The beautiful Kate Middleton officially announced her engagement to Prince William and wore an Issa London dress to her first press conference. The tight-fitting royal blue jersey and silk dress with a gathered front was appropriately named 'Sapphire.' It has been reported that her dress sold out in the UK within hours. The dress was priced at £385 or about $615. It is not available in the US.
Kate was given the ring that once belonged to Diana, Princess of Wales. When it was given to Diana in 1981, it cost £30,000. The ring is made from 14 diamonds encircling a sapphire.
Kate's earrings and nacklace Tiffany & Co. 18k Gold
by designer Elsa Peretti.
The necklace is 16" long and is set with a center cabochon
blue sapphire and two diamonds. The diamonds are about 5 points
each and the sapphire (including the gold setting) measures 5/16" x 3/16"
The necklace is signed Tiffany & Co., 750 (i.e. 18k), Peretti"
Tiffany & Co reissued a similar necklace. The main difference is that the center stone is round and not oval like Kate's above. Also, the center stones could possibly be different (lapis lazuli cabochon vs. a blue sapphire). I will contact Tiffany & Co for clarification.
The Tiffany & Co website describes the 'Elsa Peretti® Color by the Yard' necklace as:
"Necklace in 18k gold with one lapis lazuli cabochon and two round brilliant diamonds. 18" long. Carat total weight .10. Original designs copyrighted by Elsa Peretti ($995)"
Tiffany & Co
There is much debate about whether Kate's necklace and earrings are sapphire or lapis lazuli. There is no way for us to be sure unless the palace confirms or denies either way. Tiffany & Co does currently have similar earrings - the oval Elsa Peretti Color by the Yard earrings in 18k gold with lapis lazuli center stones ($750).
