Shop 2,000+ designs, from diamond studs and peacock pendants to nose pins, mangalsutras and tennis bracelets, each sent directly from the brand.
Choose 18kt gold jewellery when colour and finish matter most: bridal and festive pieces, heirloom gifts, and jewellery you want to look unmistakably like gold.
What Makes 18K Gold Different?
18K is 18 parts gold out of 24, alloyed with 25% copper, silver or palladium. The higher gold content gives:
- Richer colour – a deeper, more saturated yellow than 14k gold jewellery or 9k gold jewellery.
- A smoother feel – softer metal that takes fine detailing, filigree and high polish beautifully.
- Strength for stones – unlike 22K, 18K is hard enough for prong and pavé settings, which is why it's the classic metal for diamond jewellery.
Is 18k gold real gold? Yes – it is solid gold, three-quarters pure, with no plating.

Lab-Grown Diamonds and Gemstones in 18K Gold
Most 18K pieces here are 18k gold with lab grown diamond settings. Lab-grown diamonds are chemically the same as mined diamonds, and 18K's warm tone makes them glow; white gold settings make them look whiter still. Explore every gold and diamond jewellery design.
18K is also the karat for colour: pearl, ruby, emerald, sapphire, topaz, amethyst, citrine and tanzanite, plus traditional navratna pieces that set nine stones together.
18K Yellow, White or Rose Gold?
18k yellow gold is the traditional Indian choice and flatters warm and wheatish skin tones. 18k white gold is alloyed with whiter metals and usually rhodium-finished – a cool backdrop for diamonds and black diamonds. Some designs come in 18k rose gold, warmed with extra copper. Every colour holds the same 75% gold.
Is 18K Gold Good for Daily Wear?
Yes, for most pieces. Studs, pendants and nose pins rarely knock against anything, so 18k gold for daily wear works well. Rings and bracelets take more wear; 18K may show fine scratches sooner than 14K, which a jeweller can polish out. When buying, look for the BIS hallmark – the logo, "18K750" and a six-digit HUID you can check in the BIS Care app.
18K Gold for Weddings, Festivals and Gifting
18K's rich colour sits naturally with a silk saree or a lehenga – a diamond pendant set for the wedding reception, a pearl drop for the mehendi, a nath for the bride. For Diwali, Akshaya Tritiya or an anniversary, an 18k gold gift such as studs or a pendant is a piece she'll keep for years.

Frequently Asked Questions
1. Is 18K gold real gold?
Yes. 18K is solid gold with 75% pure gold and 25% alloy metals. The alloy adds strength; the colour and value come from the gold.
2. What does 750 mean on gold jewellery?
750 is the purity mark for 18K gold – 750 parts per thousand are pure gold. In India it appears as "18K750" in the BIS hallmark, next to the HUID code.
3. Why is 18K gold used for diamond jewellery?
It balances gold content with hardness. 18K holds prongs and pavé settings securely, while 22K and 24K are too soft to keep stones safe.
4. Does 18K gold tarnish?
18K yellow gold doesn't tarnish in normal wear. White gold may slowly show a warmer tone as its rhodium finish wears, and a jeweller can re-plate it.
5. Which karat gold is best for a necklace?
18K is a popular choice for necklaces and pendants because the colour is rich and a necklace sees little friction. For very fine chains worn non-stop, 14K adds a little extra strength.
6. Is 18K gold good for rings?
Yes – it's the classic karat for engagement and diamond rings. It may scratch a little faster than 14K, so remove it for gym work and heavy chores.
7. 18K vs 14K gold – which is better?
18K has more gold and a deeper colour; 14K is harder and a little more budget-friendly. Our 10k vs 14k vs 18k gold guide compares them in detail.
8. Can I wear 18K gold in water?
A splash won't harm it, but chlorine and harsh soaps can dull the finish and loosen stones over time. Take pieces off before swimming or cleaning.
9. How do I clean 18K gold jewellery?
Soak it in lukewarm water with a drop of mild soap, brush gently with a soft toothbrush, rinse and pat dry. Pearl pieces should only be wiped with a soft cloth.
