Garnet
January
Garnet is the birthstone for January and a gem rich in both colour and meaning. Named from the Latin word for grain—thanks to its resemblance to pomegranate seeds—garnet symbolises love, loyalty, friendship, and trust. It’s long been believed to offer protection, especially during travel, making it a meaningful stone for both sentiment and symbolism.
At Prudence, we love garnet for its strength and spirit—but like all meaningful things, it deserves a little TLC. With a hardness of 6.5 to 7.5 on the Mohs scale, it’s suitable for everyday wear, though we recommend removing it before any heavy lifting (literal or metaphorical). To keep your garnet glowing, clean it gently with warm soapy water and a soft cloth—no harsh chemicals, please. It’s a stone with heart and heritage, and with a little care, it will stay just as radiant as the day you met.

Amethyst
February
Amethyst is the effortlessly elegant cool girl of the quartz family—calm, collected, and quietly radiant. Known for its dreamy violet hues, this gemstone has long been associated with clarity, balance, and inner peace. Ancient Greeks believed it could ward off intoxication (handy!), while today it’s more often embraced for its soothing energy and spiritual grounding.
With a rating of 7 on the Mohs scale, amethyst is reasonably durable, making it a lovely option for regular wear—just not when you're gardening, lifting weights, or wrangling furniture. At Prudence, we recommend treating your amethyst with a little tenderness: avoid prolonged exposure to direct sunlight (it can fade), and keep it away from harsh chemicals. A gentle clean with warm, soapy water and a soft cloth will keep it sparkling beautifully.

Aquamarine
March
Aquamarine is the coastal escape of the gemstone world—light, serene, and impossibly fresh. Its name means "water of the sea," and with those soft blue tones, it’s basically a deep breath in stone form. Traditionally linked to courage, clarity, and calm communication, aquamarine is said to soothe the soul and steady the mind—like a dip in cool, clear ocean water (minus the sand in your swimmers).
On the Mohs scale, aquamarine sits at a 7.5 to 8, meaning it’s fairly tough and well-suited to everyday wear—though, like all fine things, it appreciates a little kindness. At Prudence, we suggest removing your aquamarine jewellery before anything high-impact, and avoiding prolonged heat or harsh chemicals. A soft cloth and warm, soapy water is all it needs to keep that sea-glass sparkle going strong. A stone of ease and elegance, aquamarine is as timeless as it is tranquil.

Diamond
April
The diamond is all about clarity, strength, and enduring beauty. Known as the hardest naturally occurring substance on earth, diamonds rate a 10 on the Mohs scale, making them incredibly resilient and ideal for everyday wear. Symbolizing eternal love, purity, and inner strength, diamonds have long been treasured for both their brilliance and their emotional significance.
At Prudence, we adore diamonds not just for their sparkle, but for their substance. While their hardness makes them scratch-resistant, they’re not invincible—sharp blows or knocks against hard surfaces (like tile or metal) can chip the edges or points, especially on delicate cuts. We recommend storing your diamond jewellery separately in a soft pouch or cloth to avoid scratching other pieces (yes, they’re that tough).
To keep your diamond shining bright, give it an occasional soak in warm soapy water, gently scrub with a soft toothbrush, and pat dry with a clean cloth. A stone as timeless as your story, the diamond is a daily reminder that strength and beauty go hand in hand.

emerald
MAY
Emerald, the birthstone of May, is a symbol of renewal, wisdom, and enduring love. Revered since antiquity, most notably by Cleopatra herself, emerald has long been associated with vitality and elegance. Its rich green hue evokes lush landscapes and new beginnings, making it the perfect companion for those born in the heart of spring.
With a rating of 7.5 to 8 on the Mohs scale, emeralds offer reasonable durability, but their natural inclusions, often referred to as jardin, or “garden” make them more vulnerable to chips or cracks than other stones of similar hardness. These delicate internal features are not flaws, but rather part of the emerald’s unique character and charm.
At Prudence, we recommend wearing your emerald jewellery with considered care. Remove it during manual tasks or high-impact activities, and avoid exposure to heat, chemicals, or ultrasonic cleaning. Instead, gently cleanse with warm, soapy water and a soft cloth.
A gemstone of substance and story, the emerald is a timeless choice for those who appreciate beauty with depth — refined, rare, and quietly powerful.

