# Nordstrom Gemstone Details Field Guide

> Describes any details of the gemstones present in the product that are not captured in other structured gemstone attributes.

**Gemstone Details** is an optional Nordstrom Marketplace attribute for jewelry with stones. It captures the stone facts that do not fit into Nordstrom's structured gemstone attributes: cut, carat weight, clarity or color grade, origin, treatment, setting style, whether the stone is natural, lab-grown or simulated. Nordstrom shows the value on the product page, where a shopper spending on fine jewelry reads it closely.

The field appears once the listing has a Nordstrom jewelry category that uses it. Nordstrom validates only the length.

## The rules

| Rule | Value |
| --- | --- |
| Required | No |
| Level | Parent listing, shared by every size |
| Maximum length | 5000 characters |
| Content | Stone facts not already captured in structured gemstone attributes |

State only what your product data supports. Carat weight, grades and origin are claims a shopper can dispute, so a missing fact is better than an approximate one. Write the total carat weight with its abbreviation ("0.50 ct. t.w."), name treatments ("heat-treated sapphire") and say when a stone is lab-created or simulated. Metal content belongs in [Material Details](/marketplaces/nordstrom/fields/material-details), and dimensions in [Measurement Details](/marketplaces/nordstrom/fields/measurement-details).

## Examples

| Value | Verdict | Reason |
| --- | --- | --- |
| Round brilliant lab-grown diamond, 1.00 ct., G color, VS1 clarity, prong set | Good | Cut, weight, grades, origin and setting |
| Cabochon-cut natural turquoise, stabilized, bezel set in 14k gold | Good | Names the treatment and the setting |
| Sparkling stones that catch the light | Weak | No facts |
| 14k yellow gold | Weak | Metal goes in Material Details |
| Ring size 7 | Weak | Size is a variant attribute |

## Common mistakes

- Calling a cubic zirconia or crystal a "diamond" or leaving out that a stone is simulated.
- Rounding carat weights up or quoting a grade the supplier did not certify.
- Repeating the stone type when it is already selected in a structured gemstone attribute; use this field for what those attributes cannot hold.
- Describing the metal or chain instead of the stones.

## How Osello fills this field

Osello treats Gemstone Details as an optional parent-level text field with a 5000-character cap. It reads the product description, specification bullets and metafields for stone type, cut, carat weight, grades, origin, treatment and setting, and writes them as one short block without marketing language. If the source data says nothing about the stones, the field stays blank. Every size of the piece shares the value.

## Frequently asked questions

### Is Gemstone Details required on Nordstrom Marketplace?

No. It is optional and appears only for jewelry categories. Fill it whenever you have verified stone facts, since shoppers compare them across listings.

### Should I repeat the stone type here if it is already a separate attribute?

No. Use Gemstone Details for cut, weight, grades, origin, treatment and setting, the facts the structured attributes do not capture.

### How do I describe a lab-grown or simulated stone?

Say so in the value ("lab-grown diamond", "simulated sapphire"). Leaving it out reads as a claim that the stone is natural.

### Does the metal go here too?

No. Put karat, plating and metal type in Material Details and keep this field for the stones.
