Entity Definition & Overview

What is OctaGems?

OctaGems jewelry ERP is specialized custody and inventory management software engineered specifically for diamond dealers, manufacturing jewelers, luxury retailers, and watch traders. It operates a single-ledger architecture linking workshop job orders, consignment memo tracking, RapNet list discount pricing, and customer invoicing into one synchronized system.

Inventory

One stock list. Three kinds of goods.

Most systems count everything in pieces, but a GIA stone, a bag of melee and a ring design are three different kinds of stock. OctaGems counts each one in its own unit, so the numbers are right from the start.

Single stones & watches

Certified diamonds, gemstones, luxury watches and one-off pieces. Each one is a single item with its own cost and its own history.

Counted in
1 piece, always

Example

Parcels & lots

Melee and uncertified goods sold by weight. You can split a parcel, mix parcels together or pull stones out, and the average cost per carat updates each time.

Job work

Make it in a job. Know what every piece cost.

Open a job order for a collection or a customer order. Upload each vendor invoice and OctaGems reads the vendor, invoice number and lines for you. Split every line across the pieces it went into, equally or by gross weight, and each finished piece goes to inventory at its true cost.

  • Every vendor invoice in one place: diamonds, CAD, casting, metal and labor.
  • Duplicates caught. The same vendor invoice can't be entered twice.
  • Cost locked. Once a piece is in inventory, its cost can't change.

AI assist

Stop typing. Scan it or say it.

Drop in a vendor invoice and OctaGems reads it into a purchase order. Or say what you sold and it drafts the invoice. Fields it isn't sure about are marked for you to check, and nothing is saved until you confirm.

Memo & custody

Goods on memo are still yours.

Goods out on memo stay your stock, at your cost, in someone else's hands. OctaGems tracks who owns a stone and who is holding it as two separate states, so your memo exposure and stock value stay accurate.

STEP 01

Issue Memo Slip

Select certified stones or finished jewelry, assign recipient dealer, and set return terms.

STEP 02

Track Custody

Goods remain on your balance sheet at cost while aging bars track exposure and due dates.

STEP 03

Convert or Return

One click converts sold items to tax invoices; returned goods check back into your vault safe.

    Invoices & payments

    Invoice from the memo. Follow every dollar in.

    Convert a memo to an invoice and the stock, the receivable and the memo all update together. Record payments as they arrive, in full or in parts, and see what's still on its way.

    • Any payment method: wire, check, card or cash, with the account it landed in.
    • Cleared, not just received. Money in transit stays flagged until the bank clears it.
    • Card fees kept apart. The customer's balance is settled in full; the fee is booked as your cost.
    • Consignment handled. Sell goods you hold on memo and the vendor bill is raised for you.
    Pricing

    Quote in points back. See your margin as you type.

    Dealers price stones as a discount off the Rap list. OctaGems keeps every price tied to the list version it was set against, so a new Thursday list never changes your margins without you knowing.

    • Price history by customer, vendor, shape and size band.
    • Margin floors that send low prices to a manager for approval.
    • Revaluation reports each time a new list is published.

    RFID & barcode

    Count a whole tray in seconds.

    Read every tag in a tray at once and compare the result with what the system expects. When a stone is missing, OctaGems checks memos and transfers first, so you know straight away whether it's actually lost.

    • Weekly counts instead of a once-a-year stock take.
    • Barcode and QR labels printed from the item record.
    • Every move recorded: tray, safe, branch or customer.
    Mobile app

    Your stock, memos and invoices, in your pocket.

    The OctaGems Android app puts the same ledger on your phone. Look up any piece at a show, send a memo from the counter, and record a payment the moment it lands.

    • Inventory and memo on the go: find any piece, see where it is and its full history, and send memos.
    • Invoices and payments: create an invoice, or say it, and record payments as they arrive.
    • Reminders that matter: memos coming due, overdue invoices and payments received.
    • Photos from your camera: shoot items, certificates and vendor invoices straight into the record.

    OctaGems tracks consignment goods by separating legal ownership from physical custody. When stones or jewelry are placed on memo out, they remain on your balance sheet at cost while recording recipient terms and due dates. Automatic aging alerts prevent misplaced goods, and items convert into sales invoices with one click.

    OctaGems connects every supplier purchase order—including loose diamonds, CAD design, metal casting, stone setting, and polishing—to a specific job order. Costs are automatically allocated across finished pieces equally or by weight, locking in an accurate cost basis before finished jewelry enters your saleable inventory.

    OctaGems ties diamond inventory directly to Rapaport Diamond Report price lists. You quote prices based on dealer discount percentages off Rap. Built-in margin floors prevent unauthorized discounts by routing below-floor quotes to managers for sign-off, protecting your company's gross profit margin on every transaction.

    Using compatible RFID scanners, OctaGems reads entire trays of tagged diamonds and finished jewelry simultaneously in seconds. The system immediately compares physical tag scans against expected safe and tray locations, flagging missing items, checking active memo slips, and logging branch transfers to eliminate manual stocktakes.

    Yes. OctaGems lets you store and cross-reference report numbers from GIA, IGI, and HRD directly inside stone records. Graded carat weights, color, clarity, and cut parameters are linked to official report PDFs, ensuring wrong certificates or mismatched report numbers are caught before goods leave your premises.

    Yes. OctaGems provides a dedicated mobile companion app for Android connecting directly to your central ledger. Staff can search stock across vaults, issue memo slips at trade show counters, snap invoice photos into job records, and record incoming payments remotely from any location.

    Yes. OctaGems supports global jewelry trading in USD, EUR, GBP, HKD, and other major currencies. The system applies region-specific sales tax rules, customs tariff fields, and line-level discount terms to generate professional international quotes, proformas, memo slips, and commercial tax invoices with proper currency formatting.

    Administrators configure granular permissions restricting team members to view, create, edit, or approve specific modules like job orders, memo slips, or financial invoices. Custom approval thresholds enforce manager sign-off whenever pricing discounts or credit limits breach predefined company margin parameters.

    Each jewelry business operates on an isolated tenant partition with strict role-based access controls. Data is encrypted in transit using modern TLS and encrypted at rest. Customer records, inventory values, and proprietary trade pricing remain strictly your property and are never shared or used for advertising.

    You can request a personalized walkthrough using the demo booking form on this page or by emailing support@octagems.com. The OctaGems onboarding team reviews your current inventory workflow, imports sample stock data, and demonstrates job costing, memo custody, and invoicing live with your real business requirements.
