Gemstones Cut By Us

We are very excited to present this beautiful update of our custom cut and hand carved gemstones.  This update contains some of the finest gems to have come out of our shop.  Faceting large gemstones requires much hard work and patience, and even more so with hand carved gems because they first must be faceted, then carved and finally hand polished to give them their unique appearance.  All of these gemstones were cut from hand selected, high quality gem rough.  We strive to create fine quality, amazing and unique custom gemstones that are seldom seen on today's market.   All of the stones on this page were faceted by Allyce and Brett Kosnar.  All of these gems can be made into a custom pieces of jewelry by Brett Kosnar, upon request!

Comments:

Here is a dazzling Heliodor gemstone from our shop. Heliodor from Volodarsk-Volynskii is some of the most beloved and classic Beryl extant. Good gem material is scarce due to the fact that this locality has not produced any good specimens in years. There is a small, yet notable, "Horse Hair" inclusion in this stone that is indicative of Heliodor from the Ukraine, otherwise the gem is amazingly clean. The outstanding brillance, great clarity, and large size of this stone make it a great collector's gem, for sure!  This gem was facted by Allyce Kosnar.

Comments:

This stone has half sphere shaped "bubbles" that were hand carved into the pavilion. The gem has amazing clarity, and the carving on the bottom makes it really "stand out" from other Citrine gemstones. Hand carving a stone can be very time consuming, requiring much control and patience, but as you can see it is well worth it for the end result. We are hoping to bring you more of these hand carved gems in the future. This stone was faceted and hand carved by Brett Kosnar.

Gemstone # LEMONBRAZ4280
Name: Lemon Quartz
Locality: Brazil
Weight: 42.80 carats
Size: 27.97 x 18.55 mm
Price per Carat: SOLD
Price For Stone: SOLD
      Cut: Modified Cleopatra's Eye
Color: Yellow
Clarity: Eye Clean
Cut by Us: No
Availability: sold

Comments:

The cut on this stone is called Cleopatra’s Eye because as you can see it resembles a human eye. The half sphere "bubble" that was hand carved in the center of the pavilion, really finishes off the stone because it gives the appearance of a retina. This gem has great clarity and flash. The beautiful lemon yellow color is obtained by heating the Quartz, no damage is done only the color is enhanced. I truly have not seen another cut like this, and it really becomes more of a conversation piece than just a gemstone. This stone was faceted and hand carved by Brett Kosnar.

Comments:

Tourmaline from Afghanistan has risen drastically in price over the past two years, making top quality rough more difficult for us to acquire. With the Tourmaline market on the rise, stones like this will be very difficult to acuiqre for reasonable prices in the near future. This stone has a gorgeous, deep sea foam green color that shimmers throughout the gem. This stone was faceted by Allyce Kosnar.

Price For Stone: $ 1006.00
      Cut: Portuguese Trillion
Color: Orange, Red and Blue
Clarity: VSI
Cut by Us: yes
Availability: Available

Comments:

10 carats is rather large for a red Sunstone gem from Oregon. This stone is red throughout and saturated with “shiller” (copper inclusions) which is highly desirable in Sunstone from this locality. There is also a blue stripe of color that travels through the middle of the stone making for one of the rarest color combinations for Oregon Sunstone with both red and blue together. We really enjoy cutting US gems and Sunstone is one of our favorites, we hope it will be yours too. This stone was faceted by Brett Kosnar.

Gemstone # SUNOREG950
Name: Sunstone
Locality: Oregon
Weight: 9.50 carats
Size: 16.48 x 11.78 mm
Price per Carat: $ 100.00
Price For Stone: $ 950.00
      Cut: Modified Custom Pear
Color: Red and Orange
Clarity: VSI
Cut by Us: yes
Availability: Available

Comments:

The red color and brilliance of this stone come off well with this pear shape cut. This stone is red throughout and saturated with “shiller” (copper inclusions) which is very common in Sunstone from Oregon. Good quality Sunstone rough has become harder for us to find due to the market price increase and the abundance of poor quality rough that has flooded the market in the past few years. So we have to be very selective when we are choosing rough to be facetd for our inventory. This stone was faceted by Allyce Kosnar.
