While the industry is much improved on guaranteeing one's diamond is a legitimately sourced non "blood" diamond via the Kimberly Process agreement, it is not quite to the point of specifying mine or locale of origin with few exceptions. (an exception is diamonds mined in Canada are many times marketed as such and are sold at a slight premium for their pedigree) While we believe we are only a few short years away from specifying origin on most diamonds, we are not there yet.

We buy from site holders that buy rough diamonds. For years De Beers has been forbidden to do business directly in the US due to anti trust issues and other practices. As they have been allowed to operate retail stores under one of their subsidies in the US they have been forced to modify their actions for the better for more than a decade.

The highest probability is that the diamond originated from the continent of Africa as this area remains the world's leading producer of the highest quality rough (uncut) diamonds. If the diamond chosen is colorless, there is a secondary chance that it came from Russia, but their production is much less than Africa as a whole. Once mined it most likely was cut in India, who now cuts 75% of the world's rough diamonds. In round brilliant diamonds the Gemological Institute of America (GIA) now has standardized five grades of overall cut.

This we can assure- the diamond was responsibly sourced- a diamond from M Lemp Jewelers is not a 'blood diamond'. While not speaking to origin, the other thing we are confident in- your diamond will be incredibly brilliant! This has been our reputation since 1890.

  • Carat Weight
  • Color
  • Clarity
  • Cut

Carat is the unit in which a diamond is weighed. One carat equals to 0.2 grams or 200 milligrams. Carat weight is the prime factor that determines the weight of a diamond. Larger diamonds are undoubtedly costlier. Carat makes expressing diamond weight easier as compared to milligrams. Instead of giving three labels to diamonds weighing 20 milligrams, 211 milligrams and 220 milligrams, carat offers a category for fitting the diamonds in a one category, placing these diamonds in one-carat range.


One should not forget that high carat weight does not necessarily mean a larger looking diamond. Even diamonds of the same weight can differ on a basis of other factors, especially cut that influences perceived size. Large diamonds are rare to find and much in demand as compared to small diamonds even of the same quality. The price of a one-carat solitaire diamond ring is more than a ring with smaller diamonds making up the same carat weight. Diamond comparison is not effective until you compare the diamonds of similar features and qualities. While comparing the value of different diamonds, divide cost of every diamond in accordance with the carat weight and then calculate its price per carat.

You may have witnessed your jeweler discussing points while talking about diamond sizes. This is not in context with the number of facets a diamond has but to the weight of the diamond. One carat is equivalent to 100 points, so every point is 1/100th of a carat. Carat weight also influences a diamond’s price. Because of the rarity of larger stones, they are priced higher. Carat weight is an important consideration while buying the diamonds for your-self.
