Loose Diamonds

Kalfin Jewellery takes great pride in the quality of the diamonds we use. We have a large selection of loose diamonds in different shapes and sizes to choose from. We can cater for every budget and need that will give you the perfect diamond ring. Our strict selection criteria and direct dealing with the importer ensures outstanding value and quality.

Our sourcing and selection requirements outperform many of the well-known international brands. We refuse to put our hallmark on poorly cut diamonds and diamonds that are below the ‘G’ colour grading and SI-1 clarity grading (100% eye clean). All our loose diamonds must surpass our minimum requirements before they are offered to our clients. All our diamonds are also ethically sourced. When selecting a loose diamond from Kalfin Jewellery, you can be confident that it will be premium quality.

All our stones above 0.30ct are independently certified by GIA (the Gemological Institute of America). With advice and guidance from our diamond experts, we can help you choose the right loose diamond that will complement your design and budget requirements. We will explain the 4C’s and your ability to view and compare our diamonds will provide peace of mind in selecting the right one for you.

We welcome you to arrange an obligation-free consultation at our Collins Street boutique in the Melbourne CBD to explore your choices. You might also like to read our ‘How to Buy Diamonds’ guide.
