Consumer Guide: Verifying Hallmark 22K/18K Jewellery, Certified Solitaires, and Genuine Rudraksh in Bihar
Published on July 17, 2026
Buying gold, diamonds, and spiritual items is a major financial and emotional investment for families across Bihar. With local markets expanding rapidly, from Patna's bustling Sarrafa market to regional boutique jewelers, it is more important than ever to understand how to verify the authenticity of your purchases. Whether you are shopping for a wedding or looking for a long-term investment, this guide will help you identify genuine hallmark jewelry and certified stones.
UNDERSTANDING BIS HALLMARK: 22K VS 18K GOLD
The Bureau of Indian Standards (BIS) has made gold hallmarking mandatory to protect consumers from fraud. When purchasing gold, you should never take the jeweler's word for it. Always look for three specific marks engraved directly on the jewelry:
The official BIS logo.
The purity grade in Karat and fineness. For example, look for "22K916" for 22 Karat gold (which is 91.6% pure gold), or "18K750" for 18 Karat gold (which is 75% pure gold and highly recommended for diamond settings).
The 6-digit alphanumeric HUID (Hallmark Unique Identification) code.
To verify your purchase, download the official 'BIS Care' app on your smartphone. You can enter the 6-digit HUID code right at the jewelry counter. The app will immediately show you the jeweler's registration details and confirm the exact purity of the item you are holding.
CERTIFIED SOLITAIRES AND GEMSTONES
Unlike gold, gemstones and diamonds require a completely different type of scientific verification. You should never buy a solitaire diamond or a precious gemstone without a recognized laboratory certificate.
Look for certifications from trusted, independent global entities like the GIA (Gemological Institute of America) or the IGI (International Gemological Institute). A legitimate and transparent jeweler will always provide this physical or digital certificate. The certificate maps out the exact 4 Cs of your stone: Cut, Color, Clarity, and Carat weight. It acts as the "passport" for your diamond, ensuring its resale value in the future.
AUTHENTICATING A GENUINE RUDRAKSH
Spiritual jewelry holds immense personal value, but the open market is unfortunately flooded with synthetic or carved wooden counterfeits. A genuine Rudraksh seed has natural, well-defined compartments known as Mukhis.
When looking for authentic pieces—whether you are purchasing a single sacred bead or a beautifully crafted pair of tops set in gold—always rely on specialized, trusted names like Rudraksh Ratan that prioritize quality and rigorous authenticity. While traditional tests like the "water float test" are popular, laboratory X-ray testing remains the most foolproof method to see the internal seed structure. Your safest route is always purchasing from a certified seller who guarantees the geographic origin of the bead and provides a valid lab certificate.
FINAL PROTECTIVE TIPS FOR BIHAR CONSUMERS
Always ask for a computerized, finalized GST invoice.
Ensure that the unique HUID numbers of every individual item you purchased are clearly printed on the receipt.
Check the daily live 24K and 22K gold rates on the BiharGuru dashboard before stepping out to shop so you can calculate the exact making charges.
Never compromise on proper certification just to secure a slight discount on the final price.
By staying informed and vigilant, you protect your hard-earned money and ensure that your investments in jewelry and gemstones hold their maximum value for generations to come.
