Natural Diamond Crystals for Jewelry - Uncut Rough Diamonds For Sale
Crystals with natural sparkle making them perfect for use in jewlery without faceting

Below is a 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.

If you are considering buying a diamond for use in jewelry,
here are some following suggestions:

  1. 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.

  2. 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.

  3. 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 natural sparkle.

  4. 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.

  5. 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.
