Certification Guide

Your Assurance of Authenticity, Quality & Trust in Jewelry

At Diamond Tiara Crown by Costozon, we believe that luxury should come with transparency and trust. Whether you’re investing in a dazzling diamond tiara, a sterling silver crown, or a regal gemstone headband, certification plays a vital role in verifying the authenticity, purity, and value of your jewelry.

This Certification Guide explains what certifications are, why they matter, and how Diamond Tiara Crown ensures every piece is backed by quality standards you can count on.

1. What Is Jewelry Certification?

A jewelry certificate is an official document issued by an independent or government-authorized body that confirms specific characteristics of the metal and stones used in a jewelry piece.

Certification provides proof that:

  • The diamonds or gemstones are genuine and ethically sourced

  • The metal (e.g., silver or gold) is of a specific purity

  • The jewelry meets recognized quality standards

Think of it as your jewelry’s passport of authenticity.

2. Why Is Certification Important?

Here’s why certification matters, especially when buying luxury items like tiaras, crowns, and gemstone sets:

  • ✅ Authenticity – Confirms the diamond/gemstone is not synthetic or fake

  • ✅ Purity – Verifies the metal’s karat or fineness (e.g., 925 silver or 18K gold)

  • ✅ Valuation – Helps determine fair price for resale or insurance

  • ✅ Trust – Builds buyer confidence in online and international purchases

  • ✅ Transparency – Protects you from misleading claims

At Diamond Tiara Crown, we provide certification or documentation for diamonds, metal purity, and hallmarking on request or where applicable.

3. Types of Certifications We Offer

We use third-party gemological labs and government-recognized hallmarking bodies to certify the following:

A) Diamond Certification

Diamonds are evaluated using the 4Cs: Cut, Clarity, Carat Weight, and Color. Diamond certification confirms:

  • Stone is natural (not synthetic or lab-created unless disclosed)

  • Grading is professionally assessed

  • No undisclosed treatments have been applied

We work with:

  • IGI (International Gemological Institute)

  • GIA (Gemological Institute of America) – by request

  • SGL (Solitaire Gemological Lab) – widely used in India

You may receive a certificate, seal, or grading card with the item.

B) Metal Purity Certification (BIS Hallmark)

We use 925 sterling silver as our base metal in most designs.

  • Hallmarked by the BIS (Bureau of Indian Standards)

  • Confirms silver purity is 92.5%

  • BIS stamp is included on most silver jewelry items

For gold items (custom orders), we offer:

  • BIS 14K/18K Gold Hallmarking

  • Gold weight and purity declaration on invoice

C) Gemstone Certification

Each natural gemstone (e.g., ruby, emerald, sapphire) may be accompanied by:

  • Gem testing report (from a reputed gemological lab)

  • Description of color, cut, treatment (if any), and origin (if available)

  • Confirmation that the stone is natural or lab-created

We also offer on-request testing if you require a lab certificate with your purchase.

4. How to Read a Diamond or Gem Certificate

While certificates may vary slightly, most will include:

  • Shape and cut of the stone (e.g., Rose Cut, Cushion, Round)

  • Carat weight

  • Color grade (D to Z scale for diamonds)

  • Clarity grade (from FL to I3)

  • Cut grade (Excellent, Very Good, etc.)

  • Measurements

  • Fluorescence or treatments (if applicable)

  • Unique certificate number

This number can often be verified online via the lab’s website.

5. BIS Hallmarking for Sterling Silver

All of our 925 sterling silver tiaras, crowns, and jewelry are either:

  • Hallmarked with the BIS 925 mark, or

  • Accompanied by weight and purity details on the invoice

The BIS hallmark consists of:

  • BIS logo

  • Purity mark (e.g., 925)

  • Assaying center mark

  • Year code

This ensures your piece meets international silver standards, is legally recognized, and holds long-term value.

6. Lab-Grown Diamond and Moissanite Options

For budget-friendly or sustainable preferences, we offer lab-grown diamond or moissanite options on request.

  • Lab diamonds can be certified by IGI or SGL

  • Moissanite can include a certificate for refractive index and cut

  • All alternative stones are clearly marked during purchase

This way, you always know what you’re buying — and can buy with confidence.

7. What If a Product Doesn’t Come with a Certificate?

Some smaller items (e.g., accent stones or lightweight silver jewelry) may not come with physical certificates, but:

  • Product details will clearly state metal purity and gemstone type

  • We will provide written authenticity confirmation via invoice or order note

  • Certification can be arranged on request for an additional fee (if needed for appraisal or gifting)

We never use imitation or synthetic materials without full disclosure.

8. Protecting Your Purchase with Documentation

To preserve the value and verify authenticity in the future, always:

  • Keep your certificates and invoices in a safe place

  • Photograph the hallmark or diamond if needed

  • Save unboxing videos for insurance or dispute resolution (especially for international shipping)

In case of resale, gifting, or insurance claims, certification serves as your jewelry’s identity and value statement.

9. How We Ensure Certification Integrity

At Diamond Tiara Crown, we take quality assurance seriously. Our process includes:

  • Sourcing gemstones and diamonds only from reputed suppliers

  • Getting items tested or certified by authorized labs

  • BIS hallmarking via recognized centers

  • Verifying every detail before shipment

  • Transparent pricing backed by proper documentation
