It is not enough to know that there is diamond inventory; you have to know the inventory of a particular variety of diamond. Depending on the business, a diamond can be identified by its shape, carat weight, measurements, colour, clarity, certificate or report number, supplier, location, status and price.
Diamond inventory management software makes it easier for jewellery businesses to organise these attributes, make them searchable in the inventory records, and track the movement of every stone from purchase, storage, memo, manufacturing, to sale/transfer. A diamond trader, for example, might be interested in loose and certified stones while a jewellery manufacturer might be interested in stones from the stone issue through production to finished jewellery.
The proper system should thus respond more than “How many diamonds do we have?” Should help to answer the question of which diamonds, what characteristics, where they are, what status they have, and what transaction changed their status.
What Is Diamond Inventory Management Software?
Diamond inventory management software is a special type of software designed to record, search, track, and report on diamond stocks based on parameters that are relevant to the diamond trading industry.
Conventional inventory may only need to identify a product by SKU and quantity, but with diamond inventory, it might need detailed stone-level information. For instance, GIA provides descriptions of diamond quality using the 4Cs (colour, clarity, cut, and carat weight) and can also determine diamond shape, measurements, and report number.
A helpful inventory record for a diamond business could contain:
- A stone or stock number that is unique.
- Shape and cutting style
- Carat weight
- Measurements
- Colour
- Clarity
- Cut, where applicable
- Polish and symmetry (where appropriate).
- Fluorescence, where relevant
- Natural or lab-made classification (if necessary)
- Cert>/Grade Report #
- Supplier or source
- Purchase information
- The price at which the item is sold or the basis on which it is sold.
- Location
- Stock status
- The status of the memo, consignment, or transaction.
The fields should match the business, not be a laundry list of data that no one cares to keep up.
Why Diamond Businesses Need More Than Basic Stock Tracking
For a basic stock system, it would display the number of diamonds in stock, which is 125 in this case. While that is helpful, it’s not enough for a trader looking for a specific shape, size, colour and clarity.
For instance, if a car owner wants a round diamond in the carat range, colour, clarity, and a recognised laboratory report, with a specific report. If the inventory system doesn’t have the ability to search those attributes together, then staff may need to check spreadsheets, certificates, and physical stock.
When a business is managing inventory for diamonds, the importance of diamond inventory management is magnified when:
- Loose diamonds
- Certified diamonds
- Diamond parcels
- Diamonds issued to jewellery production
- Diamonds received back from production
- This is a message for others to read; a letter to someone.
- Several warehouses/branches.
- A piece of diamond jewellery with a single stone or diamond.
- High-value stones that need thorough documentation.
The primary rule is that attributes should be made visible and transactions should be made traceable.
Which Diamond Attributes Should You Track?
1. Shape and Cutting Style
Shape refers to the outline of a diamond, which can be round, princess, emerald, oval, pear, or marquise. GIA differentiates shape and style of cut from the overall cut assessment.
A good inventory system needs to enable employees to search and filter by shape and not just in a free text description.
2. Carat Weight and Size
The weight of a diamond is measured in metric carats, which is equivalent to 0.2 grams. Additionally, GIA points out that weight can be measured to an extremely fine degree before reporting to the appropriate degree of precision.
Some businesses may also require measurements like length, width, and depth for inventory. Carat weight is not sufficient to make an inventory description for two diamonds with the same weight but different proportions and looks.
3. Colour
Colour grading is a term used for regular D-to-Z coloured diamonds and refers to the strength of the colour. It is important to record the actual grade on the diamond rather than giving an imprecise description like “white” or “good colour” because this will be maintained through the diamond’s inventory.
Additional information might be required for fancy-colour diamonds due to the way GIA assigns a colour grade to fancy-colour diamonds, including information on hue, tone and saturation.
4. Clarity
Clarity is a relative term to describe inclusions and blemishes. GIA’s clarity scale covers Flawless, Internally Flawless, through VVS, VS, SI and Included.
This is why clarity is a useful attribute for searchable inventory. It shouldn’t be the buyer’s responsibility to search through all the diamond records for VS1 stones.
5. Cut, Polish, Symmetry and Other Grading Information
Cut does not equal shape. The cut of a diamond references the shape and size of the facets and the proportions of the diamond relative to its overall appearance and light-performing qualities.
Other grading details such as polish, symmetry, fluorescence, proportions, etc. may also be needed depending on the business.
What is important is to make sure that different fields are used to describe the stone and not its commercial status.
6. Certificates and Report Numbers
Another layer of traceability is certified diamonds. A grading report can give a third-party record of the characteristics, including colour, clarity, cut and carat weight, a report number and other information.
A practical stocking log should, therefore, trace the reference number of the certificate or report back to the appropriate diamond.
This is especially helpful if a salesperson has to find information on a particular stone that they don’t have in one file.
How Should Diamond Inventory Be Tracked From Purchase to Sale?
An effective workflow that ties all of the stock movements to the corresponding diamond record.
Purchase, Receipt, Quality/Certificate Recording, Inventory, Memo/Transfer/Production Issue, Return or Sale, Final Stock Update
- For instance, let’s take a certified loose diamond that was bought by a wholesaler.
- Purchase: Record details of the supplier, stone details, cost, and certificate information.
- Receipt: Match the actual stone with the inventory record.
- Stocking: Place and record the type of stocking in the right place and mark it as stocked.
- Quotation or memo: Document the commercial transaction without the loss of the identity of the original stock.
- Return or sale: Update the status and history of sale for the stone.
- Reporting: Maintain the movement history for operational and financial reporting purposes.
The process can go into production for manufacturers:
Product and Promotional Action Processing (PPAP). Product and Promotional Action Processing (PPAP) is the ability to process and execute product and promotional actions for the finished jewellery.
