Ruby Price & Value: What a Ruby Costs and Why

A ruby’s price is driven mainly by its colour, clarity, cut and carat weight — and most of all by whether it’s a natural (mined) ruby or a created (lab-grown) ruby. Created rubies offer the same vivid colour and durability for a fraction of the cost, which is why they’re so popular for everyday jewellery. Here’s a clear, honest breakdown of what you’re paying for.

What Determines a Ruby’s Price

Like all coloured gemstones, ruby is valued on the “4 Cs”, with colour leading the way:

• Colour – the biggest factor. The most valued ruby is a rich, vivid red (often called “pigeon blood”). Too light leans pink; too dark dulls the glow.
• Clarity – fewer visible inclusions means a cleaner stone and higher value. Most rubies have some natural inclusions.
• Cut – a good cut maximises colour and brightness; a poor cut leaves a stone looking flat.
• Carat – larger rubies are rarer, so price per carat rises sharply with size, particularly for natural stones.

Created vs Natural Ruby: The Biggest Price Difference

The single largest factor in what you pay is whether the ruby is natural or created:

• Natural ruby is mined from the earth. Fine natural rubies are rare and can be very valuable, which is reflected in the price.
• Created ruby is grown in a lab. It is real ruby — chemically and physically the same — with the same hardness (9 on the Mohs scale) and vivid colour, but it costs significantly less because it isn’t constrained by mining and rarity.

For most shoppers wanting a beautiful, durable ruby for everyday or gifting, created ruby delivers the look and longevity at a far more accessible price. To understand the stone in depth, see our complete ruby guide.

A Note on Ruby as an “Investment”

You’ll sometimes see ruby described as an investment. While exceptional natural rubies can hold or grow in value, everyday ruby jewellery should be bought for what it is — a beautiful, meaningful piece to wear and treasure — rather than as a financial asset. We think that’s the healthiest way to enjoy it.

Getting the Best Value

• Prioritise colour over size — a smaller, vividly red ruby often looks better than a larger, dull one.
• Consider created ruby for the best colour-to-price ratio.
• Choose a quality setting — 925 sterling silver protects the stone and lasts, without the premium of solid gold.
• Buy from a clear, honest seller who states whether each stone is created or natural.

Frequently Asked Questions

What affects the price of a ruby?

A ruby's price is set mainly by colour (the biggest factor), clarity, cut and carat weight, and above all by whether it is a natural (mined) or created (lab-grown) ruby.

Why is created ruby cheaper than natural ruby?

Created ruby is grown in a lab rather than mined, so it isn't limited by rarity. It is real ruby with the same colour and hardness, but costs significantly less than a comparable natural stone.

Is a more expensive ruby always better?

Not necessarily. Colour matters most - a smaller, vividly red ruby can look better than a larger, duller one. Buy the stone that looks best to you within your budget.

Is ruby a good investment?

Exceptional natural rubies can hold value, but everyday ruby jewellery is best bought to wear and treasure rather than as a financial investment.
