Choosing the Perfect Diamond: What to Consider

Selecting a diamond for your engagement ring in Melbourne is a defining moment in your love story. It’s an experience you’ll remember forever. Every detail matters, from the way it sparkles, to its size and proportions, all the way to its craftsmanship. 

Here’s our expert guide on navigating the brilliant world of diamonds, as we delve into what to consider when choosing the perfect diamond for your engagement ring. Ensuring that your diamond choice is timeless and undeniably exquisite. 

The Diamond Shape 

Each diamond shape carries its own distinct character, offering a different expression of brilliance and elegance. The diamond cut affects its style, the ways in which the diamond captures light and their distinctive timeless beauty.

• The Round Brilliant Cut is the most iconic, celebrated for its unmatched sparkle and perfect symmetry. 

• The Oval Brilliant Cut elongates the finger with graceful brilliance

• The Cushion Brilliant Cut enchants with soft rounded corners and romantic fire. 

• The Emerald Cut reveals a refined hall-of-mirrors effect, emphasising clarity.

• The Princess Brilliant Cut delivers modern brilliance through its square geometry

• The Pear Brilliant Cut blends round and marquise elements into a graceful teardrop silhouette. 

• The Marquise Brilliant Cut is bold and regal, creating the illusion of greater size with its elongated points. 

• The Radiant Cut embodies modern faceting and glittery scintillation. 

• The Heart Brilliant Cut stands as the ultimate symbol of love, crafted for the romantics.

Each diamond shape comes with their own unique factors to consider. At JANAI, our team will guide you through the key qualities to look for, tailored to your chosen shape and what matters most to you.

Type of Sparkle: Fiery Brilliant Cut, Elegant Step Cut or Glittery Radiant Cut

The faceting cut is responsible for the type of sparkle the diamond reflects and its defining style. A brilliant cut diamond, such as the round, oval, cushion, marquise and pear are all crafted to maximize sparkle. Refracting light in a brilliant fiery display that reveals with every movement. In contrast, a step cut, like the emerald or asscher delivers a sophisticated, mirror-like brilliance, emphasising clarity and subtle elegance. Lastly, a radiant cut offers intense fire and sparkle with their distinct faceting for a truly glittery appearance. The choice between the type of fiery sparkle or elegant brilliance is a reflection of personal style.

Size and Proportions: Carat Weight and Measurements

Carat weight and measurements are what determine a diamond’s size. The true beauty of a diamond lies in its proportions, as they dramatically influence the overall effect and measurements of the stone. Elongated diamond shapes, such as ovals, marquises, and pears, often appear larger per carat than a round diamond of the same weight, creating a sense of presence.

A well-cut diamond will always appear larger than its carat weight suggests, with ideal dimensions that balance depth, table size, and crown height. It’s entirely possible that a lower carat weight, yet perfectly proportioned diamond sparkles more magnificently than a heavier, poorly cut stone.

When selecting a diamond, carat weight alone does not tell the full story. It’s essential to view the diamond in person, not only to appreciate its brilliance but also to see how the shape, proportions and carat weight complements your hand. The same carat weight diamond can look strikingly different from person-to-person,  looking either more delicate or more bold on the finger. 

Colour and Clarity

Colour and clarity are key aspects of a diamond’s character, shaping their unique story. Colour is graded on a scale of D-Z, with the most coveted stones being completely colourless (D-F), followed by near-colourless (G-J). Clarity measures the presence of natural inclusions, the tiny internal features that are created during the diamond's formation. While microscopic inclusions are often invisible to the naked eye, they define the stone’s individuality. 

Together, the colour and clarity establish the essence of a diamond and their unique characteristics. At JANAI, our specialist team provides you with detailed information about each diamond’s attributes so you can make an informed decision and choose the stone that feels right for you.

Diamond Certifications: Trust and Authenticity 

It’s essential to select a diamond that comes with a grading certificate, as it guarantees authenticity and provides a precise assessment of the stone’s quality.

In the world of diamond certification, there are three laboratories that truly set the standard: Gemological Institute of America (GIA), Gem Certification & Assurance Lab (GCAL), and International Gemological Institute (IGI). These globally respected institutions independently assess millions of diamonds each year, applying exceptionally rigorous grading standards. 

GIA, GCAL and IGI use advanced scientific testing to authenticate every diamond that passes through their laboratories. Expert gemologists carefully examine each stone, producing detailed reports that capture its unique characteristics and quality. A diamond certificate typically outlines the 4Cs (cut, colour, clarity and carat weight)along with the cut grade, including polish and symmetry, precise measurements and proportions, and a clarity map identifying any inclusions.

These grading reports are an essential part of understanding a diamond’s true value. Beyond the sparkle you see with the eye they offer a deeper assurance by defining the craftsmanship, rarity and quality that make each diamond truly exceptional.

Natural or Lab-Grown: Diamond Origins

Today, buyers have the choice between natural diamonds, formed over billions of years deep within the earth, or lab-grown diamonds formed with advanced technologies in modern facilities. 

Despite these differences in origin, lab-grown and natural diamonds are identical in their physical and chemical makeup, and both are graded and certified under the same standards. They display the same range of cut, colour, clarity, and carat, and both achieve extraordinary brilliance and beauty.

Natural diamonds carry rarity, heritage and tradition whilst lab-grown stones offer greater affordability. Both can achieve unmatched beauty, so the choice ultimately reflects personal values as much as aesthetic preference.
