how is settled down the prices of the  Mediterranean's red coral?

the criteria are four

1°)absence of hole

2°)perfect sphrese

3°)dense and uniform color

4°)the color

another important point: where and from who to buy

from 1600 the most important city in the world for quality an quantity producion is Torre del Greco(Naples-Italy)

there are undred handicraft laboratories , where this art is handed on of father in son. 

Price: perfect sphrese , darke color(like bloode) , uniform , we are in front of the perfection ,  AAA QUALITY .

AAA QUALITY:diameter  3mm to 4,5 mm     3.5 - 4 euro for gr. 

                           diameter  5mm to 6mm       6  euro   "

                               "        6mm to 7mm     8.5 euro         "

                              "         7mm 7.5mm       9.5  euro             "

from the 8 mm to up the price is subject  to multiple factors and can oscillate of vary to you euroes  for gram .

we can say sure that one 8mm necklace can't to cost less than 600 euroes , if the price is 500/550 if possible but if the cost is 200 or 300 euroes we can be sure it isn't MEDITERRANEAN RED CORAL(CORALLIUM RUBRUM) but it is a copy or Bamboo-coral(white deid coral) colored . or white Tridacna-shell .
