Embracing Variety: Rubies come in a range of sizes, allowing you to find the perfect gem for your desired jewellery piece. From delicate accent stones to statement centrepieces, there’s a ruby size to suit every style and occasion. Whether you prefer a modest and subtle touch or a bold and eye-catching display, the versatility of ruby sizes ensures endless possibilities.
Carat Considerations: When it comes to rubies, carat weight plays a crucial role in determining their value. As with other gemstones, larger rubies tend to be rarer and more valuable. However, it’s important to note that carat weight alone doesn’t determine a ruby’s worth. Factors such as colour, clarity, and cut also significantly impact the gem’s overall desirability and price.
Balancing Size and Quality: While larger rubies may be highly sought after, it’s essential to strike a balance between size and quality. Opting for a slightly smaller ruby with exceptional colour and clarity can often result in a more visually stunning gemstone. The intense red hue and inner glow of a high-quality ruby can surpass the impact of a larger stone with lesser qualities.

Cracking the Code:
Which colour of ruby holds the highest value?
In general, rubies with a vivid red hue, known as “pigeon’s blood” red, are highly coveted and command the highest prices in the market. These rubies should have a deep, pure red colour with a hint of blue and excellent clarity. Additionally, the origin of the ruby can impact its value, with stones from certain regions, such as Burma or Mozambique, often being highly sought after.
