We've heard of plenty of celebrities getting in trouble for not returning borrowed jewelry but Rihanna has a better excuse than most, hers was taken in as evidence. A lawyer for Rihanna filed a motion in Los Angeles County Superior Court last week seeking the return of $1.4 million in jewelry the singer was wearing on the night of the Grammy pre-party on February 7. That was the night she was allegedly assaulted by Chris Brown and the pieces including earrings and several rings were seized as evidence in the case against him. Rihanna's lawyer says that the designers who lent the jewelry are concerned over getting their pieces back and that Rihanna had signed an agreement to return the pieces after the Grammy awards.

UPDATE: The police have agreed to return the jewelry.

Lauren Wolf has a terrific collection of gothic, ocean-inspired jewelry.

After studying jewelry design in coastal Mexico, Wolf moved to Brooklyn, NYC, where she currently lives and works. Her pieces tend to come in darkened silver and also in green gold, making for two price tiers - one in the low hundreds and one in the higher hundreds and low thousands.

Those who travel a lot know how easy it is to accidentally leave something behind. It must be exponentially more difficult for always-travelling Angelina Jolie to keep track of things. Small wonder then that the star left behind a pair of Asprey earrings. According to the Daily Mirror, Jolie wore the diamond earrings with her Armani Prive dress at the Bafta awards but left them in her suite at the Dorchester hotel before taking off. The Mirror reports that she realized that she had forgotten the earrings before leaving the country and called the hotel which found them and sent them on to Los Angeles. Better to leave the diamonds behind than one of the children.

Louis Vuitton has just launched two patented diamond cuts.

These tough economic times give us few excuses to splurge on items that will be out of fashion in a couple of months. Louis Vuitton diamonds are the antidote to this problem.

You probably recognized the maker of these diamonds before even reading the heading. That's the kind of brand recognition that guarantees the longevity of Louis Vuitton.

These classic cuts, reminiscent of Louis Vuitton's signature prints, are sure to be in style forever. Size may vary, but these are the kind of diamonds you pass down to your grandchildren. They are not so much a splurge as a sensible diamond investment.

The rounded and pointed flower cuts you see at right may not be right for an engagement ring (who would brand love like that?), but for earrings and other decorative jewelry, these cuts are sure to be a hit.

The Vuitton diamonds have between 61 and 77 facets and have been set into a bracelet, a pair of earrings, two brooches, a ring and a necklace-the latter consisting of 1,001 tiny brilliant-cut diamonds totaling 15 carats, coexisting with 65 round flower diamonds (49 carats) and 79 pointed ones (44 carats), for a combined bling bang of 108 carats that retails for about $4 million.

I'd most like a pair of studs just like these. Mismatched, but recognizably a pair.

Heavy, chunky, and bold, this bracelet from H. Stern's Feather Collection still manages to have an air of delicate femininity about it. The coordinating earrings are dainty and fluid, and I think the pair would make the perfect "little black dress" accessory set and would be sure to get admiring glances. Made of just over 123 grams of 24k brushed yellow gold (I would prefer it in silver myself), this little bit of arm candy can be yours for $21,000 (add the earrings for just $4,900 more).

Brazilian designer Manoel Bernardes creates beautiful pieces using the gemstones mined in his homeland. His pieces are bold styles that reflect the Brazilian spirit.

His Photon series has a spacey, futuristic look while the Romance series uses stones in a heart shape like the earrings above. Some of his most dramatic styles are the Lace pieces use gemstones combined with large loops of gold. These and other designs are in the gallery below.

Fashion designers have their haute couture lines and their ready-to-wear collections. High-end diamond jeweler, Daniel K, has a dazzling diamond and platinum couture jewelry collection but now there is Daniel K Prêt-à-Porter, the luxury jeweler's first entrée into the gold arena, the jeweler's version of ready to wear. Since 1999, Daniel Koren, the young jeweler behind Daniel K has been creating jewelry with diamonds and platinum and his pieces have been worn by celebrities including Debra Messing, Mary J Blige, Sigourney Weaver and Halle Berry.

The Daniel K Prêt-à-Porter line is a a recently unveiled, collection of modern earrings, bracelets, rings, and necklaces featuring pavé diamonds set in 18k rose, yellow or white gold. The collection offers a variety of pavé diamond encrusted, round and oval hoops in different widths and sizes. I also love the colorful stacking bangles which are available in different colors featuring rubies, sapphires, tsavorites and diamonds and can be worn together or individually. The bangles are hinged and have a release button for getting them on and off easily.

The most dramatic pieces are the ones that feature black and white diamonds. The bracelet above is part of a set that has black and white diamonds set into rhodium blackened white gold for a distinctive and slightly gothic look. The Prêt-à-Porter collection is more moderately priced than the Daniel K Couture collection, retail prices range from $2,500 - $60,000.

Jewelry designer Emily Amey takes her inspiration from nature's small wonders. A sprig of seaweed becomes a delicate necklace, the tendril of a vine coils to form a slim bangle, the tentacles of a squid are reimagined as dramatic hoop earrings under her keen eye. She designs in both gold and silver, using found beachglass in ethereal shades of blue-green as adornment. One of her biggest inspirations from the aquatic world is the lace-like seafan, whose image is shown in the three pieces above.

Jewelry designer Kimberly McDonald combines the worlds of fine jewelry and mineral collecting with Rockras, jewelry that combines geodes and agate with diamonds and sapphires. Each bespoke piece of Rockras jewelry is made by hand in the United States. The earrings shown here feature pink sapphires and rose cut diamonds.

Reversible and detachable elements highlight this designer's beautiful work but truly her entire line currently at Neiman Marcus is stunning. Whether you prefer the Day & Night earrings and necklace, the feminine flower ring or the necessary gold hoops with a splash of sapphire or tsavorite, Nam Cho's work will bring the beauty out in you. Personally, I love the idea of jewelry that translates well from the work day to an evening out with just the flip of pendent...more likely I won't miss Happy Hour by fumbling for that other pair of earrings in the depths of my handbag.

Fitting into the long, straight earring style with a bit of fiery flare, the matchstick earrings by Laura Lobdell are kind of fun! Sterling silver with copper tips, two-inches in length, they are hand cast from real matches and come in a cute little box that says, "I play with fire". For $175 they certainly bring subtlety and originality to your Valentine's gift. There's also a necklace for the same price if you want to go all out. Tell her she's 'hot' with this gift and she'll be happy you noticed.
