Some diamonds are not loud — they just have presence.

This one-of-a-kind marquise yellow diamond ring is built around a 2.02ct natural fancy very light yellow diamond. The colour is soft and golden, not bright yellow in a theatrical way. That was exactly what made the stone interesting to us.

A marquise cut is never just about sparkle. It is about line, proportion and how the stone sits on the hand. The pointed ends need protection, the setting height matters, and the side diamonds have to frame the centre stone without fighting it.

Here, the mix of 18ct yellow and white gold helps the ring keep its balance: warmth around the yellow diamond, crispness around the white diamond accents.

It could be worn as an engagement ring, a dinner ring, or simply as a serious personal piece for someone who wants colour, but in a grown-up way.

This exact ring is one-of-a-kind, and a similar version can also be made as a bespoke commission around a different diamond size, yellow tone, metal or setting style.

Handcrafted in London. Natural diamonds. Independent certificate. London hallmarking.

A one-of-a-kind marquise yellow diamond ring in 18ct white and yellow gold. Available as shown, or commissioned as a bespoke cocktail, dinner or engagement ring with your chosen diamond, metal and details. Handcrafted in London.

Diamond tennis necklaces and graduated diamond necklaces are some of the most technically demanding pieces in fine jewellery 🎾💎

They look effortless when they are made well. That is exactly the challenge👌🏻

A diamond tennis necklace must sit smoothly against the skin, follow the collarbone naturally and allow every diamond to work as part of one continuous line of light. A graduated diamond necklace adds another layer of complexity, with each stone carefully selected so the transition in size feels seamless rather than obvious.

At Lena Cohen Jewellery, we create bespoke diamond necklaces in platinum, white gold, yellow gold or rose gold using natural diamonds. Every piece is made to order and individually planned around the diamond size, total carat weight, proportions and the way the necklace will be worn.

Some clients choose a refined diamond tennis necklace for everyday wear. Others commission a graduated diamond necklace with larger centre stones for a stronger statement and more dramatic presence on the neck.

Natural diamonds.
Certification.
Made to order.

One detail that photographs rarely capture is how a necklace moves. A beautiful diamond necklace should feel balanced, flexible and comfortable from every angle, whether it is worn with a simple shirt, an evening dress or absolutely nothing competing with the diamonds.

We specialise in bespoke diamond tennis necklaces, graduated diamond necklaces, natural diamond necklaces, and custom fine jewellery created around the individual client.

This is what fine jewellery in London actually looks like when pieces are being made, adjusted, polished, hallmarked, set, checked and sent back to the bench again.

At Lena Cohen Jewellery, our work happens between Hatton Garden, the London Assay Office and the bench, making solid gold jewellery, diamond rings, natural diamond studs, bespoke pieces and made-to-order fine jewellery in London.

Honestly, real jewellery workshops are not especially glamorous. They smell like polishing compound and metal dust. Benches get scratched. Tools get worn down. People drink coffee while discussing claw settings, stone proportions and millimetres most customers will never notice consciously but feel when wearing the piece.

How Much Should You Spend on a Diamond Engagement Ring? UK Guide 💎💍

There is no single “correct” amount to spend on a diamond engagement ring. The old salary rules are outdated, but that does not mean budget is irrelevant.

With a fine engagement ring, the question is not simply how much does it cost? It is what are you actually getting for that budget?

A diamond engagement ring in the UK may range from around £1,500 to £10,000+, depending on the diamond, metal, design and craftsmanship. But two rings at the same price can look and feel very different.

Carat affects presence💎
Cut affects brilliance💎
Clarity and colour affect refinement💎
Gold or platinum weight affects how the ring wears over time✨
Craftsmanship affects everything⚒️

Some clients want a larger natural diamond. Some prefer a more refined stone. Some want a timeless solitaire, a trilogy ring, or a bespoke design made around a specific hand, lifestyle and story.

At Lena Cohen, our engagement rings are made to order in London in 18k gold or platinum, using natural diamonds selected around your priorities.

A good engagement ring budget should feel considered, not pressured.

How much should you really spend on a diamond engagement ring?

There’s no fixed rule — and there never was. The old “two or three months’ salary” idea is outdated and doesn’t reflect how people actually choose rings today.

In reality, engagement ring budgets vary widely. In the UK, many sit anywhere from around £1,500 to £10,000+, depending on the diamond size, quality, and overall design.

What matters more is how that budget is used.

A larger diamond creates presence.
A better cut brings more light and brilliance.
A well-made setting and proper gold weight ensure the ring lasts beautifully over time.

Different choices lead to different results — and none of them are “wrong.”

At Lena Cohen, we create engagement rings to order in 18k gold or platinum, using natural diamonds selected around each client’s priorities. The process is less about hitting a number, and more about finding the right balance between size, quality, and design.

Because the real question isn’t “how much should you spend.”

It’s: what kind of ring will still feel right — not just now, but years from now.

Before You Buy “Gold” Jewellery, Check This

A gold label is not enough.

In the UK, 9ct gold is usually marked 375.
18ct gold is usually marked 750.

That means 9ct gold contains 37.5% pure gold, while 18ct gold contains 75% pure gold — twice as much.

If you are choosing fine jewellery, especially pieces with natural diamonds or gemstones, the metal should match the quality of the stones.

Our guide explains what 9ct vs 18ct really means: https://lenacohen.co.uk/karats-in-gold-navigation/

The best diamond studs are chosen by size, cut, setting, metal, backing and fit — not carat alone. For everyday wear, look for natural diamonds in 18k solid gold, a setting that sits close to the ear, a secure back, and a post or barbell length that suits your lobe or cartilage placement.

If you want one reliable first pair, choose a round brilliant diamond in a balanced everyday size. If your studs tend to tilt forward, especially on softer or older lobes, a martini or bezel setting with a more precise post length can make a visible difference.

Diamond Studs explained for real life: on-ear proportions, shapes that suit, screw vs flat backs, and fit for mature lobes and helix.
