Q: What is BIS hallmarking?

BIS (Bureau of Indian Standards) hallmarking is India's government certification of gold purity. A BIS 375 hallmark certifies that a piece contains 37.5% pure gold (9 karats). It is a legal standard, not cosmetic. Every UNPLATED piece carries a BIS 375 hallmark that can be verified using the BIS CARE app.

Question 1

Why 9K gold?

Accepted Answer

9K gold is 37.5% pure gold alloyed with metals that make it harder, more wearable, and more affordable than 18K or 22K. Higher gold content means softer metal — 9K holds fine detail and resists daily wear better than higher karats. Every UNPLATED piece is BIS 375 hallmarked: government-certified and verifiable.

Question 2

Does 9K gold tarnish?

Accepted Answer

No. Solid gold does not tarnish, react to skin, or fade with daily wear. Unlike silver, unlike gold-plated jewellery, and unlike gold-filled pieces — solid 9K gold is inert and stays the same colour indefinitely.

Question 3

What is BIS hallmarking?

Accepted Answer

BIS (Bureau of Indian Standards) hallmark = government-certified gold purity. It's not optional, and it's not cosmetic — it's a legal standard.

Question 4

How do I care for solid gold jewellery?

Accepted Answer

Store pieces separately to avoid scratching. Clean with mild soap and warm water when needed. Avoid prolonged exposure to bleach, chlorine, or harsh chemicals. Solid gold is built to last — it does not require special maintenance or professional cleaning for everyday wear.
