Pippa Middleton flashes her '£200,000' engagement ring walking her dog Rafa - as it's revealed she will get her own title as Lady Glen Affric when she marries James Matthews 

Like any newly engaged lady, Pippa Middleton just can't stop flashing her dazzling diamond rock - even when going for a jog or taking the dog for a walk.

The Duchess of Cambridge's sister stepped out again on Thursday with her asscher radiant diamond ring, which is estimated to have cost £200,000, on full display.

Dressed in a summery mint green dress, which showcased her gym honed figure in all its glory, Pippa beamed as she left her Chelsea home, along with her cocker spaniel Rafa.

The family are keen on cocker spaniels - Pippa's brother, James, gave a cocker spaniel named Lupo to Kate and William as their wedding present

The same day, James Matthews - who popped the question over the weekend - was snapped with the cocker spaniel who is called Rafa (apparently named after Nadal)

Pippa's appearance - her third this week - comes as it's revealed that the author and party planner is set to inherit her own title. 

Whilst her big sister Kate owns the title of Duchess of Cambridge, Pippa will one day become Lady Glen Affric, according to The Express. 

Pippa's future father-in-law, David Matthews, is the Laird of Glen Affric and owns a 10,000-acre Scottish estate near Loch Ness in the Scottish highlands.

When David dies, James will inherit the title and Pippa will have her own title bestowed upon her as his wife, which she can use in the Commonwealth.

As Australian art historian Michael Reed explained: 'In coming years and particularly as the future Lady Glenaffric, Pippa Middleton will be able to entertain lavishly on her husband's grand Scottish Glen Affric Estate . 

'This is because Pippa herself comes from a family who is familiar with vast landed estates - her great grandmother Olive Middleton grew up at her family's Potternewton Hall Estate, near Leeds - leaving trust funds behind for her descendants.' 

You’ve certainly got this Matthews family who own this huge baronial castle.' He believes David inherited the plush title when he purchased the estate back in 2008.

Experts say that her centre diamond appears to be a 4 carat asscher cut diamond and given the nature of these step cut stones, the quality is paramount so the stone requires the highest of clarity gradings

Experts say a flawless asscher diamond set in an octagonal halo ring such as this would fetch upwards of £200,000 so it's little surprise that she can't stop wearing it

The Queen’s grandmother, Mary, has actually enjoyed a stay at the estate in the late 19th century. 

The Duchess of Cambridge's little sister has certainly been glued to her new diamond sparkler since her beau, hedge fund millionaire James Matthews, popped the question on the weekend.

A smiling Pippa accessorised her bling with a trendy snapback cap, white tank top, red sports shorts and trainers on Wednesday as she went for a jog wearing the dazzler.

After her brief jog, she arrived at her fiance's home in Chelsea. There, she picked up a gift of beautiful white orchids from Clapham Junction florist Neeva Jay and took them inside with her.

Pippa is already installed in James's magnificent, stucco-fronted house, where her betrothed has recently installed his and hers dressing rooms. 

Pippa clearly decided to make the most of the warm weather by going on a jog outside her home in Chelsea, south west London. 

She left home earlier on Wednesday morning, again flashing her engagement ring.

Dressed in a chic and feminine floral dress, which showcased her toned and tanned legs, the newly-engaged Pippa beamed with joy.

Her big sister, the Duchess of Cambridge, and Prince William are said to be 'absolutely delighted' with the announcement and have given the newly engaged couple their blessing.

A spokesman for the Cambridges said: 'The Duke and Duchess of Cambridge are absolutely delighted with the news.'

Pippa's father, Mr Middleton, added in a statement given to the Press Association: 'Carole and I are absolutely thrilled with the news. They make a wonderful couple and we wish them every happiness together.' 

It has, however, been suggested that Kate may not be able to serve as Pippa's maid of honour, with Royals author Judy Wade saying Kate would 'upstage her sister'.

She told People: 'It's a tricky situation for Pippa. She would want her sister by her side, as who else would she trust to make things go well? But if your sister is a future Queen, she is going to upstage the bride and draw attention. Kate would want to be in the background as much as possible.'  

Nevertheless, Pippa has continued to garner plenty of attention this week thanks to her ring.

