you can go to Houston Centre in TST East, opposite the Auto Plaza.
there are a few small jewelry shops there.
they are quite exclusive, doors are locked, u have to press the bell, before they let you in.
they usually sell only the diamond, then u pick a design before they set it for you.
prices are very competitive at these shops...
you can get a 1.0 Carat, VVS, Color F diamond for as cheap as HKD20k+.
compared to other Big Brand stores like CTF, such a diamond u need to pay like HKD80~100k...
you can opt to pay a fee for the IGI or GIA cert.. if you are worried abt the authenticity.
if you want to buy a damond,
choose clarity:VVS color:F
why?
for color, D, E, F, they are in the Colourless category.
G, H, I, J are in the Near Colourless cat.
in the top tier, obviously D is the most expensive.. F much cheaper, but to the naked eye, you can tell teh difference.
G is just slightly cheaper than F, but yet F is in the top tier...
when you show the GIA cert, your wife/girlfren will be happier to know her diamond is in the Colourless tier.
as for size, avoid 1.01 carat...when buying in HK.
it is usually more expensive than 1.02 ~ 1.09..
why?
it represents "1 and only 1"
a stupid gimmick that mark-up the price.
