59 Carats Gemstone Mezezo Rough
I view the opals for hours to obtain the best looking stones, once I choose the stones I make the purchase, this can tie up hundreds or thousand of dollars for weeks before you see your stone.
You truly don't know the condition of your opals until you have them in your hand, this is where you evaluate the value of each stone. See all the cracks and how deep they go and if it is all through the stone, how much rock and clay is on the outside, how many carats do lose? how much of the opal is dead material. Rule of thumb is the natural cutting loss,
I will have between 12 carats up to 20 carats remaining after all is cut away and that rule isn't always correct either. The price of this rough is $3540 usd and is valued in the rough at $60 a carat, Between 60% and 80% will be ground away and yes you pay for the ground material.
I would maybe get 6 stones and they will be about $590 each, then comes grading and that changes everything. If I hit the pattern right and gave you a harlequin pattern and extra colors that brings the price up considerably.
