Sometimes it's about one's skin tone. Silver works well for cool and neutral skin tones, while gold suits warm undertones.
Pure gold also retains it's shine much longer while silver jewellery turns black faster.
+ Gold has more value and thus ended up with more regal look. Silver often give a bold contrast to darker skin tone. So it also depends on occasional choice.
Not to forget in countries like India gold jewellery was quite important for women because of it's value, and personal financial security.
Married women had absolute right to their dowry or gifts they got at the time of their wedding under traditional Hindu laws. (and their inheritance etc) Only wealthy families would give away land or property to their daughter. But she would get valuables, money and jewellery in dowry or stridhan or as gifts and theoretically and legally husband could not touch it. If in case of some financial emergency he took wife's jewellery or anything else from her stridhan (woman's endowment), he was supposed to return it with interest at market rate when his condition improved. Meaning it was considered a debt under the law.
However in practice, money in hand is easily spent. Property often ended up in hands of husband because most housewives wouldn't run around managing it. On top of it, when British colonized India, they made it practically impossible for women to hold any land despite traditional laws and rights..
English common law still leaned on the concept of coverture (where a woman's legal rights were subsumed by her husband). Colonial courts consequently struggled with the idea of independent female landowners and routinely scaled back women's property rights into heavily restricted "life estates"—meaning a woman could use a property to survive, but could never truly own or sell it. So that bias ruined property rights of Hindu women in India.
Formalizing regional customary laws—such as the Punjab Customary Law or the Mitakshara system—they explicitly recognized only the claims presented by the leading men of landowning castes. This effectively froze fluid local customs into rigid, legally binding text that explicitly blocked daughters and widows from inheriting or alienating land. The revenue settlements like the Permanent Settlement, implemented by the British required clear, individual titles to streamline tax collection. They granted these land deeds (pattas) almost entirely to male heads of households, completely bypassing any customary usage or shared security that women previously held within family structures
So even poor people tried to give at least some pieces of jewellery to their daughters at the time of their wedding or other occasions. It was not just ornaments but financial support. If they could not afford gold it would be silver. It was a critical safety net for them. Because touching personal jewellery of wife meant husband accepting that he had exhausted all other options and was already completely broke. It becomes a pride and honour issue in traditional families. So this was what women still managed to hold on to personally, for the longest time.
