Choosing the perfect round diamond: a guide for couples  


Choosing the perfect round diamond for an engagement ring is a decision that reflects a couple’s unique love story. It’s more than just a sparkling piece of jewellery; it’s a symbol of commitment and the beginning of a lifetime together.

This guide will help you navigate the options available and decide what suits your style and budget.

Choosing Between Lab-Grown and Mined Diamonds 

One of the first decisions couples may face when selecting a round diamond is choosing between a mined or lab-grown stone. Both options have their unique qualities and advantages, and understanding them is key to making an informed decision:

Lab-Grown Diamonds  

A lab-grown round engagement ring is an increasingly popular choice. These diamonds are created in controlled environments using advanced technology, replicating the natural process that forms a diamond. Here’s what you need to know:

  • Quality And Appearance: Lab-grown diamonds are virtually identical to mined diamonds in appearance, hardness, and brilliance.
  • Price: Often more affordable than mined diamonds, lab-grown options can allow you to choose a larger or higher-quality stone within your budget.
  • Ethics: Many couples appreciate that lab-grown diamonds offer a more transparent and controlled origin, avoiding potential issues related to mining practices.

Choosing a lab-grown round engagement ring provides a beautiful and ethical alternative, offering quality, affordability, and peace of mind in alignment with modern values.

Mined Diamonds 

Mined diamonds are formed deep within the Earth over billions of years, and their charisma and traditional appeal continue to enchant many:

Uniqueness: Each mined diamond is one-of-a-kind, with its unique inclusions and characteristics.

  • Value: Mined diamonds often hold their value over time and may be considered an investment.
  • Tradition: Some people prefer mined diamonds to connect to history and the timeless romance they symbolise.

Choosing a mined diamond emphasises tradition and individuality, offering a one-of-a-kind symbol of love that resonates with many couples’ values and aesthetic preferences.

Considerations For Both Lab-Grown and Mined Stones  

Whether choosing a lab-grown or mined diamond, ensure it comes with certification from a reputable gemological laboratory. This certification will verify the diamond’s qualities and attributes.

Your choice between lab-grown and mined stones may also reflect personal values and preferences, such as sustainability or adherence to tradition. By weighing the unique characteristics of lab-grown and mined diamonds, you can align your selection with your budget, values, and desires. Again, it’s a decision that goes beyond mere aesthetics, offering a way to make your engagement ring truly personal and meaningful.

Emphasizing Sustainable Options  

In today’s world, many couples are leaning towards sustainable options for their big purchases. This means considering the stone’s environmental impact and ethical sourcing when it comes to diamonds. Many jewellers offer certifications that ensure the diamonds are sourced responsibly. It extends to reducing harmful mining practices, supporting fair labour conditions, and contributing to community development.

By seeking out sustainable options, couples can align their purchase with their values and make a positive impact. Whether choosing a lab-grown diamond or a mined stone with a transparent and ethical origin, prioritising sustainability adds another layer of meaning to this significant symbol of love.

Evaluating The Four C’s: Cut, Colour, Clarity, And Carat  

When selecting a round diamond, understanding the Four C’s is essential. These characteristics form the standard criteria used to grade and evaluate diamonds. You may start delving into each aspect, so you know what to look for:

  • Cut: When considering a round diamond, the cut is paramount. A well-cut diamond will exhibit a high level of brilliance. Look for cuts rated as ‘excellent’ or ‘very good’ for the best effect.
  • Colour: Diamond colour ranges from D (colourless) to Z (light yellow or brown). While grades D to F are colourless, they can be costly. Grades G to J are near-colourless and typically undetectable once set in a ring. Aiming for a grade between G and J offers a stunning appearance at a more approachable price, balancing beauty and budget.
  • Clarity: Diamond clarity refers to the absence of inclusions and blemishes. Opt for a clarity grade of Very Slightly Included 2 (VS2) or Slightly Included 1 (SI1) to balance appearance and cost.VS2 indicates slight inclusions that are difficult to see under 10x magnification by a trained gemmologist. On the other hand, SI1 means the diamond has inclusions more easily seen under 10x magnification but still may be invisible or barely visible without magnification, depending on the size and placement of the inclusions.
  • Carat: The Carat weight reflects the size of the diamond. The larger a diamond is, the more valuable it is. But remember, bigger isn’t always better. Focus on the overall quality of the diamond, not just its size.

By understanding the Four C’s and considering them in your selection, you’ll be equipped to find a diamond that captures the beauty and essence of your relationship.

Shopping With Confidence 

Take the time to research and compare various jewellers and their offerings. Look for transparent pricing and clear information about the diamonds’ attributes.

Set a budget that feels comfortable. There’s no need to overspend on a ring; what matters most is the thought and love that goes into choosing it. Don’t hesitate to consult with a professional jeweller. Their expertise can guide you in selecting one that meets your expectations and stays within your budget.

Finding the perfect round diamond is a journey that combines personal taste, budget considerations, and an understanding of the qualities that make a diamond truly shine. By following this guide, you’ll be well on your way to selecting a ring that symbolises your love and commitment, reflecting your unique story as a couple. Whether you opt for a lab-grown round engagement ring or prioritise sustainable options, the key is to choose with care and confidence.
