Kim Kardashian and Her Family Wore "Millions of Dollars'" Worth of Jewelry ...

It's usually a smart idea to go with what you know, for a fact, works.

So that's probably why Kim Kardashian and her family were decked out in 'millions of dollars' worth' of jewelry this weekend by Lorraine Schwartz, a friend of the family and the bling expert who provided Kim's eye-popping 15-carat engagement and the diamond-encircled wedding bands she and husband slipped on each other's fingers on Saturday.

The bride, sister Khloé Kardashian, mom Kris Jenner and more wore different pieces by Schwartz for all of the Kimye wedding festivities, sources tell E! News.

Schwartz, who attended the wedding, posted a rather dazzling photo on Instagram of a number of necklaces, bracelets, rings and earrings-including what appear to be the mother of the bride's diamond studs and the ruby rings that Khloé wore to the brunch that Valentino threw for the family at his château in France on Friday.

'The jewelry is a mix of new and vintage cuts, reminiscent of old-world opulence,' celebrity jeweler and diamond expert Jean Dousett tells E! News, describing the various baubles Schwartz displayed.

'The theme is definitely retro with a touch of modern geometric pieces,' he said, noting the funky V-shape ring and pavé pyramid bracelets.

'Most of the jewelry has a darker patina of metal over bright white, if you will,' Dousett continued. 'The big necklace has old mine-cushion cuts with clusters of stones around, circa turn of [the 20th] century.'

And though we're told that Kim chose to wear her own deceptively simple-looking diamond studs because, for the same reason she wanted a refined wedding band, she didn't want to take away from her engagement ring, her round-cut diamonds look to be just under three carats and could retail for close to $200,000, according to Dousett.

Not too shabby.

'There are two line diamond necklaces,' Dousett added. 'One of them is called a Sautoir [a long necklace from which suspends a tassel or other ornament], which was probably worn with the other as a double layer. I have not seen the images of the wedding, but I am guessing.'

And yes, Dousett estimates that there could be a couple of million dollars' worth of jewelry in Schwartz's picture alone.
