INFORMATION ON DIAMONDS, GEMSTONES, AND ETHICAL SOURCING
I believe that knowing the story behind your jewellery is important. Many of the diamonds and gemstones I use have been collected over the years, and for some, their exact origins aren’t always known. These stones have become part of my collection through years of sourcing, creating, and sometimes inheriting from trusted colleagues in the industry.
Moving forward, I do my best to work with suppliers who are committed to ethical and responsible sourcing, and I’m always happy to share what I know about any particular stone. If you have questions about a piece or want to know more about how I source my materials today, please just ask—I’m here to help and be as transparent as possible.

Diamond Education FAQ'S
Here, we answer common questions to help you understand natural and lab grown diamonds, grading, sourcing, and more.
If you’d like to discuss your options in person, we’re always happy to arrange a private consultation.
A natural diamond is a gemstone formed deep within the earth over billions of years, under intense heat and pressure. Made almost entirely of crystallised carbon, these stones are brought to the surface by ancient volcanic activity and then mined. Once cut and polished, their natural brilliance and durability make them a classic choice for fine jewellery.
Yes, lab grown diamonds are real diamonds. They are created in laboratories using advanced technology that replicates the natural conditions under which diamonds form. Lab grown diamonds have the same chemical, physical, and optical properties as natural diamonds—the only difference is their origin.
Lab grown diamonds are produced using two main methods:
- High Pressure High Temperature (HPHT):** This process mimics the natural way diamonds form by applying high pressure and heat to carbon.
- Chemical Vapour Deposition (CVD): This method grows diamonds layer by layer inside a chamber using carbon-rich gas.
Both techniques create diamonds that are visually and structurally identical to those found in nature.
To the naked eye, no—lab grown and natural diamonds look the same. Even under magnification, they are nearly impossible to distinguish. Only specialised laboratory equipment can reliably tell them apart. Certified lab grown diamonds are often laser-inscribed for identification.
Diamonds are graded using the Four Cs, which help determine their quality and value:
- Cut: Refers to how well the diamond is shaped and faceted. A well-cut diamond will reflect light beautifully, creating sparkle and brilliance.
- Colour: Diamonds are graded from D (colourless) to Z (light yellow or brown). The less colour, the rarer the diamond.
- Clarity: Measures the presence of natural inclusions or blemishes. Most are microscopic and not visible without magnification.
- Carat: Indicates the diamond’s weight. One carat equals 0.2 grams. Two diamonds of the same carat weight may look different in size depending on their cut.
There are many beautiful diamond shapes available. Some of the most popular include:
- Round Brilliant
- Oval
- Emerald
- Pear
- Marquise
- Princess
- Heart
We also enjoy working with unique and alternative shapes, especially for bespoke designs.
Diamond certification is an independent assessment of a diamond’s quality, carried out by recognised gemmological laboratories. The certificate details the diamond’s Four Cs and other characteristics. Reputable labs include:
- Gemological Institute of America (GIA)
- Antwerp World Diamond Centre (HRD)
- American Gem Society (AGS)
- Diamond Certification Laboratory of Australia (DCLA)
Certification provides confidence in what you’re buying and can be important for insurance and resale.
A conflict-free diamond is one that has not been used to finance armed conflict. The Kimberley Process Certification Scheme was established in 2003 to help prevent conflict diamonds from entering the market. All our diamonds are sourced from trusted suppliers who guarantee compliance with the Kimberley Process.
Natural diamonds can have positive impacts, such as supporting local communities through employment, infrastructure, and education. However, environmental and social standards can vary between mines and countries. We work only with suppliers who prioritise responsible sourcing and provide written assurances of ethical practices.
- Unique Origin: Each natural diamond is a product of the Earth’s history, formed over billions of years.
- Rarity: Gem-quality natural diamonds are geologically rare.
- Tradition: Natural diamonds have a long-standing place in cultural and family traditions.
- Established Market: There is a well-established global market for natural diamonds.
- Things to consider: Mining can have environmental and social impacts, and natural diamonds are generally more expensive than lab grown options.
- Identical Properties: Lab grown diamonds are chemically and visually the same as natural diamonds.
- Affordability: They typically cost less than natural diamonds of the same size and quality.
- No Large-Scale Mining: Lab diamonds are created in controlled environments, without traditional mining.
- Access to Larger Stones: Your budget may stretch further with lab grown options.
- Things to consider: The environmental impact depends on the energy source used in production, and lab grown diamonds are not as rare as natural ones. Their long-term resale value is still developing.
Lab grown diamonds do not require traditional mining, but their sustainability depends on the energy used during production. Some laboratories use renewable energy, while others rely on fossil fuels. We’re happy to discuss the sourcing and environmental credentials of any diamond you’re considering.
Natural diamonds have historically retained value more consistently than lab grown diamonds, but resale markets can fluctuate for both. We recommend choosing a diamond for its meaning and beauty, rather than as a financial investment.
The best choice depends on your personal values, style, and budget. Some people prefer the rarity and tradition of natural diamonds, while others appreciate the accessibility and innovation of lab grown stones. Both are beautiful and durable options for fine jewellery.
We offer private, appointment-only consultations at our Northern Rivers studio. During your visit, we’ll guide you through the options, answer your questions, and help you compare diamonds in person—including under magnification. If you’re unable to visit in person, we’re also happy to meet with you via Zoom, Google Meet, or your preferred video platform. Our aim is to help you find a diamond that aligns with your values and vision.
Our diamonds—both natural and lab grown—are sourced from reputable suppliers who comply with the Kimberley Process and prioritise ethical practices. Natural diamonds may come from regions such as Africa, Canada, Australia, or Russia, while lab grown diamonds are produced in certified laboratories.
In addition, many of the diamonds and gemstones in my own collection have been gathered over the years, and for some, their exact origins aren’t always known. These stones have become part of my collection through years of sourcing, creating, and sometimes inheriting from trusted colleagues in the industry.
Yes, absolutely. We encourage you to view and compare diamonds in person during your private appointment. This allows you to appreciate their individual qualities and make an informed choice.
