Award Winning Designer

This does not mean just looking at cut out photos and second hand pictures or copied drawings, anyone can do that. This means sitting down with an award-winning wedding ring and engagement ring designer who can actually create a diamond solitaire engagement ring design with you while taking you through a creative and enjoyable design process.

100% Handcrafting

We also know that there are many diamond brokers in Sydney and online that claim that the engagement ring they are providing for you is ‘handmade’. In our 50 years’ experience this usually indicates mass or semi-mass production, which simply means that the whole engagement or wedding ring has been cast, or parts of the ring have been cast and then assembled. Compared with truly handcrafted jewellery, this is a definite compromise in build quality and security of your precious white, pink argyle diamond or fancy colour stone. 100% handcrafted jewellery has always and will always ensure and provide the very best gold density and quality with far superior malleability.
