Ashlee Simpson's engagement ring exclusive photos from designer Neil Lane

People says when it came to designing a one of a kind engagement ring for Ashlee Simpson, actor Evan Ross got creative and unique. "He took it very seriously and it was a wonderfully intense process," says L.A. jeweler Neil Lane. Lane and Ross, 25, worked together pulling it tight to meet the deadline for the proposal. 

"Evan was really, really sweet and he was looking for something beautiful, a unique ring that said everything: love, romance, beauty, character. He didn't want anything traditional," Lane said.

After picking and choosing design options, a vintage marquise-cut diamond covered by small rubies caught the son of Diana Ross eye. "When he saw it, his eyes widened and that was it," the jewelry designer said. "But that was only the beginning."

Ross wanted to add a touch of contemporary feel, so the two made sketches and traded ideas. Ross even included Simpson's mother Tina, in the mix. The site also mentions that older sister Jessica Simpson also has a Neil Lane engagement ring.

"He wanted to do the right thing. This is a young fellow in love," says Lane, who also created a diamond sleeve for the original ring fit. "His taste level is exquisite and he wanted to make sure it was a perfect ring for his love."

The redesigned five-carat ring, set in platinum and gold, now has added 140 white diamonds with a touch of small rubies. "Evan was blown away when he saw it!" says the designer, who admits he was nervous about making the deadline before Ross and Simpson, 29, headed off to Hawaii last weekend. "It was non-stop until the last minute when Evan picked up the ring last Friday, but it was worth it. It's one of the most beautiful rings I've ever done." 

So what did Simpson think?  Lane, who spoke with Ross after he proposed said, "She was overwhelmed! Oh my God, they are so in love."
