Karat measures gold purity, 1 karat = 1/24 gold purity. With 24 karats being pure but soft, less ideal for jewelry. Gold is alloyed for durability, like 18 karat (75% gold) for intricate pieces, and 14 karat (58.3% gold) for a balance of strength and affordability. This applies to yellow gold, white gold, and rose gold. For your information, our 18-karat yellow gold has a richer hue compared to 14-karat yellow gold. The tone of our yellow gold is soft and subtle, avoiding an overly yellow appearance. As for 18-karat rose gold, the color is also deeper than that of 14-karat rose gold.
To determine the size of the bracelet you need, use a string, a pencil, and a ruler. Wrap the string around your wrist so that it goes all the way around, then use the pencil to mark where the two ends of the string meet. Then, take the string and measure its length using your ruler, in inches. Here is a size chart.
| Size of your wrist | Size you should take |
|---|---|
| 5 inches and a half | 6 inches |
| 6 inches | 6 inches and a half |
| 6 inches and a half | 7 inches |
