We acquired the stones a few years back from an Aussie opal cutter in Lightning Ridge, Australia, then sent them to Nepal last year.

It was interesting to see just how the platinum mounting and the Tanzanite were holding up– Our client Bill is a race-car driver by avocation, so we’re sure the piece got plenty of banging […]

She had inherited the stone, which was accompanied by an appraisal from a gemologist which described it as a “Canary Yellow” diamond, which implied but didn’t state specifically that the stone was natural-color. Our client said the diamond had originally been […]

These days, we buy a lot of jewelry, used as well as new. Today, I worked with a young lady, a bit down on her luck and on the rebound from a relationship that didn’t work out. She was looking to sell her white gold solitaire ring that was set with the one carat round […]
