Embracing the Mermaidcore Aesthetic with Fine Jewellery

To embody the sparkle of a mermaid, one must delve into the treasure trove of the ocean’s inspirations, a realm we’ve explored extensively through our bespoke creations. Our fascination with the sea’s artistic bounty makes us self-proclaimed connoisseurs of the Mermaidcore trend.

Crafting a piece of jewellery from the ocean’s mythical narrative requires a few key elements:

The Colour of the Ocean’s Depths: In 2024, blue has emerged as the jewel tone of choice, reflecting the sea’s various moods. From the deep, contemplative hues of Tanzanite to the refreshing sparkle of Aquamarine and the vibrant light of Blue Zircon, these gemstones are becoming a mainstay in high-end jewellery collections.

Harmony with Cool Hues: To achieve the quintessential Mermaidcore look, immerse yourself in a sea of cool tones. These colours act as a sanctuary, offering a sense of escape to the wearer. Complement these with understated greys and warm neutrals like peach, light pink, and yellow to add a multidimensional aspect that mirrors the ocean’s vast palette.

The Fluidity of the Sea in Form: Embrace shapes that reflect the organic, flowing nature of the underwater world. Reject the rigidness of straight lines and sharp edges in favour of the soft curves found in seashells, starfish, and aquatic flora. These elements should be woven into the design thoughtfully to evoke the essence of the sea.

Subtle Sophistication in Design: While capturing the essence of Mermaidcore, it’s crucial to balance literal marine representations with elegance and refinement. Avoid designs that are too on-the-nose to maintain a chic and sophisticated allure. Bespoke jewellery should be a nuanced art, after all.

Trust in Craftsmanship: Lastly, trust in your designer’s vision is paramount. A good designer will navigate the balance between thematic inspiration and timeless design, ensuring your mermaid dreams are brought to life with finesse and expert craftsmanship.

Gemstone Selection for Crafting Mermaid-Inspired Jewellery

If the allure of mermaid-inspired jewellery captivates you, then you’re likely to be enchanted by Opals, Paraíba Tourmalines, Pearls, Sapphires, Blue Zircons, Tanzanites, and Aquamarines. Each of these gemstones carries a piece of the ocean’s mystery and beauty. Let’s dive deeper into their unique qualities:


Opals stand as a testament to the unique beauty that nature can create, unmatched in their diversity and allure. Each opal is a singular masterpiece, formed from the remnants of ancient rains that permeate the arid landscapes of places like Australia’s Outback. This rainwater, laden with silica, seeps into the deep crevices of the earth, where it eventually solidifies into the opal’s precious form.

The magic of opals lies in their ability to diffract light, creating a mesmerising play of colours that dance across the gemstone. This phenomenon, known as the “Play of Colours,” showcases a vibrant spectrum that can include every hue imaginable, making opals a symbol of the rainbow’s natural beauty.

Opals are celebrated not just for their breathtaking appearance but also for their versatility in jewellery making. They can be paired with a variety of other gemstones to craft pieces that are truly mermaid-inspired, embodying the ethereal and vibrant essence of the sea. With their unique beauty and the ability to represent the full colour spectrum, opals are indeed one of the most enchanting and precious gemstones available, perfect for anyone looking to capture a piece of the ocean’s magic.

Envision the boundless expanse of the ocean and the tranquility of clear skies; blue embodies the essence of infinity and the very essence of life, offering a serene and calming effect. Paraíba tourmalines, with their radiant blue hues, infuse this serene essence into the realm of jewellery.

Discovered in the lush landscapes of Brazil’s Paraíba state, from which they derive their name, these tourmalines present an electric blue that mirrors the pristine beauty of tropical waters. Their discovery marked a revolution in the gemstone world, thanks to their unique and vibrant neon blue and green colours that stand unmatched by any other gem.

Paraíba tourmalines are distinguished members of the tourmaline family, renowned for their diverse and beautiful colour range. Yet, it’s their neon blue hues that set them apart, making them among the most valued and sought-after gems in the market.

The allure of Paraíba tourmalines is not solely due to their extraordinary colour. Their rarity significantly enhances their value, making large, high-quality specimens considered as collectibles or investment-worthy jewels. This combination of unique coloration and scarcity ensures that Paraíba tourmalines continue to captivate and charm, embodying the unspoiled beauty of the natural world in each gemstone.

Pearls are the quintessence of treasures born from the ocean’s depths, making them an unmistakable choice for embodying the mermaid-inspired trend.

