LJ West Takes Its Pinks Back to Australia
The New York-based company took the fancy colored diamonds it bought from the Argyle mine to jewelry stores Down Under.

New York--L.J. West took some of its pink and purple diamonds back to where they came from.
The New York-headquartered diamond company is on a tour of Australia this month, taking the Scott West jewelry collection to Perth, Sydney and the country’s Gold Coast.
The first stop on the collection’s tour was the Crown Metropol showroom of retailer Linneys from Oct. 13 to 15.
It then went on to private viewings in Sydney before heading to Calleija Marina Mirage, a jewelry store on Australia’s Gold Coast.
There are more than 60 pieces of jewelry in the collection, including the amazing Argyle Violet, a 2.83-carat fancy deep grayish-bluish violet diamond, which is the biggest violet diamond ever recovered from the Argyle mine in Western Australia.
L.J. West bought the diamond at the 2016 Argyle tender. The company, which specializes in fancy colors, set it in a ring with a halo of vivid pink diamonds.
For a time, the stone was on display as part of an exhibition of outstanding diamonds at the Natural History Museum of Los Angeles.
The collection also includes the 2.24-carat Argyle Thea, a fancy vivid purplish-pink that L.J. West also purchased at the 2016 tender.
Now, the Argyle Violet and the Argyle Thea are back where they came from as part of what L.J. West says is the largest collection of fancy colored diamonds and diamond jewelry ever on display in the Southern Hemisphere.
Linneys puts the value of the collection at more than $100 million.
