About Us


"With our discerning selection and authentication process you are guaranteed 100% authenticity of every luxury piece of designer jewellery purchased from us."

Established in 2014 we have a Rich History of Selling Pre Loved Diamond Jewellery from Tiffany & Co. and other Luxury Brands. Encouraged by the incredible feedback and support we have received from our customers we quickly became the biggest online Australian re seller of Tiffany & Co. Diamond Jewellery.  Please check out our current collection here.

We are proud of the feedback we receive and encourage you to please check out our feedback both on our website, eBay store, Etsy store and Facebook Page. 

Our Vision:

"Is to preserve the workmanship involved in creating each piece of fine diamond designer jewellery."

Trying to sell a beloved piece of pre-loved jewellery is difficult for an individual.  A jeweller or pawn shop can offer as low as 10% of the retail price of the item.  These items are broken down into base materials and then sold back to the next consumer at full retail.   Our aim is to preserve the original work, save the exquisite beauty and pass on significant savings to you.

Whether you are buying, selling, or consigning a piece of fine diamond designer jewellery, we aim to provide you with the best outcome possible.

As trusted experts in the field we are committed to building our reputation online.  We work hard to provide a safe and simple environment for buying and selling pre-loved fine diamond designer jewellery. 

Our line of Fine Jewellery:

As collectors, one of the biggest challenges we face is that once an item is sold it is gone for good.  It is a common occurrence that we will have more than one customer interested in the same piece and one person will miss out.

We made the decision to launch our own line of 'Catherine Trenton' Diamond Jewellery. Each piece is hand made created out of 18ct Solid Gold with Genuine G/SI1 Diamonds. We are so delighted with the feedback we have been receiving on our our line on our website, Facebook Page, Etsy store, eBay store and on Google Reviews.

The benefit to this our own 'CTJ' jewellery is that we don't have the high overheads associated with a physical shop.  Our customers are able to save significantly off regular retail.

As collectors, we hope that our discerning eye for acquiring beautiful pre-loved jewellery can also be used to design jewellery.

We are so humbled by all of our customers that we have had the honor to deal with.  Many of our customers have become loyal advocates and we are forever grateful to the support, kind words and encouragement that we receive from you all.