That relationship is important since a diamond that comes out of the loose-stone inventory shouldn’t just vanish from the system.
Diamond Inventory Software vs Spreadsheet: Which Is Better?
For a small inventory and relatively simple tracking, a spreadsheet may be sufficient. This challenge comes into play when the business requires multiple users, locations, transactions, and detailed stone attributes.
| Spreadsheet-based tracking | The software for managing diamond inventories. |
| Adjustable for smaller stock levels | Structured stone-level records |
| Manual search and update. | Searchable attributes |
| Separate files may develop | Centralised inventory |
| Manually working with movement history can be time-consuming. | Transaction-based tracking |
| Certificates can be kept in a separate book. | References can be linked to inventory on a certificate. |
| Multi-user control can prove to be challenging | Specially developed for controlled multi-user workflows |
| Reporting may be manually prepared. | Inventory and management reporting |
It shouldn’t be a matter of “newer software”. If a dealer has a few dozen stones and doesn’t have to deal with many big ones, he may be able to handle it using a spreadsheet he designed himself. If you have thousands of stones, several branches, memos, manufacturing, or numerous transactions, then it is better to have dedicated software.
What Should You Check Before Choosing Diamond Inventory Software?
Test the software before buying with your own diamond workflow and not with a vendor’s sample database.
The following is a list of items that form a practical checklist:
- Does the system keep a record of shape, carat weight, measurements, colour and clarity?
- Is it possible to send certificate and/or grading-report information with the correct stone?
- Do staff have the ability to search multiple attributes?
- Is there any way to tell if the diamond is loose or jewellery set?
- Can the diamond parcels be dealt with where appropriate?
- Is it possible to track stock from branch to branch and warehouse to warehouse?
- Are stones allowed to be given to production and are they allowed to be returned?
- If necessary, can movements by memo or consignment be traced?
- Is any form of identification by barcode, QR or RFID codes appropriate?
- Are the inventory reports able to provide information that is meaningful?
- Will the system be able to integrate diamond inventory into accounting, sales, and other business processes?
- Does the implementation team have the flexibility to tailor the workflow to the company’s real-life operation?
This last question is often forgotten. Even if the software has the correct fields, it could not work if the purchasing, inventory, production, sales, and reporting processes were set up as separate activities.
How Karat ERP Can Help With Diamond Inventory Management
Karat ERP’s inbuilt product information equips the software for Jewellery manufacturing, wholesale, retail, and Diamond trading businesses. It has a Karat ERP solution for inventory management of precious metals, diamonds, stones, and even support for barcode, QR code, and RFID.

Karat Diamond Trading is a niche product for Diamond trading for those businesses that specialise in diamond trading. The current product page includes capabilities of loose diamonds, certified stones and transactions, inventory and loss control, style imaging and approvals, as well as export and contractor control.
GIA Integration is also mentioned in the diamond-trading section of the Karat website. That’s especially true if a diamond company is looking to have its inventory system handle grading and certificate data.
This will be determined by this business type: whether it’s a diamond trader, manufacturer, wholesaler, retailer, or a mix of these. The implementation process of Karat ERP begins with a system study of the existing workflow, followed by customisation, implementation, migration of data before implementation, and training of the users before going live.
To accurately assess the value, have the team simulate an actual operation: receive a certified diamond, search it based on its characteristics, navigate it from one place to another, or into production, record the change of hands, and report its status.
Conclusion
It’s not just about counting diamonds. The jewellery manufacturers, wholesalers, retailers, and diamond traders require a dependable means of identifying a diamond by shape, carat weight, size, colour, clarity, grading information and certificate, and also monitoring the location and movement of the diamond.
A spreadsheet might work for a small operation, but for more complex diamond businesses, it’s time to invest in a diamond inventory workflow solution that integrates stone information with diamond purchase, trade, production, sales and reporting.
When deciding on diamond inventory management software, try it with actual diamonds and real transactions. For businesses requiring integrated diamond trading and jewellery operations, it’s important to assess the solution beyond just its features and capabilities; Karat ERP should be demonstrated through a workflow process.
Frequently Asked Questions
1. What is diamond inventory management software?
Diamond inventory software is a special type of software that is used to keep records and track diamonds based on their shape, carat weight, colour, clarity, cut and certificate information. It can also record important information, such as location and status, and the buying and selling of diamonds, making it easier for diamond traders and jewellery businesses to locate and reconcile exact stones.
2. What information should be recorded for each diamond?
Typically, a diamond record should include the properties of the business, such as stone/stock ID, shape, carat weight, measurements, colour, clarity, cut, and certificate/report number if available. Other fields like supplier, cost, location, status, fluorescence, polish and symmetry can be helpful depending on the trading workflow.
3. Can diamond inventory software track certified diamonds?
Yes, appropriate diamond inventory systems can document certificate and/or grading report data for each stone. This can make it easier to document the characteristics of a diamond and know that it is one of the certified diamonds. The certification fields and lab integrations will differ with software and should be tested during the product demo.
4. Is diamond inventory management software useful for jewellery manufacturers?
Yes. Diamond inventory management software can be used on the pre-production side to monitor the movement of stones before they go into production, and on the finished jewellery side to link the stones issued and returned to work-in-progress and finished jewellery. This will help to avoid an inventory discrepancy when the loose stone has been moved into a production process where an unexplainable discrepancy might otherwise be found.
5. How should a business choose diamond inventory management software?
Test your specific workflow and choose software that performs that function, not just look at the features. Review stone-level attributes, certificate handling, search and filtering, inventory movements, multiple locations, production integration, reporting and user controls. If you sell diamonds, as well as make or sell jewellery, test the entire process from buy to sell.