Originating from the heart of marine oysters and freshwater mussels, pearls are organic jewels formed as a natural defense against intruders. When an external element invades their sanctum, these mollusks coat the irritant with layers of nacre, the iridescent substance also known as mother of pearl, creating a protective barrier. This process results in the birth of a pearl, a gemstone synonymous with elegance and sophistication.

Revered for their timeless grace, pearls have cemented their status as a perpetual icon in the world of jewellery. Their allure lies not just in their ethereal glow and soft lustre, which capture the light in a way that mimics the gentle shimmer of a rainbow, but also in their versatility. Pearls can stand alone, radiating beauty in a simple, classic strand, or they can be paired with other gemstones to create striking contrasts and compositions.

Imagine the harmony of pearls with the electrifying blue of Paraíba tourmalines – a combination that epitomises the essence of “mermaidcore.” Such pairings highlight the adaptability of pearls, proving that they can seamlessly blend with the vibrant hues of other gems to craft pieces that are both enchanting and deeply rooted in the lore of the seas.

Blue Zircon

Zircon, cherished by collectors for its vibrant spectrum of colours, owes its dazzling array to trace elements like chromium and iron, which imbue the gemstone with a kaleidoscope of hues ranging from yellow and brown to orange and red. Among these, the most venerated shade is undoubtedly blue, a colour so sought after that it accounts for 80 percent of all zircon sales, commanding the market’s highest premiums.

What sets zircons apart, particularly the blue variety, is their remarkable sparkle. This brilliance is largely attributed to their high refractive index, which measures how light bends and breaks into spectral colours as it passes through the stone, similar to a kaleidoscope. This optical property results in a captivating display of rainbow hues, magnificently showcased by the gem’s faceting.

Blue zircons are treasured not only for their enchanting appearance but also for their adaptability across different jewellery styles. Their historical significance, coupled with exceptional lustre, refractive qualities, and dispersion, offers a brilliance that rivals even the most prestigious gemstones. This combination of characteristics renders blue zircons as exquisite choices for those seeking to incorporate a touch of whimsy and the mesmerising beauty of the ocean’s depths into their jewellery collections.

Unlike the age-old mysteries surrounding the first encounters with emeralds or rubies, the discovery of tanzanite is a well-documented marvel of the 20th century. This gemstone captivates with its unparalleled deep indigo hue, a colour that instantly draws the mind to its beauty. However, the allure of tanzanite extends beyond its mesmerising colour to its origin, exclusively found in Tanzania, lending the gem its name and a narrative of rarity and geographical singularity.

The exclusivity of tanzanite, sourced solely from its native soil, underscores its exceptional rarity. Esteemed to be over a thousand times rarer than diamonds, tanzanite’s scarcity elevates its status in the gemstone realm. This exotic gem exhibits a range of colours from deep purple and luminous violet to lush blue. Its unique attribute of pleochroism showcases different colours from various angles, adding to its mystical charm. Coupled with high clarity and an enchanting lustre, tanzanite stands out as one of the most sought-after jewels today.

Tanzanite is often celebrated as the stone of transformation, imbued with potent mystical energies for those inclined to believe in its metaphysical properties. This aspect, along with its visual splendour, makes tanzanite a prime choice for crafting jewellery that echoes the enchanting essence of mermaids and the deep sea’s mysteries. For aficionados of mermaid-inspired aesthetics, tanzanite’s rich colours and storied background offer the perfect touch of otherworldly beauty and allure.

Aquamarines are among the most cherished and valued gemstones in contemporary times, revered for their unparalleled beauty and the serene tranquility they embody. These gemstones are a reflection of calm seawaters, with every aspect of their being deeply intertwined with the essence of the ocean. Their name, derived from the Latin “marina,” directly translates to “of the ocean,” further solidifying their connection to the marine world.

Enshrouded in ancient lore, aquamarines are believed to possess the power to transform foes into friends, as symbolised by the legend of a frog carved from aquamarine. These gemstones are also intertwined with mermaid myths, where it’s said that sirens guarded aquamarines in their underwater vaults, offering them as protective talismans to sailors facing tempests.

What sets aquamarines apart is their exceptional clarity, which imparts a sense of purity and is highly sought after in gemstones. Their availability in a broad range of sizes and forms makes them versatile for crafting exquisite pieces of jewellery. The captivating blue hue and lustrous sheen of aquamarines have ensured their continuous rise in popularity and esteem.
