Hi everyone, I am planning to pop the question officially to my long time GF of 9 years. I know she has been patiently waiting for me to ask her the question.

I have zero knowledge on gold/diamond/platinum etc.
Yes I tried to google and find out, but there are way too many things to absorb.

First and foremost is my budget is rm1.5k ( saving up for a house to surprise her soon)
Because there will be another ring from my side during our official engagement, thus I need to prepare my budget for TWO rings.

Which retailer should I go to?
Possible to get a diamond ring with that budget?
My GF can only wear gold(that is what she told me few years back as she is allergic to other type of metals, white gold/platinum I am not sure)
I kinda want to get the ring within a week.

And what other factors that I need to consider before I do the purchase?
All advice and comments are welcomed.
