Nicky Hilton, the younger sister of Paris Hilton, is finally showing off her beautiful engagement ring.

Previously, Nicky had only given her fans a glimpse of her diamond as she went about her business in New York.

However, she recently decided to post a close-up of the ring to her personal Instagram account.

The 30-year-old fashion designer posted the photo on Friday, September 19, as a flash back Friday post, in which people post an older “flashback” picture.

“#engagementmoon in Paris #FlashbackFriday,” she captioned the photo that showed her flashing her ring while touching her hair near the Eifel Tower.

According to People, the ring seems to be a “princess-cut center stone with two diamonds flanking the sides on a gold band.”

“Nicky’s ring looks to be a five-carat Asscher cut diamond in the center with two trapezoid diamonds on either side,” said David Allen of 77 Diamonds. “The nature of an Asscher cut means you really need to get the highest quality in order to feel the true beauty of the stone so a ring of this caliber and size would be worth around £250,000.”

Nicky got engaged to British banker James Rothschild in early August. The proposal took place Italy’s Lake Como during the couple’s trip through Europe for their anniversary. Rothschild popped the question, on bended knee, while they were sailing on a romantic boat ride.

“They are both really excited and incredibly happy,” a source revealed to US Weekly. “He took her out on a boat into the middle of Lake Como and he proposed, got down on one knee and everything. It was incredibly romantic and beautiful.”

Paris immediately took the time to congratulate her little sister by posting a congratulatory message on her Instagram account.

“Congratulations @NickyHilton on your engagement! I’m so happy for you! You will be the most beautiful bride! Such a lovely couple! Love you both so much!,” she wrote alongside a picture of the pair holding hands.
