Diamonds – The 4C's

Though we work with all precious and semi-precious stones, diamonds are our specialty at MDT Design. Diamonds are judged by four distinct factors known as the 4C's – Diamon Carat Weight, Diamond Colour, Diamond Clarity and Diamond Cut.

Diamond Guild

MDT design are members of the Diamond Guild Australia (DGA), an association which has a reputation for integrity and ethical trade, both within the industry and in the public domain.Argyle Pink Diamonds

DGA members are recognised for only buying diamonds from a guaranteed source, and being Conflict Free.

The term "Conflict Diamonds" is used to describe rough cut diamonds that are mined or stolen to finance armed rebellion against legitimate internationally recognised governments.

DGA members are governed by a strict schedule of constraints in order to avoid the use of misleading terms in regard to the promotion or sale of diamonds.

Australian Argyle Pink and Argyle White Diamonds

We are stockists of both Australian Argyle Pink Diamonds and Argyle White Diamonds and all are mined in Western Australian and therefore are all guaranteed Conflict Free as all our other diamonds are. If you are looking for an all Australian Handmade jewellery peice this is a great option.


MDTdesign are stocklists for Passion8 diamonds.

Passion8 diamonds have three distinguishable factors – perfection in polish, symmetry, and proportion and it is this perfection that is the very hallmark of Passion8 diamonds.

Every Passion8 diamond sold comes with its own unique independent international gemmological laboratory report (certificate) and its own authenticity card. It is also sold with its own Passion8 Hearts and Arrows scope to enable you to view the stunning patterns of hearts and arrows.
