Get ready to bust out your wallet because this one is going to steal your heart. A phenomenal large sapphire. With only one single inclusion visible, this is a top-shelf sapphire. I get a lot of requests for larger clean sapphires, and the reality is, unless I want to cut them with flat bottoms, it isn't practical to get large yields in natural sapphire with the type of work I do. With that said, this is a rare exception. If you've been waiting for one this size, this isn't a gem you'll want pass on. The parti is clearly defined in all lighting. Its a masterpiece of naturally occuring sapphire. If your willing to wait for it, a GIA lab report is complimentary with this purchase.

This tourmaline features a gorgeous sunburst from slightly purplish Red to orangy Yellow. The color split is visible in all lighting conditions and is somewhat more or less saturated, depending on the light source. The most vibrant colors were visible in daylight. Some inclusions are visible without magnification but don't detract from its appearance. The defined color split in this gem is due to dichroism.

HOW TO ORDER

For "One-of-a-Kind" I have a selection of unique and notable gemstones on my Available Gemstones page that I have personally faceted from rare and unusual rough gem materials. I can custom make a setting to fit or you can purchase a gem loose. This selection is frequently changing, I try to add at least two new gems a week. I have a selection of pre-priced settings on my Customizable settings page for your convenience. I can also make a setting to your own specifications. I'm currently expanding my Ready To Ship Jewelry section with pre-made gold and platinum gemstone rings for those on a tighter timeline.

You can also browse my Gem Archive and see all the gems I have faceted over the years for inspiration. I have a large and well documented portfolio of past gem works.

I have a selection of "Made to Order" Gemstone and Diamond Rings as well as Ring Bands. I can make these items identical or near identical to the depicted ring in the listing photos.

This listing is for both rings, the diamond ring and the fitted wraparound band

• The center setting on the depicted ring is 9x5.5 mm in diameter. I will pick a VS clarity diamond that is closest to the listed dimensions and weight depending on what is currently available from the cutter. I pick to please!

• You will get a conflict-free VS2- VS1 Clarity diamond that is in-between 0.48-0.55 carats in weight. Exact specs will depend on what is currently available from the diamond cutter. The diamond will come with a GIA (Gemological Institute of America) grading report. A GIA serial laser inscription is available upon request, however, it won't be visible once set in the bezel.

*Please note* I do not deal in laser-drilled, irradiated or fracture-filled diamonds. All are mined & processed in compliance with
United Nations resolutions prohibiting trade in conflict stones.

They are free and you do not have to return them and they will not extend your production time. International buyers, please contact me for details on sizing prior to placing your order. Sizing it means remaking it completely and there is a $200 sizing fee for this ring.
