Ruby - July Birthstone

Ruby stands alongside diamond, sapphire, and emerald as one of the four precious gemstones — a category that has remained consistent across cultures and centuries. Its red is unlike any other stone: intense, warm, and alive in a way that has made it one of the most desired gemstones in the world throughout recorded history. For anyone born in July, it's a birthstone with genuine weight behind it.

What does ruby mean?

Ruby has been called the king of gemstones since antiquity. Ancient Sanskrit texts referred to it as ratnaraj — king of precious stones. In Burma, warriors implanted rubies beneath their skin before battle, believing the stone would make them invincible. Medieval Europeans believed ruby darkened in colour to warn its wearer of danger. Across cultures and centuries, the themes are consistent: passion, courage, protection, and vital force.

Today ruby's symbolism centres on love, strength, and prosperity. It's a stone associated with deep emotion and commitment — not the gentle affection of rose quartz, but something fiercer and more enduring. It's also connected to confidence and the courage to act, which makes it particularly fitting for the bold, driven character of both Cancer and Leo — the two signs that run through July.

Why is ruby July's birthstone?

Ruby's connection to July comes through its ancient association with the sun and with the signs of Cancer and Leo. Cancer (21 June – 22 July) and Leo (23 July – 22 August) between them cover the month, and both have ties to ruby's qualities — Cancer's deep emotional intensity and Leo's fiery, confident energy both resonate with what ruby represents. In ancient astrological traditions, ruby was the stone of the sun itself, and July — at the height of summer in the northern hemisphere — is the sun's month.

The stone itself — what to know

Ruby is the red variety of corundum — the same mineral family as sapphire. What makes it red, rather than blue or any other colour, is the presence of chromium within the crystal structure. The depth and purity of that red determines quality: the most prized rubies show a rich, saturated crimson known in the trade as "pigeon's blood" — a pure red with a slight blue undertone, free of orange or brown.

The finest rubies in the world come from Burma (Myanmar), where the Mogok Valley has produced exceptional stones for centuries. Thai, Sri Lankan, and Mozambican rubies are also commercially significant, each with slightly different colour characteristics. Mozambican rubies in particular have emerged in recent decades as some of the finest available.

Ruby scores a 9 on the Mohs hardness scale — second only to diamond — making it one of the most durable gemstones in existence and genuinely suited to everyday wear in any jewellery format. A fine ruby is also exceptionally rare: a top-quality ruby of significant size commands higher prices per carat than an equivalent diamond, making it one of the most valuable gemstones by weight.

Some rubies display a phenomenon called asterism — when cut as a cabochon (a smooth, domed shape rather than faceted), a six-pointed star appears to float across the surface. These star rubies are among the most spectacular natural gemstone effects.

Ruby and healing — what people believe

In crystal traditions, ruby is strongly associated with the root chakra — the energy centre of grounding, physical vitality, and security — and the heart chakra, connecting its grounding energy to love and emotional courage. It's described as a stone that activates and energises: useful for periods of low motivation, for overcoming fear, or for bringing sustained passion to something that matters.

How to wear ruby jewellery

Ruby's red is strong enough to anchor any piece — it doesn't need elaborate metalwork to make an impression. Gold is the traditional pairing, and with good reason: yellow gold deepens the warm tones in the stone, creating a richly luxurious combination. Rose gold softens the contrast slightly. Silver brings ruby's colour forward more starkly, which works well in cleaner, more modern settings.

As a necklace, a ruby pendant at collarbone length makes a clear statement without being overdressed. As earrings, the colour frames the face with warmth. Browse our ruby jewellery collection and the full July birthstone range, all handmade in our Chester studio.
