Into the Deep: Ocean-Toned Colour Palettes from My Portfolio
Living in Devon, the sea is never far away — and it’s never far from my mind when I’m designing either. Blue, teal, green, that impossible turquoise you only get on a really good day… these colours have woven their way through my work for years. So here’s a proper dive into my favourite ocean-toned designs, and the gems behind them for all you treasure loving mermaids out there…
My Favourite Ocean-Toned Gems
Blue, Teal & Green Diamonds
Not the sparkly white kind — I’m talking rich teals, olive greens and vivid blues.
The coloured diamonds I use are often heat treated, and I think it’s worth saying plainly: these are real mined diamonds. The treatment doesn’t change what they are — it just unlocks colour the stone was always capable of. The result are vivid teals, bright blues and stunning greens…that’s a yes from me!
Blue/Green Sapphires
The blue sapphire is the benchmark for a reason. You’ve got the classic cornflower blue that everyone thinks of when you mention a sapphire but they also come in a whole spectrum of blue shades and sometime with magical overtones or zoning of purples, yellows and other sumptuous shades! That said, green sapphires deserve far more attention than they get — they range from pastel green to teal to sage and forest greens and are often underrated! I love Sapphires not only for their beautiful colours but hey are also really hardwearing at a 9 on the Mohs scale, which matters a lot when someone’s going to wear something every day.

Beryl
Emeralds, morganites & aquamarines (and more!) are all part of the Beryl family of gems. In fact when a stone isn’t saturated enough in colour to be classed as an emerald it may be referred to as simply ‘Beryl’. Whilst emeralds and aquamarines are amongst my favourite types of Beryl they may struggle to take daily knocks happily, and they deserve to be seen at their best rather than gradually losing their sparkle - so, if you save them for occasions they’ll reward you for it!

Tourmaline
Most people think of watermelon shades when they think of tourmaline like hot pinks and olive greens — but tourmaline has other exciting shades too! Vivid turquoise, teal, deep blue-green indicolite tourmaline - it’s a stone that never stops surprising me, and I’m always hunting for interesting ones. (More on the very best tourmaline in the world at the end of this post…)

Topaz
This is a more budget-friendly hero of the blue gem world. Sky Blue is pale and fresh, Swiss Blue is bright and clear, London Blue is deep and steely. If you want impact without the spend of sapphire, topaz is your friend.

Coveted Shades: Cornflower Blue Sapphires
If blue sapphire is ‘the classic’, cornflower blue is ‘the blue’. That pure, bright, perfectly saturated medium tone — not too dark, not too pale — is what the entire gem industry has collectively agreed is the pinnacle. Kashmir cornflower blues are the most coveted and expensive coloured gemstones in the world whilst fine Ceylon examples aren’t far behind.
Here are a few examples of design I have made featuring this gorgeous shade of sapphire…

Blue Stone Trilogy Rings
My most reliable crowd-pleaser, without question: a blue gemstone centre, two white diamonds either side. Simple, and it works every single time. The diamonds don’t compete — they frame & make the blues sing! If blue gems are calling to you and you’re not sure where to start, start here.

Cushion Cut Blue Stones
The cushion cut is one of my favourite gem cuts — soft square shape, beautifully rounded corners and gorgeous for showing off colour in a deeper stone. Opt for a portrait orientation to create a classic and elegant look or rotate it 45 degrees to sit point-up in a diamond orientation and suddenly the whole thing feels contemporary and unexpected! Enjoy a couple of my favourite examples of cushion cut blue gemstones from my portflio below…

Turquoise Shades — and the Stone I’ve Coveted for Years
The stones that can’t decide between blue and green are often the most interesting. Indicolite tourmaline lives right in that territory but I’ve worked with diamonds with the most beautiful shades of turquoise too.
But the one I’ve wanted to wear for years — the one that has stubbornly stayed at the top of my wish list — is Paraiba tourmaline. Discovered in Brazil in the late 1980s, Paraibas contain copper, which produces a neon blue-green that genuinely seems to glow from within! There’s nothing else like it in the gem world. My problem? They are spectacularly, heartbreakingly expensive! We’re talking tens of thousands per carat for the finest stones. Sigh…maybe one day - I’ll keep buying lottery tickets!
In the meantime, the indicolite and teal tourmalines I’ve worked with are genuine joy — and they’ve made some of the most joyful pieces in my portfolio…
If any of this has caught your eye, come and find me — browse the portfolio, visit the studio, or drop me a message. I love talking about this stuff almost as much as I love making it.
