Princess Diana's twin nieces Lady Amelia and Eliza Spencer put on glittering displays in contrasting dresses for jewellery launch at the National Gallery

The Spencer sisters looked stunning as they dressed to the nines for a jewellery launch in London on Wednesday evening. 

Lady Amelia and Lady Eliza, nieces of the late Princess Diana, put on a typically glittering display as they attended the luxury event at the National Gallery.  

The socialite twins, 31, posed on the gallery's famous steps as they oozed luxury while modelling items from the new collection from jewellery brand Boodles. 

Lady Amelia opted for a black Alexander Wang dress with a statement semi-sheer neckline, skirt and sleeves for a chic look. 

Her stunning gown was embellished with black jewels, while she added Dior make-up for a glowing look.

Meanwhile Eliza's contrasting look in green meant both twins stood out from the crowd. 

The blonde beauty turned heads in her eye-catching dress, which caught the eye with its silver jewels, semi-sheer sleeves and wisp effect on the fabric. 

The elaborate dress highlighted the simple but effective impact of the jewellery, with a gold bead necklace and the Knot Yellow Gold Diamond earrings, ring and bangle.  

The twins made sure to flash the collection's impressive rings, while Amelia slicked her hair back into a fashionable ballerina-style bun to allow her £15,000 Rubellite Diamond drop earrings to take centre stage. 

The event was celebrated a pre-launch for Boodles for 2024 - and it is a brand often worn by the twins.  

At high profile events, they often opt for a contrasting look to one another for an impactful display. 

The stylish siblings, the daughters of Earl Spencer, Diana's brother, are a regular at fashion house events.  

At the Air Ambulance Ball in February, which was also attended by Prince William, they looked elegant at the glittering black and white gala dinner at Raffles London at the OWO (Old War Office).

Amelia went for a bright colour palette as she donned a white slim-fitting dress with bow detailing across the chest, embellished with a mesh top and jewels around the bodice. 

Meanwhile Eliza made sure to complement her sister's look with a glittering black number, complete with semi-sheer sleeves and jewelled belt, perfectly off-setting Amelia's look. 

Amelia and Eliza grew up in South Africa but moved to the UK three years ago, and have been enjoying the couture scene ever since. 

Speaking to The Telegraph in 2021, the duo discussed their childhood in the wealthy suburb of Constantia in South Africa, admitting they don't use their titles outside of the UK and had a 'normal, happy childhood.'

When asked about what they like to do with their father Charles, the twins referred to childhood memories.

They explained: 'Football, competitive croquet, hide-and-seek. Growing up, the house would always be busy, full of extended family and friends.’

Explaining why they decided to move to London in 2021, Amelia added: 'Cape Town was all about the sea, hiking, horse riding, tennis, netball... After high school and university we were so happy that we didn’t feel the need to move, but the last few years we found our confidence.

'In London everyone seems so driven; it makes you want to reach your full potential.’