pearl
June
Pearl, the birthstone for June, is a symbol of elegance, intuition, and timeless femininity. Unlike other gemstones formed deep within the earth, pearls are born of the sea — organic treasures created by oysters and molluscs, which only adds to their mystique and delicate charm.
Their soft iridescence has made them beloved for centuries, associated with wisdom, serenity, and quiet confidence. No two are exactly alike, and this individuality is part of what makes pearls so special.
With a Mohs hardness rating of 2.5 to 4.5, pearls are far softer than most gemstones, which means they require a gentle touch and thoughtful care. At Prudence, we see pearls as the poetry of your collection — best worn mindfully and always the last thing you put on before leaving the house.
Avoid exposing your pearls to perfumes, hairspray, or harsh chemicals, as their natural lustre can dull over time. To clean, simply wipe them with a soft, damp cloth after wearing. Store them separately in a soft pouch or cloth-lined box to protect their surface from scratches or abrasion.
Understated yet captivating, pearls are a quiet luxury — a reminder that beauty doesn’t need to shout to be seen.

Ruby
July
Ruby, the birthstone for July, is bold, passionate, and unmistakably powerful. Known as the “king of gemstones,” ruby has long been associated with vitality, courage, and love that runs deep. Its fiery red hue speaks to the heart — a symbol of intensity, protection, and enduring devotion.
With a Mohs hardness rating of 9, ruby is second only to diamond in durability, making it an excellent choice for everyday wear. Whether set in a striking solitaire or nestled among softer stones, ruby holds its own — both in strength and in presence.
At Prudence, we love ruby for its richness and resilience, but even strong stones deserve care. To keep your ruby radiant, we recommend cleaning it gently with warm, soapy water and a soft brush.
Store ruby pieces away from softer gems to avoid accidental scratches, and remove jewellery before doing anything particularly hands-on (gardening, gym, dramatic DIY moments).
Confident, commanding, and utterly timeless, ruby is for those who wear their passion well.

peridot
August
Peridot, the birthstone for August, is a gemstone of warmth, optimism, and quiet strength. With its soft, sunlit green — often kissed with golden undertones — peridot has long been associated with prosperity, renewal, and emotional clarity. Known by the ancient Egyptians as the “gem of the sun,” this luminous stone carries a lightness that feels both grounding and uplifting.
With a Mohs hardness rating of 6.5 to 7, peridot is moderately durable, but it’s best suited to gentle, considered wear. It can be prone to scratching if knocked or stored carelessly, and high heat or harsh chemicals can cause damage over time.
At Prudence, we recommend treating your peridot pieces with care: remove them before physical work or cleaning, avoid sudden temperature changes, and store them separately from harder stones. To keep their glow soft and clear, clean peridot jewellery with warm, soapy water and a soft cloth — no ultrasonic or steam cleaners, please.
Delicate yet spirited, peridot is a stone that brings a fresh, calming energy to any collection — a quiet celebration of clarity, abundance, and late-summer light.

