Buying fine jewelry online means trusting documentation you cannot hold in your hands until delivery. For lab grown diamond rings, necklaces, bracelets, and wedding bands, especially purchases in the hundreds or thousands of dollars that documentation is usually an independent grading report.
This guide explains how to read, verify, and match an IGI lab grown diamond report to the stone you receive. It applies whether you shop with Bright Brilliance or any other retailer. Our goal is simple: give you a clear checklist, so certification supports your decision not marketing language alone.
Why Verification Matters for Online Fine Jewelry
In a store, you inspect a diamond under light, compare options side by side, and ask questions in real time. Online, the grading report becomes your primary reference.
A report from an accredited laboratory such as the International Gemological Institute (IGI) records measurable quality attributes cut, color, clarity, and carat weight and states whether the stone is natural or laboratory-grown. For lab grown diamonds, the report should clearly identify origin as lab-created while grading the stone using the same standards applied to mined diamonds.
Verification matters because:
- It confirms what you ordered. Grades and measurements on the report should match the listing and your invoice.
- It creates a shared reference. You and the seller can discuss the stone in documented terms not vague descriptions.
- It supports high-value confidence. When you cannot see the piece before paying, documentation is your pre-purchase proof point.
- It catches problems early. Checking the report before production (on custom orders) and again at delivery reduces disputes later.
Verification is not paranoia. It is standard practice for any significant jewelry purchase made online.
What an IGI Lab Grown Diamond Report Includes
While report layouts vary slightly by shape and laboratory update cycle, a complete IGI lab grown diamond grading report typically includes:
| Section | What it tells you |
|---|---|
| Report number | Unique ID tied to this specific grading event |
| Date issued | When the stone was graded |
| Origin statement | Identifies the stone as laboratory-grown |
| Shape and cutting style | Round, oval, cushion, emerald cut, etc. |
| Measurements | Length, width, depth in millimeters |
| Carat weight | Recorded to two decimal places |
| Color grade | Usually D–Z scale for diamonds |
| Clarity grade | From Flawless (FL) to Included (I) |
| Cut grade | Where applicable to the shape |
| Proportion diagram | Visual outline of the stone's cut |
| Laser inscription note | If the report number or code is inscribed on the girdle |
Keep the report with your jewelry. Store a digital copy as well. You will need it for insurance, resale, and future verification.
The 5-Step Verification Checklist
Use this checklist before you pay (when possible) and again when your order arrives.
Step 1: Locate and save the report number
Every IGI report has a unique report number, usually printed prominently on the document. Before committing to a purchase:
- Ask the seller for the report number associated with the stone in your order.
- Confirm the number appears on the actual report, not only in a product description.
- Save a screenshot or PDF copy for your records. If you are ordering a made-to-order piece, request confirmation of which stone (and report) will be set before production begins.
Red flag: The seller cannot provide a report number or gives different numbers at different stages.
Step 2: Read the 4Cs in plain language
The four Cs - cut, color, clarity, and carat are the core quality attributes on the report.
Cut
Cut affects how light travels through the stone. On round diamonds, IGI assigns a cut grade (Excellent, Very Good, etc.). Fancy shapes may emphasize polish and symmetry.
Color
Diamond color grades run from D (colorless) toward Z (noticeable tint). For lab grown diamonds, color is graded on the same scale.
Clarity
Clarity describes internal characteristics and surface features. Grades range from Flawless to Included.
Carat weight
Carat is weight, not physical size alone. Confirm the report carat matches your order specification exactly.
Step 3: Match measurements and shape
- Shape — Round, oval, cushion, etc. must match your order.
- Measurements — Length × width × depth (in mm) should align with the listing.
This step matters for custom and made-to-order orders where you chose a specific size and shape.
Step 4: Verify the laser inscription (when present)
Many IGI graded diamonds carry a laser inscription on the girdle a microscopic line visible under magnification.
- Ask the seller whether the stone is inscribed (the report will note this).
- Use a jeweler's loupe (10× magnification) or visit a local jeweler to view the inscription.
- Confirm the inscription matches the report number on your document.
Red flag: The report references an inscription, but none is visible or the inscription does not match.
Step 5: Confirm the report arrives with the jewelry
- The physical report (or an official digital copy) is included.
- The report number matches what was confirmed pre-purchase.
- The grades and measurements still match your order specification.
For Bright Brilliance orders, every lab grown diamond ships with its IGI certification. Keep the report with your receipt.
What a Grading Report Does Not Cover
| Covered on report | Not covered on report |
|---|---|
| Diamond quality grades (4Cs) | Setting craftsmanship or prong quality |
| Origin (lab grown vs. natural) | Metal type purity (14K vs. 18K gold) |
| Measurements and shape | Ring size, chain length, bracelet fit |
| Report number and inscription | Insurance replacement value (separate appraisal) |
| Date of grading | Brand reputation or seller return policy |
A grading report documents the stone. The mount (ring setting, chain, clasp) is a separate specification. Confirm both before you buy.
Red Flags: When to Pause Before You Pay
- No independent report from a recognized laboratory
- Report number changes between quote, invoice, and delivery
- Grades on the listing do not match the report
- Origin not stated as laboratory-grown on a stone sold as lab grown
- Seller refuses to share report details before payment on a significant purchase
- Price far below market for the stated grades with no documentation
- Inscription mismatch between report and physical stone
Lab Grown Diamonds and Certification: Quick Context
Lab grown diamonds are real diamonds with the same chemical composition and optical properties as mined diamonds. Grading laboratories evaluate them as diamonds and mark the origin as laboratory-grown on the report.
IGI operates as an independent gemological laboratory. Bright Brilliance certifies every lab grown diamond in its catalog through IGI not as a marketing label, but as a documented quality record you can verify.

Frequently Asked Questions
Can I look up an IGI report number online?
IGI offers report verification through its official channels. Use the laboratory's published lookup tools, not third-party sites.
Does a grading report guarantee my ring's total value?
No. The report documents diamond quality attributes. Insurance appraisals include metal, setting labor, and market factors.
Should I verify before or after I pay?
Ideally, before, especially on custom orders. At minimum, verify at delivery before the return window closes.
Is IGI as reliable as other major laboratories?
IGI is an established independent laboratory used globally. Bright Brilliance uses IGI for every lab grown diamond in its catalog.
What if my report does not match my order?
Contact the seller immediately with photos. Do not resize or reset the ring until the discrepancy is resolved.
Do I need a loupe at home?
Helpful but not required. A 10× loupe is inexpensive. A local jeweler can also verify in minutes.
