Trilogy Diamond Engagement Ring, Made Around You 💎

A trilogy engagement ring has been part of British jewellery making for generations. Three diamonds. A balanced design. A ring that feels timeless whether it is made today or handed down decades from now.

At Lena Cohen Jewellery, every trilogy ring is made to order in our London workshop.

Some clients prefer a classic round brilliant centre stone with pear-cut side diamonds. Others choose larger side stones, different diamond grades, platinum instead of gold, or a completely bespoke interpretation of the trilogy design.

Because you deal directly with the jewellers, there are no sales consultants, showroom commissions or layers of middlemen between you and the workshop. If you have questions about diamond size, colour, clarity, finger size, setting style or budget, you speak to the people who are actually making the ring.

Every ring is crafted in solid 18ct gold or platinum and hallmarked in the United Kingdom. Natural diamonds are used throughout, stones are supplied with independent certification from recognised laboratories such as GIA.

We are a family-run British jewellery business built on traditional workshop values. The approach is straightforward: honest advice, careful craftsmanship and enough time to make the ring properly.

Whether you are looking for a delicate trilogy ring, a vintage-inspired design, a larger diamond centre stone, platinum construction or a fully bespoke engagement ring, we can create a ring tailored specifically to you.

A bespoke diamond cross necklace, made to order in London.

This piece was created for a client who wanted a large diamond cross with presence, natural diamonds and a chain that could be worn at different lengths.

The necklace has adjustable length points, so it can sit higher or lower depending on the neckline. The clasp was also made as part of the design: a diamond-set lobster fastening instead of a plain closure.

These details are part of the bespoke process. Stone size, diamond quality, chain length, clasp, setting style and proportions are all discussed before the piece is made.

At Lena Cohen Jewellery, bespoke diamond jewellery is made to order in London, with direct contact throughout the process, carefully selected stones and certificates where applicable.

Bespoke projects start from £3,000, with the final price depending on the design, diamonds, metal and level of detail.

Diamond tennis necklaces are often described as simple jewellery💎

From a manufacturing perspective, they are some of the most technically demanding pieces we create.

A well-made diamond necklace needs to balance flexibility, security, comfort and visual consistency across every stone. The challenge becomes even greater with graduated diamond necklaces, where diamond size changes gradually towards the centre while maintaining a natural flow around the neck.

At Lena Cohen Jewellery, we specialise in bespoke diamond jewellery made in the UK, including diamond tennis necklaces, graduated diamond necklaces, engagement rings, wedding rings and custom fine jewellery.

Every piece is made to order using natural diamonds selected individually for each project. Certification is provided where appropriate, and clients work directly with us throughout the process rather than through retail intermediaries.

Many people searching for a diamond necklace focus on carat weight first. In practice, proportions, diamond spread, necklace length, flexibility and construction often have a greater impact on how the finished piece looks and feels when worn.

One thing I have learned from making diamond necklaces:

People rarely ask about the part that matters most.

The first questions are usually:

How many carats?
What colour gold?
What certification?

All sensible questions.

But when a client finally puts a diamond necklace on, something else decides whether they love it.

How it sits.

A diamond tennis necklace should follow the collarbone naturally. It should move comfortably when you walk, turn your head or reach for a glass. A beautiful necklace can feel surprisingly wrong if the proportions, articulation or balance are not carefully planned.

This is one reason bespoke jewellery still matters.

A necklace is not simply a collection of diamonds. It is a piece that has to work with a specific person, a specific neck, a specific style and a specific way of wearing jewellery.

At Lena Cohen Jewellery, every diamond necklace is made to order in the UK using natural diamonds selected individually for each project. We provide certification where appropriate and work directly with clients throughout the process.

The diamonds are important.

The engineering behind them often decides whether the necklace becomes a favourite piece or spends most of its life in a jewellery box.

How do you style a diamond tennis necklace?

Keep the neckline clean. A shirt, silk blouse, cashmere knit, black dress or strong colour like cobalt blue gives the diamonds space to catch the light.

Can you wear a diamond necklace during the day?

Yes. A diamond tennis necklace looks modern when it is styled simply: pulled-back hair, natural skin, one strong neckline and very little competing jewellery.

What is the difference between a tennis necklace and a graduated diamond necklace?

A tennis necklace usually has diamonds of a similar size in one continuous line. A graduated diamond necklace has stones that become larger toward the centre, creating more focus at the front of the neck.

How should a diamond necklace sit on the neck?

It should follow the collarbone smoothly, without twisting, lifting or feeling stiff. Movement matters. A well-made diamond necklace should sit comfortably when you turn your head, walk or move your shoulders.

What makes a diamond necklace look elegant?

Proportion. The diamond size, necklace length, neckline, earrings and outfit all affect the final look. The best diamond necklace styling usually looks clean, balanced and easy.

Single Round Diamond Ring in 18ct Yellow Gold💎✨👌🏻

An everyday diamond ring crafted in solid gold and designed to be worn for years, not seasons.

A small natural round diamond, a smooth bezel setting and a slim durable 18ct yellow gold band. The kind of ring that becomes part of your daily jewellery without ever feeling overdone.

Some pieces spend most of their life in a jewellery box. Others end up being worn with everything.

This is one of those rings.

Easy with a white shirt. Easy with knitwear. Easy stacked with other rings or worn completely on its own.

The round diamond catches the light beautifully, while the bezel setting keeps the look clean, modern and effortless.

Wear it alone for a subtle diamond detail, or add another fine ring later if you enjoy building a stack over time.

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.

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.
