The Discussion

Tucson shopping list – do you go there with specific stones in mind or just see what you can find?

You must go with an open mind because you might find something. I go through my safe a month before, to study what I already have, and make spreadsheets of what I need. My greatest joy is that I get to shop for myself, but I also get to shop for my clients and get what they want.

What is your favorite find from Tucson?

To this day is the most spectacular black opal that has ever been mine, is a 306-carat black opal the size of your palm. I also found these insane canary tourmalines; they are neon yellow and I am putting them in my new collection this summer.

White topaz is one of my favorite signatures I work with, I have been working with them for over 12 years now.

I find the best things I can possibly find in Tucson, then you run to me at couture first and scoop up all my best pieces for the store.

On Opals:

I have been visiting the mines in Australia since I was 18.  I wanted to see the opal mines, how they are processed, how they are priced, what they look like. I convinced my dad to drive with me 12 hours across the country to Lightning Ridge.

96%of the world’s opals are from Australia. There are no new white opals, they are from Australia and they are no longer being mined.

The color of the opal has nothing to do with the region it formed in, it has to do with the way it’s formed.

Peruvian opals – lightweight and light density makes it perfect to wear in an earring

Where do the best emeralds come from?

They are so different depending on where they are mined. There is a mine in Brazil has that intense, beautiful, almost electric blue color to it that just gives so much light and luminosity to it, it looks like its glowing. They have those deep blue/green undertones to them, as do Colombian emeralds. They have a velvety look to them because they have a lot of internal inclusions.

Zambian emeralds have more vanadium in them which makes them more yellow in undertone. Still really bright stones, but they tend to be brighter as a result because they have fewer inclusions. They generally come in smaller sizes which make them great for settings in jewelry.

Afghani emeralds, which have just come out, are such collectors’ stones.
