your partner price, the same price you would pay on a larger order, and reorder only the styles that test well and sell. There is no separate sample price or sample order.
What if I don't have a diamond or moissanite tester?
A tester helps confirm the stone type but is not the only check. You can still verify the 925 stamp, inspect the setting and clasp by hand, and compare the piece against the GRA certificate and the product page's own description of the stone before deciding whether to reorder.
Can I return the test piece if I simply don't like it?
No. Orders placed at partner price are a final sale, including a single test piece: once it arrives correct, it cannot be returned for a change of mind. That is exactly why the checks on this page matter before you decide to reorder a style in a larger run.
Is a test piece priced differently from a bulk order?
No. A single piece and a larger order of the same style are both priced at your partner price in the Partner Portal cart. Testing one piece first does not cost you a markup — it is simply the smallest quantity you can order of any stock style.
What should I do before I list the style at scale?
Confirm the stamp, stone, setting, clasp and packaging on your test piece match what you plan to say in your own listing, then photograph the piece yourself if you want images that match your store's style before placing a larger order for that style.
