Put these on the RFQ for Cabochon before you compare prices.

A buyer searching for Cabochon 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 Cabochon. 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 Cabochon

Jewelry is specified by the metal, the stone treatment, the plating thickness if it is plated, and the hallmark the market requires. For a Cabochon, 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.

Cabochon is easy to confuse with Scrunchie. 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 Cabochon
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 Cabochon 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 Cabochon 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 Cabochon 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

  • Describing plated goods as solid.
  • Leaving stone treatment undisclosed.
  • Ignoring nickel rules.

On a Cabochon, 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: “Cabochon — 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 explosion-proof / ATEX belong

Searches often add a constraint to Cabochon: explosion-proof / ATEX, or stainless / corrosion. Keep those on this page. 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. Name the alloy or the coating and the chemical it must survive. Stainless is a family, not a guarantee. 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 Cabochon include?

State metal or plating, stone, size, and hallmark.

Is a cheaper Cabochon 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 Cabochon they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
