LONDON (Reuters Life!) - Warrior princesses, sultry ladies of the early 20th century, and innovative blends of ethnic cultures, are driving jewelry style trends into 2010.

Jaana Jatry believes that the "Warrior Princess" look, as shown above by Xena: Warrior Princess, will be driving jewelry styles in 2010

Jaana Jatyri, founder and CEO of Trendstop.com, said at the International Jewelry London (IJL) trade show that Boadicea, fabled warrior queen of the Britons, was a symbol of a new style trend emerging in jewelry for the summer of next year.

"The "Warrior Princess" theme is responding to the strong images of a more masculine trend in women's fashion," Jatyri told a seminar at IJL this week.

She highlighted the use of wood with metal, and multiple chain arrangements reflecting the warrior princess style.

Another key theme in jewel design, "Modern Boudoir" -- a timeless look with "French chic" -- was inspired by stylish women of the Art Deco period, such as Coco Chanel, the subject of two recent movies, and the movie star Marlene Dietrich.

Jatyri outlined other trends including "Nature's Alchemy -- different ways of blending nature and technology; "Organic Anatomy," the influence of organic structures such as snake skins and bones; and "The Witching Hour" -- a dark and mysterious style, reflected in the use of dark crystals, fish hook earrings, and resin-encased insect designs.

Jatyri also referred to a merging of cultures in jewelry design trends.

"There will be more trends that are about mixing cultures, mixing French chic with Indian style or Asian styles," she told Reuters television in an interview.

"That way we can create something new, like fresh looks that combine different elements from different cultures."

She said, "By combining different cultures, for example you might have a metal chain with a wooden pendant from India, or even something like Buddhist beads, prayer beads or something like that. And you use them as a necklace.

"So it's taking elements from different cultures and creating something new and a bit more fashion-based."

IJL runs until September 9 at Earls Court exhibition center in London.
