The Nerina Pendant

Katie Mardlin — Thu, 29 Jan 2026 18:35:13 +0000

Named after the Nereids—the sea nymphs of ancient lore—this piece was born from a desire to bring the serenity of the ocean to your everyday wardrobe. Whether the coast is basking in its signature golden glow or tucked away under a rare winter storm, the Nerina serves as a constant connection to the shore. It is a piece for the woman who finds luxury in nature and beauty in the unconventional.

Gemstones: Premium Natural Moss Agate with seaweed-like dendritic inclusions contrasted by a 5mm faceted emerald

Material: Sterling silver with 14k Gold accent
Finish: High-polish bezel setting to maximize light refraction with patination .
Vibe: Sophisticated, organic, and effortlessly chic.

Style Note

Pair the Nerina with a crisp white linen shirt for a classic Marbella lunch, or layer it over a soft cashmere knit for those cozy, rain-swept afternoons at home.

The Champagne Tuesday Ring

Katie Mardlin — Tue, 20 Jan 2026 17:23:21 +0000

“My personal toast to the return of the light.”

I created this ring as the perfect antidote to the winter blues. For me, January on the Costa del Sol is all about that transition from stormy greys to brilliant, golden sunlight—and this 6.5mm Champagne Moissanite captures that shift perfectly.

Moissanite is one of my favourite stones to work with because its “fire” is even more intense than a diamond. In this warm champagne hue, it radiates a sophisticated, honey-toned brilliance every time you move your hand.

The Craftsmanship:

The Stone: I selected a 6.5mm Round Brilliant Moissanite (approx. 1.0ct equivalent) for its exceptional sparkle and warmth.
The Setting: I chose a secure silver rub-over (bezel) setting. I love how the silver frame makes the champagne color “pop” while keeping the stone safe for daily wear.
The Fit: I hand-forged the silver shank with a taper toward the base. I’m a big believer that jewelry should feel as good as it looks, and this design ensures a really comfortable, ergonomic fit.
Size: This ring is a US size 7.5.

Every detail was handcrafted by me in my studio. It’s a little piece of the Spanish sun for you to keep. If you prefer a different size or colour of Moissanite – or in gold vermeil, please get in touch.
