Karat (KT) measures how much pure gold is in your jewellery. Pure gold is 24KT — too soft for daily wear. Goldsmiths blend it with alloys (silver, copper, palladium) to create durable, wearable metals.

| 9KT | 37.5% | 375 | Daily-wear, diamond-set |
Why EXOTIC DIAMONDS Uses 9KT Gold
- Durability — 9KT is significantly harder than 18KT and 22KT, making it ideal for prong settings that hold diamonds securely for decades.
- Scratch Resistance — The higher alloy content means less denting and warping over years of wear.
- Accessible Luxury — Same gold colour, same hallmark guarantee, ~50% less metal cost — letting you put the savings into a larger, better diamond.
- BIS Hallmarked — Every piece carries the official BIS 375 hallmark, certified by the Bureau of Indian Standards.
Will 9KT Gold Tarnish?
No. 9KT gold is highly resistant to tarnishing and won't react with water, sweat, or perfume. Like any fine jewellery, we recommend storing it dry and giving it an occasional clean with a soft cloth.
Does It Look Different from 18KT?
To the naked eye, no. 9KT yellow, white, and rose gold are colour-matched to industry standards. The difference is structural — 9KT is denser and more resilient.
Is 9KT Real Gold?
Yes — absolutely. The 375 BIS hallmark is your guarantee that the piece contains 37.5% pure gold by weight. It's officially recognised gold in India, UK, USA, and across Europe.
