Under the Loupe: The Oscars - Red Carpet Jewels 2014

Another awards ceremony has been and gone ... and this one was certainly sparkly in the jewellery department - although a bit lacking for colour with diamonds the overwhelming choice.

If you are an A list star with a shortlist of gowns that you may not chose til the day, perhaps they chose diamonds so they don't have to match colours of gems to the dress?

There were a few more necklaces evident on the big names - Naomi Watts (at top) has regularly worn necklaces to awards ceremonies over the last few years and did so again this time wearing a geometric diamond collar by Bulgari.

Jessica Biel chose an aquamarine and diamond ensemble from Tiffany & Co. from their Blue Book collection.

Jennifer Lawrence repeated her back necklace idea again this year with Neil Lane diamonds, although it looked fine from the front, I think the look was more successful at the back of the gown last year with a longer necklace.

Charlize Theron went for a pendant look with a 31 carats diamond studded drop by Harry Winston. It look fabulous with her sleek black gown.

Kristen Bell wore a Piaget diamond collar along with her pale dress and could have been quite ice-maiden without the soft hair updo.

Idina Menzel is quoted as requesting Italian jewellery company Chimento to design a collar for her classically styled dress

I did note one necklace with some colour - a labradorite necklace and earring set by Shamila, worn by Suzanne Marques which enhanced her grey dress beautifully.

Earrings abounded of course, as they always do, and diamonds were once again the favourite.

A highlight in colour were the Tiffany & Co. earrings worn by Amy Adams, featuring pink rhodochrosite and blue lapis lazuli and turquoise.

Cate Blanchett did have a little colour in her white opal and diamond earrings by Chopard but that colour was hardly visible, but I applaud her choice of 'not diamonds'!

Anna Kendrick wore some black gem and diamond drops by Piaget. Just a little different and a lovely choice.

Calista Flockhart added a pop of colour to her otherwise white ensemble with emerald and diamond earrings by Jacob & Co.

Jenna Dewan-Tatum wore Lorraine Schwartz diamonds as did Sandra Bullock.

Julia Roberts went for diamonds by Bulgari...

...and Penelope Cruz chose diamonds by Chopard...

...while Angelina Jolie reportedly spent quite a bit of time finding just the right pair of diamonds to go with her dress. The diamonds total a hefty 42 carats and were made into earrings by her jeweller.
