They say that diamonds are a girl's best friend, and actress Lily James, who is seemingly never without her trusty jewels, is the living proof.
The 33-year-old is a global ambassador for Only Natural Diamonds, a platform set up by the Natural Diamond Council in effort to "advance the integrity of the modern diamond jewellery industry" and "inspire, educate and protect the consumer".
The theme of the video campaign, which was originally released in September of last year, centres around an actress, played by Lily, who has harnessed the versatility of the precious stone, wearing diamonds on set in a 60s themed ensemble, to a glamorous awards ceremony, as well as on the street with a super low-key outfit.
The gamine look is worlds away from her hit Disney+ series, Pam & Tommy where Lily played industry icon Pamela Anderson. Lily was nominated for an Emmy for her critically acclaimed performance.

The Downton Abbey star admitted she sent Pamela a letter stating she wanted to "honour" her in her portrayal.
The Baywatch star has since created her own Netflix documentary Pamela, A Love story in order to "take back control of the narrative" and the e-mail from Lily was allegedly left on read. Pamela has said of Lily's involvement in the series, "It's not her fault; it's a job," telling The Guardian, "But whoever created it – well, it just feels like something else stolen."
In a recent post shared on Only Natural Diamonds' Instagram page, Lily schooled her fans in how to incorporate diamonds into a casual ensemble. She wore a simple round neck top under a relaxed-fit beige blazer with matching straight-leg trousers, topped off with a navy cap and classic white trainers.

The actress finished off her minimalist style moment with the Embrace Link Choker, and a classic Tennis bracelet, juxtaposed against the celestial inspired Made by Malyia Soleil bracelet. As for her earrings, Lily turned to Anita Ko's Diamond Loop style which felt suitably cool and understated.
The inimitable beauty of a diamond is hard to resist. However, with the stones being rooted beneath the earth's core, we now know much more about how dangerous the diamond mining process can be, and the harmful impact that it can have on its workers and their communities.
Only Natural Diamonds is committed to responsible and ethical business practices, which Lily experienced first-hand at the end of last year.
The Pam & Tommy star travelled to Botswana, describing herself as "awestruck by the natural beauty" in the caption of an Instagram post shared with her 3.3m followers.
"To know so much of this land—over 1,000 square miles globally is protected by the natural diamond industry makes me incredibly proud to be @onlynaturaldiamonds global ambassador," Lily wrote.

We’re still reeling from Lily's stylish appearance last month on the Golden Globes red carpet. The actress exuded leading lady glamour in a voluminous red Versace gown and rocked her 90s bombshell flicky bob with flair, but the sartorial detail that caught our eye the most was her delicate floral diamond necklace by Harry Winston.