Commenting on the dazzler, David Allen, Creative Director of 77 Diamonds, said: 'Pippa is not one to be outdone by her sister, we know that after 'that' dress she wore at the Royal Wedding in 2011. 

'Her centre diamond appears to be a 4 carat asscher cut diamond. 

'Given the nature of these step cut stones, the quality is paramount so the stone requires the highest of clarity gradings. A flawless asscher diamond set in an octagonal halo ring such as this would fetch upwards of £200,000.'

Sonia Menezes, Head of Brand Development at Clogau Gold, also believes the ring was pricey. 

'It has a vintage glamour with a modern edge, a style favoured by Gwyneth Paltrow and Jessica Alba, who have engagement rings of a similar style. The most famous Asscher cut diamond was worn by Elizabeth Taylor, the 33 carat Krupp diamond, now known as the Elizabeth Taylor diamond. 

'It was bought by Richard Burton for $300,000 in 1968. I imagine Pippa's engagement ring to be valued in excess of that.'

Newly engaged Pippa Middleton was seen leaving her home in London on Tuesday wearing her dazzling new diamond engagement ring from 40-year-old hedge fund manager James Matthews for the first time

A spokesman for the Cambridges, pictured at Wimbledon last week, said: 'The Duke and Duchess of Cambridge are absolutely delighted with the news'

Neil Geddes, a high-end jewellery concierge, said: 'It has a loose look of an art deco inspired piece, but it's likely contemporary made. It was likely to have been made bespoke especially for her from Bond Street.

'It sits fairly high on her finger allowing as much light to enter the diamond as possible and reflect back giving stunning brilliance and fire.'  

Rod Harris, a diamond specialist who owns WHY Jewellers in Dorset, added that the ring is 'very sophisticated and practical' with a design echoing themes of the deco era. 

An expert at the London Victorian Ring Company explains that Pippa's engagement ring has a central Asscher cut diamond which makes it 'really stand out.' 

Developed in Amsterdam in 1902, the Asscher shape has rows of facets similar to a staircase and each step is sparkling with the beauty of the diamond. The precise lines and distinctive cut corners made this a popular cut for 1920s engagement rings. 

Her Asscher cut diamond is surrounded by round brilliant cut diamonds and set in the shape of a octagon.

Harry Brown, CEO at Chisholm Hunter, said: 'James has made a very sophisticated choice in terms of the ring. It appears to be platinum and diamonds, possibly a ascher or cushion cut with a stunning round brilliant halo. 

'This is a classic style which is as timeless as it is elegant, and is a simply stunning ring which Pippa will enjoy wearing every day. Over the years we have seen variations on this style with pink and yellow diamonds but this is a real classic. It could be that James has designed the ring himself, making it even more personal – bespoke jewellery design is something that our clients are asking for more and more, as they want to give their fiancée something completely unique and special. 

'Pippa must be delighted with the choice. Congratulations to the happy couple.'

James asked Pippa to marry him last weekend during a weekend away in the Lake District and within a moment she said 'yes' and suddenly Britain's most eligible young woman was off the market.

Less than a year after she began properly dating the handsome hedge fund manager (they were briefly an item in 2012) the Duchess of Cambridge's sister is now engaged to be married.

Pippa and her fiance have shared their delight at their engagement and revealed they plan to marry next year.

The Duchess of Cambridge's younger sister and her future husband will wed in 2017 - in what is set to be one of the most talked about society weddings since William and Kate tied the knot five years ago.

'Miss Pippa Middleton and Mr James Matthews are delighted to announce they became engaged on Sunday 17th July and plan to marry next year,' they said in a statement released to the Press Association.  

Royal watchers are expecting Prince George and Princess Charlotte to play an important role - as page boy and flower girl, while Kate looks set to be her sister's matron of honour. 

It was the Royal Wedding in 2011, of course, that propelled Pippa to global fame after her star turn as her sister's chief bridesmaid and - thanks to a figure-hugging dress - the nickname of 'her royal hotness'. 

Matthews, 40, asked Pippa's father for permission for his daughter's hand before popping the question. 'James is a traditionalist and very much wanted to do things properly. That meant getting his future father in law's consent,' a friend of the couple told the Daily Mail's Richard Kay.
