Gem 1023 - Lilac Sapphire - 1.03 ct. A very pretty lilac color stone from Tanzania. I cut this on in the "Super Nova" design, a design that's been around for years. It works well on smaller stones since the pavilion facets are rather large. The stone measures 6.92 x 5.95 mm, and has excellent crystal. There are a few small bubble type inclusions that you don't see with the naked eye, and on the left side widest part of the girdle a "natural". This was a small section that didn't quite cut out with the rest of the girdle, but I didn't want to make the stone smaller to clean this up. It's really not noticeable, and if the stone were bezel set would be completely covered. I have discounted the stone due to this, so I think it represents a great value for it's size and color. The stone is all natural with no treatments.

Gem 1022 - Montana Sapphire - 1.42 ct. This golden orange Montana sapphire is from the Missouri River bed. The stone has been heated which intensifies the color. The stone measures 6.4 mm and is cut in a SRB design that is slightly modified to create larger facets, and I added a small step to the pavilion to increase the color. These orange Montana stones have a color zone that is centered in the stone. When viewed through the table the color fills the stone, however when you look from the sides you will see the ball of color in the stone. You can see this in the pictures below. Makes for a unique and interesting stone.

Gem 124 - Blue Sapphire - 1.01 ct. This is a dark blue sapphire from Nigeria, that is all natural, no heat or other treatment. The stone is dark, similar to what you see in a mall store. It's priced accordingly. I noticed this one in my gem case, and realized it was never up on the site. I cut this stone maybe 5 years ago.