sapphire
september
Sapphire, the birthstone for September, is a symbol of wisdom, loyalty, and enduring elegance. While most recognise sapphire by its signature deep blue, this remarkable gemstone is found in a full spectrum of colours — from soft peach to vivid yellow, green, violet, and even rare colourless and pink hues. Each shade tells its own story, but all sapphires carry the same sense of quiet strength and timeless allure.
Ranking 9 on the Mohs scale, sapphire is one of the hardest and most durable gemstones, second only to diamond. This makes it an exceptional choice for everyday wear, whether in an heirloom ring or a modern pendant — beautiful, resilient, and made to last.
At Prudence, we love sapphire for its versatility and soul. While it’s a strong stone, we recommend a touch of gentleness to preserve its brilliance. Clean your sapphire pieces with warm, soapy water and a soft cloth, and avoid exposure to harsh chemicals or extreme heat, especially for stones that have been treated or heat-enhanced. Ultrasonic cleaning is generally safe for natural sapphires, but we always prefer the slow, thoughtful approach.
Sapphire is a gemstone of depth — not just in colour, but in meaning. For those drawn to integrity, clarity, and subtle sophistication, it’s a perfect companion. A piece to wear now, and love forever.

opal
October
Opal, the birthstone for October, is a stone of mystery, emotion, and creative expression. Unlike any other gem, opal carries a kaleidoscope of colour within — flashes of violet, green, gold and rose seeming to dance just beneath the surface. No two are ever alike, which makes opal feel deeply personal — a stone for those drawn to beauty that defies convention.
With a Mohs hardness rating of 5.5 to 6.5, opal is softer and more porous than many gemstones, requiring a little extra love. At Prudence, we believe that’s part of its charm — opal asks to be worn mindfully, not mindlessly.
To care for your opal, avoid exposure to harsh chemicals, prolonged direct sunlight, and rapid changes in temperature, which can cause the stone to dry out or craze. We recommend removing opal jewellery before showering, swimming, or doing anything vigorous with your hands. Clean gently with a soft, damp cloth — no ultrasonic or steam, please — and store in a fabric-lined box, ideally with a touch of moisture in the air.
Opal is a reminder that beauty doesn’t always follow rules — it shimmers on its own terms. Mysterious, magical, and never quite the same twice, it’s a perfect stone for the quietly bold.

citrine
november
Citrine, the birthstone for November, is a gem of warmth, energy, and effortless optimism. With hues that range from soft honey to rich golden amber, citrine captures the light and brings with it a sense of joy, abundance, and clarity. Often referred to as the "stone of success" or the "merchant's stone," citrine has been cherished for centuries as a symbol of prosperity and confidence.
Ranking 7 on the Mohs scale, citrine is durable enough for regular wear but still appreciates thoughtful handling. It’s a member of the quartz family, meaning it's relatively resilient but can be scratched by harder stones or dulled by harsh treatment.
At Prudence, we recommend storing your citrine pieces away from sapphires, diamonds, or anything tougher, and avoiding prolonged exposure to intense heat or direct sunlight, which may cause its colour to fade. Clean gently with warm, soapy water and a soft cloth — skip the steam and ultrasonic cleaners for this golden beauty.
Radiant yet grounded, citrine is a stone that brightens any jewellery collection, and any day. For those drawn to light, warmth, and subtle strength, it’s a gemstone that truly glows from within.

tanzanite
December
Tanzanite is a rare and luminous gemstone, celebrated for its velvety violet-blue hues and sense of quiet mystique. Discovered only in 1967 and found exclusively near Mount Kilimanjaro, tanzanite is one of the most recently added birthstones, associated with the month of December. It is believed to promote intuition, transformation, and a deep sense of calm — a stone for new beginnings and soulful clarity.
With a Mohs hardness rating of 6 to 7, tanzanite is moderately durable but more delicate than sapphire or topaz. It’s best worn with care, especially in rings or bracelets where daily wear may expose it to knocks or abrasion.
At Prudence, we recommend setting tanzanite in protective settings and removing it during hands-on activities. Clean gently with warm soapy water and a soft cloth, and avoid ultrasonic or steam cleaning, as heat and sudden temperature changes may cause damage. Store it separately from harder stones to preserve its smooth polish and signature glow.
Elegant, rare, and richly coloured, tanzanite is a gem for those drawn to the extraordinary — subtle yet striking, modern yet timeless.
