You would not think that rocks can be sexy, seductive, elegant, graceful and feminine! Would you? Well, it is a bit different if we are talking diamond “rocks” as in this necklace: 
Diamonds naturally crystalize in cubes and these little grey diamonds in the rough are each drilled. A tiny gold wire (28 gauge) is then inserted through the diamond and balled up with a minute flame from an acetylene torch and attached to a fine and elegant 18 karat gold chain. Since the flame comes so close to the diamond, this will heat up the diamond to a very high temperature. This technique can only be used with diamonds because other gems are less heat tolerant. Never the less, occasionally a diamond will zing!! That’s when it splits and the pieces fly through the studio!
Because the diamonds are in the rough, there is an organic quality to this necklace. Sometimes I get comments such as “exquisite”, “sophisticated” and “charming”. But what I really think: this was a huge “labor of love”.

Such an elegant and natural treasure! But, yes, I’m sure with the delicate details, this piece must have been a tedious endeavour…well worth it though! :-}
thanks.
