Diamond jewellery in India usually comes in 14Kt or 18Kt gold – not the 22Kt used for plain gold jewellery. Here's why, and how to pick the right one.
Why not 22Kt for diamonds?
22Kt gold is soft. Diamonds are held by tiny metal claws (prongs), and soft gold can bend, letting a stone loosen or fall out. 14Kt and 18Kt are mixed with stronger metals, so they hold diamonds securely.
The difference at a glance
| 14Kt | 18Kt | |
| Pure gold | 58.5% | 75% |
| Colour | Slightly lighter | Richer, warmer |
| Strength | Harder, more scratch-resistant | Strong, slightly softer |
| Price | Lower | Higher |
| Exchange value | Lower (less gold) | Higher (more gold) |
Choose 14Kt if…
- You want an everyday piece you'll wear to work, the gym or while travelling.
- You want more diamond for your budget – the gold saving can go into a bigger design.
- It's a gift for a first diamond.

Choose 18Kt if…
- It's for a wedding, engagement or anniversary – a piece meant to last generations.
- You prefer the richer gold colour, especially in rose and yellow gold.
- You care about exchange value later.

Does karat change the diamond?
No. The diamonds are the same quality either way. At Tattvaa all pieces use E-F colour, VVS clarity natural diamonds. Only the gold changes.
Our recommendation
For daily-wear nose pins, studs and light earrings, either works well. For rings and bridal jewellery, 18Kt is the classic choice. Still unsure? Visit our R.S. Puram studio in Coimbatore and compare both side by side, or WhatsApp +91 95909 36673.
