Why Buy Loose Gemstones Instead of Pre-Set Jewelry?
 
There are many reasons, but basically it boils down to value and choice...

When buying your danburite gemstone loose instead of a pre-set stone, you can be sure you are getting the best value for your money.  Loose gemstones are less expensive, a better value, and you can really see what you are paying for.  The most important part of getting the right price and finding the best value is to first see what you're getting.  A jewelry setting will hide the inclusions inside a gem, and can deepen or brighten its color.  With a loose stone you can much more easily inspect the gem and see it for what it really is.  In this way you can get a better idea of its true worth and be sure you are paying a fair price.

The second advantage of buying a loose gemstone is choice.  You are free to pick the exact color, cut, shape and variety of the stone for the setting of your dreams, be it yellow gold, white gold, platinum or silver; prong set or bezel set with diamond accents.  You can experience the joy of creating your very own, one-of-a-kind jewelry design. Choose from a variety of jewelry settings and styles to create a completely original presentation that will perfectly suit your individual gemstone and will be as unique as you are!

Danburite is a Calcium Boric Silicate, and is rated at 7 on the Moh's Scale of hardness.  Danburite is an excellent gemstone for all jewelry applications due to its toughness and lack of cleavage. Danburite tends to be more common in small sizes with well cut stones displaying bright colors, ranging through colorless, yellow, tan, and occasionally pink. Loose danburite is loved and revered by gem collectors not only for its durability, but also for its brilliance that rivals even that of Topaz.

General value guidelines apply to Danburite, with larger, cleaner, brighter colored stones naturally being more valuable. It should be noted however that a clean, colorless stone with exceptional brilliance would surpass a pale yellow or slightly pink stone in terms of per carat value.

Danburite has a specific gravity of 2.80. Refractive indices range around 1.627 - 1.641. The refractive index (RI), measured using a refractometer, is an indication of the amount light rays are bent by a mineral. Birefringence is the difference between the minimum and maximum RI. When birefringence is high, light rays reflect off different parts of the back of a stone causing an apparent doubling of the back facets when viewed through the front facet.

Most gems have a crystalline structure. Crystals have planes of symmetry and are divided into seven symmetry systems. The number of axes, their length, and their angle to each other determine the system to which a crystal belongs. Danburite gemstones crystallize in the orthorhombic crystal system. Crystal Habits include generally prismatic crystals with a diamond-shaped cross-section. The termination is a steeply slanted dome producing a wedge look. Danburite crystals can be rather thin to almost acicular or up to a foot long and several inches across.


Color

The color of Danburite is most commonly clear to white but it can also be found in yellowish to brown or greenish.  Light pink or yellowish danburite stones are more rare and expensive.


Cut

Because of Danburite's hardness and lack of cleavage, it can generally be cut into most of the common gemstone shapes/cuts, such as rectangular or square cuts, rounds, pears, ovals, emeralds, cushions, and many more.

Danburite occurs in metamorphosed carbonate rocks and in granites associated with hydrothermal activity.  It is also found in evaporites.  The deposits of Danbury, Connecticut have long been covered over and made inaccessible due to the large community that has grown over the years. Today, loose danburite deposits are found in Japan, Madagascar, Mexico, and Myanmar (Burma). Mexico is today's most important source of gem-quality Danburite.
