A Brilliantly Goldia Diamond Engagement Ring Design and Manufacturing Process

	This Goldia ring is an excellent design for 14k gold with heavy, low-profile prongs for the 1.50 carat center diamond, ample wall thickness for setting the baguettes and supporting the overall structure and sufficient room for bead setting the small round diamonds and bright cutting along the sides. This ring mounting is an ideal example for an overview of step-by-step gold manufacturing techniques.
	The original model is made with some shrinkage taken into consideration. Only after a model is perfected and tested, is it introduced into the Goldia line. For this piece, technicians at Goldia calculated about 1% or less shrinkage from the original model to the finished replica cast in gold. They attribute this to the use of silicone for their molding procedures. This is especially important for setting tolerances (depth, width and size of bearing walls) for the channel set baguettes and bead set rounds with bright cuts. This wax was injected into a silicone mold. After it solidifies, cools and removed from the mold a wax model specialist examines it, removes the parting lines and other surface inconsistencies and then prepares it for casting.
	The main gate or sprue is about 4.5 millimeters in diameter and attached at the heavy shank on the bottom portion of the ring. For this model, 2 additional 1.8 millimeter feeder sprues are attached within the finger hole below the top. These additional sprues assist in quickly feeding the gold to the heavier upper portion of the ring since the metal is quick to solidify. Research in gold casting has shown that strategically placed multiple sprues are a key factor in successful progressive solidification (the metal cooling and solidification) and reduces or eliminates porosity and cracking.
	Goldia uses a large button tree structure for casting multiple pieces. This image shows how the main and runner sprues are attached to the casting base. More pieces will be attached to the button to complete the 'tree'.
	The gold is melted by induction and is protected by argon to reduce its exposure to the atmosphere. When molten, gold absorbs considerable amounts of oxygen and hydrogen. The argon works as a cover gas because it is heavier than air and shields the molten metal from the atmosphere. The Goldia casting expert opens the chamber and carefully stirs the molten metal with a quartz rod to insure distribution of the elements. After, the chamber is secured and the pieces are cast.
	The arrow indicates the project example on the casting button structure. Progressive solidification is a general description for the metal cooling and solidification cycle within a cast mold. Essentially, the metal should cool and solidify from the top of the tree (where there is a lesser quantity of molten metal) toward the button. The modified tree structure, feeder sprues and proportionately large button size help to insure success in this critical process. 1. Gold, like other metals shrinks after solidification. Because all models are connected directly to the largest mass of molten metal, there is an assurance that all models will have cast completely and begun the solidification process well before the button solidifies. 2. Gold characteristically releases considerable gasses (which it absorbed in molten state) during solidification. The feeder sprues in this structure not only allow for efficient flow of molten metal into the model, but also provide additional venting for the release of gas. A thinner button would have solidified first causing the shrinkage and gasses to be trapped within the jewelry models causing pitting, porosity or incomplete or misshapen castings. Eliminating the feeder sprues would also jeopardize the success of the models with through-and-through porosity from trapped gasses.
	After casting, the Goldia pre-finishing department removes the sprues and gates by sawing.
	The remainder of the sprues is removed by filing and sanding. The ring is then rounded and overall pre-finishing begins.
	For pre-finishing, the Goldia technician uses rubberized abrasives to smooth the inside of the ring. Sanding sticks, files and other abrasives are used on the outer surfaces. Because the cast models are free of pitting, there are no problems in the pre-finishing process. The ring is then sent to the polishing department for pre-polishing prior to setting.
	With the pre-polishing completed, the ring goes to the in-house stone setting department where the diamond baguettes are channel set. Opposing bearings are cut in the gold side walls with a bearing bur. The baguettes are then "slid" into place from the top portion of the ring. There was no porosity in the model to interfere with the setting process. This image shows the baguette setter burnishing the sidewalls with a fine pointed burnisher.
	For the final tightening, the setter uses a reciprocating hammer. The hammer is set to the lowest setting and provides sufficient impact for final tightening.
	With the baguettes secured, the next step is the bead-and-bright-cut setting of the round side diamonds. The small round holes are made larger with a round ball bur that is about the same diameter of the diamonds being set. The diamonds are seated with a 0.10 millimeter spacing between them. The stone setter completes the setting of the small rounds. Again, because this model is porosity-free, the setter was able to raise substantial, consistent beads to secure the diamonds with no problems.
	Next the large round center diamond is set. The first step in this process is to reduce the dimension of the upper gallery wire with a large round ball burr.
	Next, a 90 degree bearing burr is used to create the bearings in each of the 4 heavy prongs individually. The metal flashing created by burring is removed and the diamond is set using pliers and then secured by hammering for final tightening. With gold's desirable malleability, the prong bending and forming was trouble-free.
	After setting the ring is sent to the polishing department for final finishing and polishing. This mounting is ideal for gold due to the following desirable features: The center diamond is set at a moderate height and in heavy prongs which will remain secure through normal wear. The four center diamond prongs are supported by a sufficient upper gallery wire. The wall thickness of the channel walls was ample enough so that after the bearings were cut for the baguette stones the thickness that remained was substantial for setting and support of the ring structure. The setting area for the small round diamonds allowed for enough metal to grave significantly-sized beads that will secure the stones during normal wear and to apply an attractive bright cut to reflect their brilliance.
