The ultimate gift for anyone looking to get engaged or buy a diamond.


Choosing an engagement ring can be hard. But after reading Rock her World, I knew exactly how to find out what my partner wanted for her engagement ring, and she couldn’t be happier.

Richard Rizzo

I don’t often read books like this, but choosing an engagement ring is a big investment and I wanted to make sure I did my research. Rock her World outlined everything I needed to know in an easy to understand way without the complicated industry jargon. Highly recommend it.

Chris Gevaux

This book made the whole process faster, easier, better than I could have ever done myself and Bec loves the ring.

I have known Karl for a while now and been impressed with him both professionally and personally. He has a fantastic ability to really connect with people, whether it's in front of a keynote audience hanging on his every word, or in a one-on-one consultation with a couple discussingone of the most important times and decisions in their life. It's not just his extensive knowledge that puts people at ease, although that really helps! He offers some great insights on how to find your partner's perfect engagement ring using social media. I am stoked to have read his book and can wholeheartedly recommend it to any couples about to start their marriage journey with him.

Having been involved in the wedding industry for 10 years and dressed 2000 grooms I know when I am talking to a Master of their craft. It is their confidence and ability to answer any question with a to the point reply.Karl is at the top of his game and a pillar within the jewellery industry. His book has everything you need to know about buying a diamond or engagement ring. This would have been handy 10 years ago…when I pro­posed to my wife.

Mark Ferguson

As a designer I can say that Karl Schwantes has a comprehensive understanding of diamonds and how to use them in the design and manufacture of exquisite diamond rings second to none. His book, Rock Her World, is the definitive guide to choosing and purchasing the perfect engagement ring for her.

Wendy Makin

Karl delicately explores the subtle intricacies of a man's traditional role before, during and after the Marriage Proposal. The 'cost of an Engage­ment ring' is a taboo subject in polite conversation and too often the price of a diamond is matched directly with one's feelings toward one's future bride. It can be a tricky path to manoeuvre, particularly for those whose only contact with women's jewellery has been buying the odd Mothers' Day gift. Rock Her World successfully demonstrates a fresh angle that will ultimately assist thousands of couples in their memorable jour­ney through the ever booming Wedding Industry of Australia.

Michelle Anderson

Karl's passion for his trade is palpable. If diamonds are a girl's best friend, then Rock Her World will be your best mate if you're looking to impress your better half. Read it or suffer the consequences!

Tim Reid

If you're looking to pop the question to your significant other and want to ensure you're making the right choices, or you simply want to under­stand more about the skill of buying a quality diamond, then you need this book. Karl is one of Australia's experts when it comes to diamonds , and guides you step-by-step through the process to make sure you're get­ting exactly what you're paying for. This book could save you thousands of dollars!

Simon Dell

Why oh why has it taken so long for someone with real expert knowledge to write a specialised book that's targeted to guys planning to pop the big question? By writing this book and removing the smoke and mirrors asso­ciated with purchasing an engagement ring , Karl Schwantes from Xennox Diamonds has armed every young man on bended knee with the knowledge he needs to confidently walk into a jewellery store and choose the perfect ring. This is his chance to shine big-time in the eyes of his beloved and her family (and his own!) and this book makes his job so much easier.

Rhonda Bannister

One of the most important purchases of my life was the engagement ring I bought. Despite the importance of this decision for many people, there's not much advice on the topic of choosing and giving the perfect expression. This is a much needed book from one of the key people in the know.

Daniel Priestley

Karl Schwantes is clearly a man who is seriously passionate about dia­monds and he has taken all of his passion and knowledge and put it into this fantastic book Rock Her World. But this is much more than a book on diamonds, it is a book about proposing, about love, about relationships and about starting married life the right way. A wonderful book written by a one-of-a-kind man.
