I am not sure that your pic is of the best diamonds at all. They were shortened rather soon to make the bracelet, seen in my second pic here.
Edit: you might have found the long version Bryce, after all. I have a pic of the necklace worn full length and am now trying to find it.
The original best diamonds (once) and the shortened (twice).
