What quality are the diamonds? For diamonds there is a valuation model, the 4 C, sometimes extended by a 5th C: conflicts.
1. weight in carat (carat weight)
The weight of the diamond is given in carats. One carat is 0.2 g. We are happy to process individual stones of 0.1 ct or larger. A diamond of 0.1 ct has a diameter of about 3 mm and thus already quite a lot of fire. We also like to set smaller stones, approx. 0.01 ct with a diameter of approx. 1 mm, but then there should be 3 or 5 diamonds in a row. Gladly also more.
2. purity (clarity)
fllawless even at 10x magnification (no inclusions and no external flaws visible) if internally flawless except for possible surface traces from processing flawless vvs1 / vvsi very, very small inclusions inclusions are very, very difficult to detect even at tenfold magnification. vvs2 very, very small inclusions Inclusions are very difficult to see even at ten times magnification. vs1 / vsi very small inclusions Inclusions are difficult to detect at tenfold magnification. vs2 very small inclusions Inclusions are visible at tenfold magnification. si1 small inclusions Inclusions are easily visible at tenfold magnification. si2 small inclusions Inclusions are very easy to see at tenfold magnification, but not with the naked eye. pi1 Piqué I (Piquee I) inclusions just visible to the naked eye, but do not reduce the brilliance. pi2 Piqué II (Pikee II) inclusions visible to the naked eye, reduce brilliance weakly pi3 Piqué III (Pikee III) inclusions are easily visible to the naked eye and significantly reduce brilliance.
3. color (color) Diamonds that appear to be colorless to the untrained eye can be divided into different color classes by the expert:
High Fine White+ (River), GIA designation: D High Fine White (River), GIA designation: E Fine White+ (Top Wesselton), GIA designation: F Fine white (Top Wesselton), GIA designation: G White (Wesselton), GIA designation: H Light tinted white+ (Top Crystal), GIA designation: I Lightly tinted white (Top Crystal), GIA designation: J Tinted White+ (Crystal), GIA designation: K Tinted white (Crystal), GIA designation: L Tinted 1 (Top Cape), GIA designation: M, N Tinted 2 (Cape), GIA designation: O
4. cut (cut) The cut is decisive for the fire of a diamond. Thus, one can seem downright lifeless, while sparks seem to fly from the other. The following overview according to RAL 560 A5E distinguishes the following four quality levels:
Very good, excellent brilliance, few or only minor external features, very good proportions. Good (good), good brilliance, some external features, proportions with minor deviations. Medium, brilliance reduced, several major external features, proportions with significant deviations. Low (poor), brilliance significantly reduced, large and/or numerous external features, proportions with very significant deviations.
5. conflicts (conflicts)
Rough diamonds used to finance civil wars are outlawed and are increasingly entering the public consciousness as the “fifth C.” Rough diamonds without an indication of origin and Kimberly certificate are widely ostracized by dealers. There is usually no proof of origin for polished diamonds.
Are JBS diamonds conflict-free? The diamonds we set are partly recycled diamonds – i.e. gemstones that have already been worn in jewelry – and partly stones that we source from Indian cutters, where care is taken to ensure that the cutters receive a fair wage and child labor is excluded. In addition, the diamonds are subject to the Kimberley Process, which ensures that they do not originate from war zones; incidentally, this applies to all diamonds offered for sale in Europe.
Does JBS offer colored diamonds? We offer diamonds in the naturally available colors. The beautiful cognac, harmonizes especially with red gold, the slightly rarer olive looks great in white and yellow gold. Champagne colors tingle everywhere, that’s what the name says…
What we do not offer are subsequently and artificially colored or heated diamonds. This happens mainly in nuclear reactors and we don’t find it a nice thought to use their finger as a decay pool.
