Celebrities believing in the healing properties of crystals is not new, so it's not a total surprise that Robin Thicke founded himself at Crystalarium on Wednesday.

The singer was seen exiting the store, which is full of crystals, carrying a two-foot amethyst stone that cost $20,000, notes the Daily Mail. Thicke has seen some troubled times lately, as he and wife Paula Patton have separated. Thicke smiled as he carried the bulky package. He was dressed down in a blue T-shirt, jeans and sneakers. He also carried a Crystalarium tote bag that appeared to have a booklet inside of it.

Thicke has been open about wanting to make things right with his wife.

After a series of incriminating images showed that Thicke may not have been faithful to Patton, the two separated.

Thicke took his 3-year-old son, Julian, with him to buy the crystal.

An amethyst is considered the stone of St. Valentine. It represents faithful love and is tied to "the energy of fire and passion."

At the Billboard Music Awards, Robin Thicke dedicated "Get Her Back" to his high school sweetheart.

Crystalarium was founded in 1987. It is located on Melrose Avenue in Hollywood, and plenty of celebrities have been seen shopping there. For example, Leona Lewis walked away with a big crystal last year. And in November, Jaden Smith and Kylie Jenner were spotted there together. The maybe-couple then shared pictures of their purchases on social media.

Thicke is being persistent, as it is also reported that he will name his new album "Paula," according to Us Magazine. The album will drop on July 1, and it will include the song he dedicated to her.

Do you think Thicke and Patton will be getting back together?
