|I sorted my diamonds and selected the very best below. These were graded
at a distance, assessing the brilliant luster and clarity, that give them
a commanding presence and sparkle. These stand out from all of the rest and
are suitable for use in jewelry, uncut, as-is. I am offering this assessment
in response to a request from a jeweler that wanted to know which diamonds
were my best. These are not my biggest, though several are among my most
expensive, but they are worth it.
No-questions-asked return policy.

If you are considering buying a diamond for use in jewelry,
here are some following suggestions:
In general, add 50% to the carat weight for an uncut diamond because they
are more bulky than faceted diamonds. A 1.00 carat brilliant-cut
faceted diamond is 6.4 mm in diameter around the girdle. A similar
sized 6.5 mm uncut diamond will be in the 1.5 carat range.
The exception to rule number 1 above is a macle diamond.
These are triangular diamond crystals that are the result of crystal twinning
and they resemble triangular trillion-cut faceted diamonds. Because they
are shallower than comparable uncut diamonds of equal weight, they appear
much larger for a given carat weight. A 6 mm (on each of the triangular edges)
macle diamond will weigh approximately 1.00 carat.
Look for a diamond crystal with natural sparkle - lots of
small reflections of light caused by the crystal faces bouncing light internally
throughout the crystal. Some diamonds have flat, planar faces (glassies)
and look dull. Other diamonds have a satin-like surface luster that is often
attractive, but kills the internal sparkle. The best crystals for natural
diamond jewelry will have complicated crystal faces with striations, trigons,
or simply a unique shape that gives them an internal sparkle.
All diamonds on this page were selected for their
Consider the the color of the surrounding setting when selecting
the color of the diamond. It is best to contrast yellow or brown diamonds
with a white metal such as platinum, titanium or white gold. Yellow gold
settings look best with green, red, white diamonds.
Work with your jewelry designer when designing the final setting to determine
the best orientation for the crystal. Rough diamonds are asymmetric and
appearance can vary greatly depending on which faces you are looking through.
Identify the best faces and then design the setting accordingly. Be orienting
the diamond properly you can hide inclusions/flaws, enhance the color, and
get maximum sparkle.
This is the gallery of my natural
diamond crystals for use in jewelry . These uncut rough diamonds are crystals
with natural sparkle making them perfect for use in jewlery without faceting.
These are real diamonds that gemstones are made from - not Herkimer Diamonds
that are common quartz.
Using rough diamonds in jewelry is a major trend in jewelry today. Of course
the practice of using raw diamonds dates back at least to Roman times when
they were commonly found in men's rins. But recently major diamond jewelry
companies have created their own lines. DeBeers introduced their line called
Talisman in 2006.
A new company Diamond in the Rough
introduced a large 305 carat rough diamond necklace was prominantly feateued
in Neiman Marcus 2007 Christmas Book for $1 million.
The success of these top teir jewelry companies marketing rough diamond jewelry
has created demand from independent jewelry designers that are interested
in the lower overhead cost possible because the expense to have each diamond
faceted by a mester diamond cutter has been eliminated.
All diamonds sold on this web site were purchased from legitimate sources
not involved in funding conflicts and in compliance with the United Nations
Kimberley Process requiring all uncut rough diamonds to be sealed in tamper-proof
containers at the point of origin to prevent smuggled conflict-diamonds from
tainting the shipment, and a Kimberley Process Certificate is on file at
the U.S. Department of Commerce. The owner, John Betts, hereby guarantees
that these diamonds are conflict-free, based on written warranty of Kimberley
