NURTURING RADIANCE
Our Polished Approach

Ritual Of Care
Caring for your ring becomes a ritual - a gentle act of preserving its radiance. To start, mix warm water with mild dishwashing liquid, creating a solution that cradles your diamond in cleanliness. With a soft toothbrush as your companion, give your ring a delicate brush, ensuring every facet gleams with renewed vigor. Rinse it in clean water, let it rest on a cloth, and behold the sparkle.

Embrace The Shine
But we don't stop there – we encourage you to embrace the shine with our Scintilla Diamonds polishing cloth. It's not just a cloth; it's a gesture, a symbol of the care we put into every piece. Gently polish your ring, and as it regains its luster, know that it's not just about the sparkle but the connection you share with your precious gem.

Frequently Asked Questions
What Are Custom-Cut Lab-Grown Diamonds

Custom-cut lab-grown diamonds are expertly created diamonds grown in a controlled environment and shaped to your exact specifications. Unlike standard diamonds, these stones are precision-cut to your desired shape, carat weight, colour, clarity, and cut quality—maximising brilliance and ensuring your jewellery is truly one-of-a-kind. 

At Scintilla Diamonds, our Signature Cut lab diamonds are tailored for clients seeking a personalised and ethical alternative to mined diamonds. Whether you’re designing a custom lab-grown engagement ring in Australia or creating a statement piece, our custom-cut diamonds deliver unmatched sparkle, style, and sustainability.

Can I design my own lab diamond ring

Absolutely, Our Signature Cut bespoke design service allows you to choose your diamond shape, colour, clarity, cut and carat, resulting in a one-of-a-kind ring that reflects your personal story.

Are lab-grown diamonds as durable as natural diamonds

Yes. Lab diamonds have the exact same physical and chemical properties as natural diamonds—making them equally durable, scratch-resistant, and ideal for daily wear.
