Does purchasing gold for investment during the second lunar year change the starting date of the lunar year for calculating zakat from March to October, or does the original lunar year continue as is?

Scholars differed regarding the zakat on jewelry intended for trade: Al-Shafi'i held that zakat is due on its value, while Malik considered its weight. The preferred opinion is that craftsmanship has an intended value, and therefore it must be considered, just like quality in other zakatable assets.
