A buyer searching for Bead is usually trying to stop a bad substitute. Jewelry is specified by the metal, the stone treatment, the plating thickness if it is plated, and the hallmark the market requires. The notes below are selection criteria for a Bead. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.
What has to be true of Bead
Jewelry is specified by the metal, the stone treatment, the plating thickness if it is plated, and the hallmark the market requires. For a Bead, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.
Bead is easy to confuse with Engagement Ring. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.
Numbers that change the quote
| Line | What to write for Bead |
|---|---|
| Size | Ring size, length, or the adjustment. |
| Hallmark | The mark required in the country of sale. |
| Skin contact | Nickel or other limits the market enforces. |
| Metal | Alloy and fineness, or the base metal under a plate. |
| Plating | Metal and thickness, if it is not solid. |
| Stone | Material, size, and whether it is treated. |
How to compare two offers
Lay both quotes for Bead on one sheet and line up size, hallmark, and skin contact. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Bead with a cheaper line that omitted size.
Documents worth having before the deposit
Ask for the fineness or plating specification in writing. The file should name Bead and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.
Failures that show up after delivery
- Leaving stone treatment undisclosed.
- Ignoring nickel rules.
- Describing plated goods as solid.
On a Bead, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.
A worked RFQ line
Use this shape, then replace the brackets with your duty: “Bead — State metal or plating, stone, size, and hallmark.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.
Where words like IP67 belong
Searches often add a constraint to Bead: IP67, or explosion-proof / ATEX. Keep those on this page. IP67 is dust-tight plus a defined temporary immersion. It is not a rating for living underwater, and it says nothing about sunlight or salt. ATEX or IECEx is a certificate for a zone, a gas or dust group, and a temperature class. An IP rating does not grant it. Skip the mark if the site is not hazardous. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask
What should an RFQ for Bead include?
State metal or plating, stone, size, and hallmark.
Is a cheaper Bead the same part?
Only if size, hallmark, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Bead they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
