Balanced Choice

This is choice for you, if you are looking for a diamond which
offers you a good balance of colour, cut, clarity, and carat weight
for your budget.

Better Quality, Smaller Size

This choice will give you the highest grade
of colour, cut, and clarity, however you will compromise on the
carat weight or size.

Size Matters

The Biggest Diamond for your money. This choice will suit you
if you are happy to compromise on the quality of cut, clarity
and colour for a larger diamond.


One of the reasons we are so competitive is we don’t hold lots and lots of
diamonds or post lists of stock we can not produce.
At Diamonds by Design we use our 25 years of gemmological experience to source
you the best stone available for your money either from our Australian
Network or numerous genuine ethical suppliers throughout the World.
