Diamonds:

o  A diamond's value is based on four criteria: color, cut, clarity, and carat.

o  The clarity and color of a diamond usually are graded.

o  Scales are not uniform: a clarity grade of "slightly included" may represent a different grade on one grading system versus another, depending on the terms used in the scale.

o  Make sure you know how a particular scale and grade represent the color or clarity of the diamond you're considering.

o  A diamond can be described as "flawless" only if it has no visible surface or internal imperfections when viewed under 10-power magnification by a skilled diamond grader.

o  Diamond weight usually is stated in carats, with its weight described in decimal or fractional parts of a carat.

o  If the weight is given in decimal parts of a carat, the figure should be accurate to the last decimal place. For example, ".30 carat" could represent a diamond that weighs between .295 - .304 carat.

o  Some diamonds may be treated to improve their appearance in similar ways as other gemstones.

o  Imitation diamonds, such as cubic zirconia, resemble diamonds in appearance but are much less expensive.

o  Certain laboratory-created gemstones, such as moissanite, also resemble diamonds and may not be adequately detected by the instruments originally used to identify cubic zirconia. Ask your jeweler if he has the current testing equipment to distinguish between diamonds and other lab-created stones.

Diamond Facts:

- Diamonds throughout history have been the symbol of love and romance.  Like true love, a diamondís brilliance strength will not diminish with time.

- The word diamond originates from the Greek "adamas," meaning indomitable, as diamonds were believed to offer protection and power in the face of danger.

- The earliest written account of diamonds dates back to around 500 BC and the first recorded use of a diamond in an engagement ring was in 1477 with the engagement of the future Holy Roman Emperor Maximillian to Mary of Burgundy.

- In the 19th century,  with newly discovered mines and developments in diamond cutting and polishing, the solitaire engagement ring was introduced.

- The Tiffany mounting, presented in 1886, made the most of the diamonds brilliance by raising it up from the band. The design allowed greater amounts of light to enter the gem, allowing it to exhibit its utmost brilliance.

 

Current Natural uncut diamonds

These are all very nice specimens for a mineral collector or very unique gift!

According to De Beers, many mines in the world average about 0.4-0.5 ct per stone. However, the number of stones larger than 1 ct (0.2 g) produced at mines is very small (approximately 400 000 stones per year) and, in carat terms, represents only about 0.5% of the total carats produced in the world.

Most mined rough diamonds are small and, to put this into perspective, a 10-ct rough octahedron crystal, which is considered to be a large stone, has a side that measures only about 10.5 mm, while a 1-ct stone has a side that is close to 5 mm and a 0.5-ct stone has a side that measures 4 mm.
