September Birthstone

Physical Properties and Formation

Sapphire, the September birthstone, is a gem variety of the mineral corundum, known for its impressive hardness, rated 9 on the Mohs scale, making it second only to diamond in hardness.

This gemstone is not limited to its iconic blue variety; it also appears in a spectrum of other colours like pink, yellow, green sapphire, and the rare red corundum, which is exclusively classified as ruby due to its deep red hue.

The presence of trace elements such as iron and titanium contributes to the sapphire’s vibrant blue colour through the process of lattice diffusion, while chromium imparts a pink colour to some sapphires.

Sapphires in different colours, including the lesser-known but equally stunning white sapphire, which lacks the colour-causing trace elements, are all considered sapphires due to their shared corundum composition.

White sapphires, offering a clear and often more affordable alternative to diamonds, are particularly valued for their pure, colourless appearance, which is achieved when there is an absence of trace elements that colour other sapphires.

Lapis Lazuli: The Stone of the Heavens

Unlike the structured formation of sapphires, Lapis is a rock, composed mainly of lazurite, which gives it a deep celestial blue, often speckled with pyrite that mimics a starry sky.

Coloured Sapphires

Sapphires are all made of the same mineral, corundum, but the variety of colours beyond the traditional royal blue is due to trace elements present within the crystal structure during their formation. For example:

  • Blue sapphires contain iron and titanium, which are responsible for their deep, rich blue tones.

  • Pink sapphires owe their hue to the presence of chromium, similar to rubies, but in lower concentrations that result in a lighter pink rather than red. They offer a soft yet vibrant alternative to blue sapphire and are popular in more feminine designs.

  • Orange sapphires owe their warm hue to traces of chromium and iron, lending them a fiery glow. When incorporated into jewellery, these gemstones exhibit a vibrant and captivating brilliance, reminiscent of a sunset.

  • Yellow sapphires are coloured by trace amounts of iron that do not contribute to the blue colouring. When set in jewellery, they provide a sunny, cheerful hue that captures the light brilliantly

  • Green sapphires come from a combination of iron and titanium traces within the crystal. These beautiful stones are perfect for pieces that aim for an earthy aesthetic.

  • White sapphire is essentially pure corundum without the presence of trace elements that impart colour to other sapphires. White sapphires are prized for their clarity and subtle beauty, making them a favored choice in various types of jewellery, embodying elegance and sophistication. They are a fantastic alternative to diamonds, providing the same sparkle at a more accessible price point.

Styling September's Birthstones: Sennen Jewellery's Recommendations

Sapphire in Contemporary Jewellery Design

At Sennen Jewellery, we recommend sapphire for its exceptional hardness and vibrant colours, making it a top choice for engagement rings and other fine jewellery.

The resilience of sapphire ensures it can withstand daily wear, which makes it ideal for settings in rings, earrings and necklaces that are frequently worn.

The ring pictured was crafted by Francesca Stella in Cornwall, and is a one of a kind handmade ring made with Single Origin Mine 18ct gold and a mesmerizing star sapphire.

Lapis Lazuli's Artistic Appeal

We at Sennen Jewellery also adore the artistic appeal of Lapis. Its rich, celestial blue interspersed with golden flecks of pyrite gives each piece a unique, eye-catching appearance. Lapis Lazuli pairs exquisitely with both gold and silver, but in our opinion silver coloured metals really show it off to it's full potential.

We recommend Lapis Lazuli for those seeking statement pieces or artisan jewellery that emphasizes the stone’s mystical and celestial qualities. Whether set in simple silver earrings or a more elaborate white gold necklace, Lapis brings a touch of the heavens or the deep blue sea to any outfit.

Famous and Valuable Sapphire Jewellery

Sapphire, with its deep blue elegance, has been central to numerous legendary jewellery pieces, particularly those associated with British royalty.

The Princess Diana Blue Sapphire Engagement Ring

One of the most iconic pieces of sapphire jewellery is the engagement ring that was given to Lady Diana Spencer by Prince Charles in 1981. This ring features a 12-carat oval blue Ceylon sapphire surrounded by 14 solitaire diamonds, set in 18k white gold.

It was created by the crown jeweller Garrard, and inspired by a sapphire and diamond cluster brooch, a wedding present from Prince Albert to Queen Victoria. This same ring made headlines again in 2010 when Prince William proposed to Catherine Middleton with it, and it is now known as the Duchess of Cambridge's engagement ring, symbolizing royal continuity and capturing the public's fascination.

Queen Elizabeth II’s Sapphire Collection

Garrard's Sapphire Jubilee Brooch

Queen Elizabeth II had an impressive collection of sapphire jewellery, which included the famous Sapphire Jubilee Brooch, a gift to mark her 65 years on the throne. Again made by crown jewellers, Garrard, this piece features a large, 118.88ct royal blue Burmese sapphire surrounded by Garrard's signature diamond cluster settings.

The Queen also owned the Victorian Suite of Sapphire and Diamond, which includes a necklace and earrings originally bought by Prince Albert for Queen Victoria in 1840. This suite was later enhanced with a matching bracelet and ring.

Sapphire remains a favoured precious stone in many collections due to its symbolism of wisdom, virtue, and good fortune.

What is the birthstone for Virgo?

For those born under the zodiac sign Virgo (August 23 - September 22), the primary birthstone is sapphirer. Virgos who are born in August might also resonate with peridot, the traditional August birthstone, known for its shimmering green hues that symbolize strength and vitality.

Sapphire, especially in its blue varieties, symbolizes wisdom, virtue, and holiness, aligning well with Virgo's characteristics of intelligence, meticulousness, and purity.

Which sapphire colour is the most valuable?

Among the various colours of sapphires, the blue variety, specifically the rich, vivid blue sapphires known as "cornflower" or "Kashmir" blue, are generally the most valuable. These sapphires, celebrated as the September birthstone, feature a deep, velvety blue that is highly sought after and often commands the highest prices in the gem market. The rarity and unique saturation of this blue make it especially prized among collectors and enthusiasts.

While the classic blue sapphires are typically the most valuable, other colours like the intense pink sapphire, vibrant yellow sapphires, and the rare green sapphire also hold significant value and appeal. Each of these colours has unique qualities that can attract specific tastes and preferences in jewellery.

White sapphire, though less common, offers a clear, pure alternative that appeals to those looking for something different from the traditional blue.

Regardless of the colour, the worth of a sapphire in any of these hues also depends on its clarity, cut, and carat weight, making each stone unique. As the birthstone for those born in September, sapphires of all shades continue to be a cherished choice for jewellery, representing wisdom and nobility.
