Stones We Work With

We go to great lengths to make sure we are only sourcing sustainably and ethically sourced gemstones and diamonds. See below for more detail on the type of stones we can provide: diamonds, precious gemstones, moissanite and semi-precious gemstones.

DIAMONDS

TYPE DIAMONDCANADIAN DIAMONDSCOLORED DIAMONDS
ABOUTThe quality of white diamonds is based off of the 4 Cs. Please see Diamond Shapes and 4 Cs for more details. The quality of white Canadian diamonds is also based off of the 4 Cs. Please see Diamond Shapes and 4 Cs for more details.Colored diamonds are a great option for those who appreciate the 10 on the MOHS hardness scale, but are looking for a different color than the classic diamond.
QUALITYWhite diamonds are a 10 on the MOHS hardness scale, making them an excellent choice for an engagement ring. Canadian diamonds are a 10 on the MOHS hardness scale, making them an excellent choice for an engagement ring. The most important factor when it comes to the value of a colored diamond is the color intensity. Carat weight is the second most important attribute, while cut and clarity are less important when determining the value of a colored diamond.

ORIGINThey are found primarily in Congo, Australia and Russia. They are found in the Canadian provinces. Canada has implemented sustainable mining practices, making them an ethical choice. They are found primarily in Australia, India and South Africa, but are also prevalent in Venezuela, Guyana, Brazil and Indonesia. 
FUN FACTThe name diamond is derived from the ancient Greek word meaning “unalterable,” “untamed” and “unbreakable.”     Canadian diamonds weren’t discovered until the early 1990s. Colored diamonds are much more rare than white diamonds. Only one in every 10,000 diamonds possesses natural color. 

PRECIOUS STONES

TYPE SAPPHIREMONTANA SAPPHIRESRUBIESEMERALDS
ABOUT &
TREATMENT
Approximately 95% of the sapphires in the world have been heat treated. The 5% that aren’t heat treated are very rare and valuable. The heating process improves the color, clarity and overall appearance. They come from three places in Montana making them a very ethical choice for a stone. They are all heat treated and this doesn’t require any special care. Rubies come from several places around the globe, including Sri Lanka, Afghanistan, Thailand, Australia, Cambodia and Brazil.  Most rubies are treated in some way and heat treatment is most common.While emeralds are found all over the world, the majority of them come from Colombia. The next largest producer is Zambia. Most emeralds are oiled as part of the post-lapidary process. This needs to be disclosed when buying an emerald as oiled emeralds aren’t as valuable as non-treated stones. 
QUALITYQuality is based off of color, clarity, inclusions, transparency, cut, weight, and origin.Quality is based off of color, clarity, inclusions, transparency, cut, and weight. Quality is based off of color, clarity, inclusions, transparency, cut, weight, and origin.Quality is based off of color primarily and clarity (high transparency) as a close second, cut, and carat weight.
DURABILITYSapphires are a 9 on the MOHS hardness scale and therefore a great option for an engagement ring.  Montana Sapphires are a 9 on the MOHS hardness scale and therefore a great option for an engagement ring.Rubies are a 9 on the MOHS hardness scale and therefore a great option for an engagement ring.  Emeralds are a 7.5 - 8 on the MOHS hardness scale, making them somewhat soft for an engagement ring. Our advice: Make sure to insure your emerald ring so it is covered if it cracks. 
CAREClean your sapphire with warm water, a soft brush and any detergent. Clean your Montana Sapphire with warm water, a soft brush and any detergent.  Clean your ruby with warm water, a soft brush and any detergent.  Clean your emerald with warm water, a soft brush and mild detergent. 
FUN FACTSapphires come in every color of the rainbow! If you’re looking for something a little more unique, ask us about the colors we can source. Some of our favorites have been a teal blue color. They were used in a line of Tiffany and Co. jewelry in 1900. They come in very small sizes making them perfect accent stones and can be found up to a 2 carat size, but the larger sizes are much more rareRubies come in many shades, but the most valuable are bright red and are referred to as “blood-red” or “pigeon-blood.” The Sunrise Ruby is the most expensive ruby and colored gemstone in the world. It sold in 2015 for $30 million. Unlike diamonds that are graded with a x10 loupe, emeralds are graded with the naked eye. 

SEMI-PRECIOUS AND MOISSANITE

Here are some of the most common semi-precious (and moissanite) we have worked with. Have another stone in mind? Let us know and we can most likely find it for you!

TYPE MORGANITEAQUAMARINEMOISSANITE
ABOUT &
TREATMENT
Morganite is typically heat treated and occasionally irradiated. Aquamarine is typically heat treated. Moissanite is a patented gemstone that is lab created. 
QUALITYWhile there isn’t a grading scale for morganite, the quality is based off of color, hue and tone.  While there isn’t a grading scale for aquamarine, the quality is based off of color (a light blue/green), hue, tone and transparency. Moissanite is a 9.5 on the MOHS hardness scale, making them a great alternative to the traditional diamond.
DURABILITYMorganite is between 7.5 - 8 on the MOHS hardness scale and therefore a somewhat less durable option for an engagement ring.  Aquamarine is between 7.5 - 8 on the MOHS hardness scale and therefore a somewhat less durable option for an engagement ring.  Labs have created a stone that almost has the same hardness of diamonds and with greater refractive properties. This has allowed customers to get the look and durability of a diamond without the cost or environmental and ethical issues. 
CAREClean your morganite with warm water, a soft brush and any detergentClean your aquamarine with warm water, a soft brush and any detergent.  Clean your moissanite just like you would clean a diamond, with warm water, a soft brush and any detergent.  
FUN FACTMorganite was named after financier JP Morgan. Hey Coloradans, aquamarine is the official stone of Colorado.   More than 120 years ago chemist, Dr. Henri Moissan, discovered moissanite (silicon carbide) in a meteorite crater. Since then, scientists have patented a pure silicon carbide to reproduce what is found in nature.
