* 22K Gold (91.6%) – Popular for jewelry, durable but still soft
* 18K Gold (75%) – Stronger, perfect balance of purity & durability
* 14K Gold (58.5%) – Common in Western jewelry, affordable & durable
* 10K Gold (41.7%) – Lowest karat allowed in jewelry, very durable

# # # 🔹 By Color (Alloy Mix)

* Yellow Gold – Classic, traditional blend of gold + copper + zinc
* White Gold – Modern look, mixed with palladium/nickel + rhodium finish
* Rose Gold – Romantic, pink hue from gold + copper
