What is KDM and Hallmarked Gold Jewellery?

What is KDM and Hallmarked Gold Jewellery?

For generations, Indian households have trusted gold as a reliable form of savings and a symbol of prosperity. However, the terms used in the gold market can sometimes be confusing for buyers in Gujarat. Two terms you might hear often are KDM and Hallmarked jewellery. Understanding the difference between them is vital to safeguarding your investment.

What is KDM Gold?

Historically, gold ornaments were crafted by soldering different pieces together. To join these parts, craftsmen used a solder alloy made of gold and cadmium. This technique was known as KDM soldering.

  • The Benefit: It allowed for intricate designs with minimal loss of gold purity at the joints.
  • The Drawback: Cadmium fumes are toxic to artisans, and KDM jewellery could cause skin allergies for some wearers. Due to these health concerns, KDM gold has been phased out and replaced by safer alternatives.

What is Hallmarked Gold?

Today, hallmarked gold is the safest standard for purchasing jewellery in India, including cities like Ahmedabad. Hallmarking is an official certification process managed by the Bureau of Indian Standards (BIS). It guarantees the exact purity of the gold you buy.

  • The Standard: Under current regulations, hallmarking is mandatory for gold jewellery.
  • The Marks: Look for the BIS logo, the purity grade, and the unique identification number on the inside of the ornament.

Why You Should Choose Hallmarked Jewellery

When you shop for gold in the Bavla area of Gujarat, choosing hallmarked pieces offers several advantages:

  • Guaranteed Resale Value: You get the exact market value of the gold purity marked on your jewellery during exchange or resale.
  • Quality Assurance: There is no risk of getting low-quality gold mixed with cheaper metals.
