Custom Engagement Rings

How LMK
came to be...

We’re celebrating your unique love story.

We believe your engagement ring is more than just jewellery; it should symbolise the journey you and your partner have shared.
 

Your love story is one-of-a-kind, filled with moments that deserve to be honored uniquely.
 

LMK custom engagement rings begin with you - your memories, you and your partner’s style, and the essence of what makes your relationship so special.
 

We’re here to help transform those cherished memories into a timeless heirloom, as meaningful and durable as it is beautiful.​

Sketched on the back of an envelope.

Inspired by her own last-minute Mayan wedding ceremony in Mexico just 3 months after our founder Lydia (pictured) and her partner met, she sketched the very first LMK engagement ring on the back of an envelope.

 

She wanted to create an heirloom to remind them of that day - something beautiful to serve as as a time-machine of their youth. 

​

A professional background in corporate mining helped with making those first connections within the diamond industry, and LMK was born. Today, Lydia creates her unique designs in London before they are handcrafted by specialist artisans using ethically sourced, premium materials.

 

Commissioning a bespoke engagement ring inspired by your shared journey together is a wonderful opportunity to celebrate your love, where every detail is personalised to you.​​

Custom made engagement rings which connect you.

She envisioned something tough yet timeless, feminine, and deeply meaningful - a true heirloom crafted from heritage materials.

 

That first sketch has become a brand which places couple's at the heart of every design.

 

Even today, Lydia starts by sketching every design by hand before her team of skilled artisans bring each design to life in accordance with the couple's style and practical needs.

The power of 'The One'.

We believe there is only one engagement ring - the one that tells your unique love story.

​

From the moment you propose to the day your ring is passed down through generations, it should be more than a symbol.

 

It should reflect the bond that connects you, serving as a reminder of your journey and an invitation to grow together. Through every moment, it will inspire you to cherish the love and joy that lies ahead.
