What Diamonds Do We Buy?

We purchase selected diamonds that meet current market demand. Factors we consider include:

  • Diamond size (carat weight)
  • Diamond shape
  • Colour and clarity grades
  • Cut quality
  • Laboratory certification
  • Current wholesale and resale market demand

As market conditions change, not all diamonds will be suitable for purchase. Our team will assess your diamond and explain the factors influencing its value.

Certified Diamonds Preferred

To assist with the evaluation process, we recommend bringing any available documentation, including:

  • GIA certificates
  • IGI certificates
  • HRD certificates
  • Previous valuations
  • Insurance replacement valuations
  • Purchase invoices or receipts

Having certification available helps us assess your diamond more efficiently and accurately.

How Our Diamond Assessment Process Works

Step 1 – Visit Our Adelaide Office
Simply bring your diamond or diamond jewellery to our Adelaide CBD office. No appointment is necessary.

Step 2 – Professional Evaluation
Our trained staff will inspect your diamond and review any certificates or valuations provided.

Step 3 – Market Assessment
We evaluate current market demand and determine whether we are able to make an offer for the diamond.

Step 4 – Receive an Offer
If your diamond meets our purchasing criteria, we will provide a competitive offer on the spot.

There is absolutely no obligation to accept.

Selling Diamond Jewellery

We assess both loose diamonds and diamond jewellery, including:

  • Diamond engagement rings
  • Diamond wedding bands
  • Diamond earrings
  • Diamond pendants
  • Diamond tennis bracelets
  • Loose certified diamonds

If your item also contains gold, platinum, or other precious metals, these components will be assessed separately and included in the overall offer where applicable.
