Frequently Asked Questions
What should I look for when buying a loose diamond in Australia

Focus on the 4Cs: Cut, Colour, Clarity, Carat Weight—all certified. Partner with a jeweller offering guidance, transparency, and third-party certification. 

The 4Cs of a diamond are the universal standard used to evaluate a diamond's quality and value. They are: 

1. Cut: This refers to how well a diamond has been shaped and faceted. A well-cut diamond reflects light beautifully and has more sparkle. 

2. Colour: Diamonds come in a variety of colours, but the most valued are those that are colourless or near-colourless. The colour scale ranges from D (colourless) to Z (light yellow or brown). 

3. Clarity: This measures the presence of internal or external flaws, known as inclusions and blemishes, respectively. Diamonds with fewer imperfections are more valuable. 

4. Carat Weight: This indicates the size of the diamond. One carat is equivalent to 0.2 grams, and larger diamonds are typically rarer and more valuable. Although size and weight aren’t everything, a smaller diamond with high ratings in the 4Cs can be worth more. 

Understanding the 4Cs helps in making informed decisions when purchasing diamonds, as each aspect contributes to the overall beauty and worth of the stone. 

Are lab-grown diamond rings available in Australia

Can I design a custom engagement ring in Australia

Why choose a loose diamond over a pre-set ring?

You gain full control over the diamond’s specifications and can create a ring that reflects your unique style.

Does Scintilla Diamonds offer pre-set rings

Scintilla Diamonds is excited to introduce our new collection of pre-set diamond rings! These stunning pieces are designed to offer elegance and simplicity for those seeking a beautiful engagement or special occasion ring without the hassle of custom selection. Each ring features carefully selected diamonds set in exquisite designs, ensuring quality and brilliance. Stay tuned to our website for preset rings!

Are custom engagement or wedding rings more expensive

Not always. Our bespoke process is flexible and budget-aware, without compromising quality or craftsmanship.

What’s the difference between natural and lab-grown diamonds

Both have the same chemical structure and brilliance. Natural diamonds form over billions of years underground, while lab-created diamonds are grown using advanced technology in a matter of weeks—making them more sustainable and affordable.Both have identical chemical and physical properties.

How should I care for my diamond jewellery

To care for your ring, clean it gently using warm water and mild soap, along with a soft cloth or a toothbrush for delicate areas. After cleaning, polish it with the Scintilla Diamonds care cloth to maintain a lasting shine. Make sure to store the ring in the Scintilla Diamond-lined ring box. It's important to avoid abrasive cleaners or ultrasonic machines unless they are specifically approved for your type of metal and gemstones.

What’s the average time for a custom engagement ring

Typically, 6-8 weeks, depending on design complexity and diamond sourcing.
