We've dished the hairstyles, the makeup and (of course) the gorgeous gowns from last night's Golden Globes, but we haven't even scratched the surface when it comes to the stunning jewels adding the finishing touch to their red carpet looks. I worked directly with the Diamond Information Center to get the inside scoop on the hottest diamond styles and most expensive looks from the 2011 Golden Globes. Ready for a major case of jewelry envy? Here we go!

Helen Mirren, the queen of all that is classy and elegant, was absolutely dripping in $1.7 million worth of Cartier diamonds. The necklace alone has a total weight of 55.08 carats!

In addition to creating Mila Kunis' modern french twist, TRESemme's celebrity hairstylist Mara Roszak also tended to the tresses of newly blonde (thank goodness it's only for a role) Emma Stone. Taking a cue from Emma's simple and structured Calvin Klein gown, Mara crafted a style that is classically chic: the bun. To recreate her look at home, try Mara's easy steps:

• Step 1: Apply TRESemmé Fresh Start No Frizz Créme to damp hair
• Step 2: Blow dry using a round brush to sweep hair away from face
• Step 3: To give volume and height, tease crown and spray TRESemmé 24 Hour Root Boost Spray at the root
• Step 4: Smooth hair while keeping height at the crown and secure into a mid-height ponytail
• Step 5: Divide ponytail in half and twist the two halves around each other
• Step 6: Hold the ends firmly and wrap the twisted hair into a bun, pinning as you go
• Step 7: To set the style, finish with TRESemmé TRES Two Extra Hold Hairspray

How do you feel about Emma's look? Is this something you'll try at home?
