I've designed this entirely in sterling silver, and everything is handmade and created into a Celtic Trinity Knot pendant necklace with an 8mm gemstone of your choosing, which is set in a heavy 4 prong setting. The lab-created gems are blue sapphire, emerald and Tanzanite which means they were created in a laboratory environment, but with the same exact chemical properties as earth-made ones, but without the same expense. The base of the pendant is made with a total of 5 Trinity Knots and sterling wire work braids down the center to add the balancing touches to the piece. The sterling silver box chain is soldered to each end of the pendant. The size, of this piece, is approximately 2.75 inches in length and 2 inches in width - the 16 inch box chain makes a total of 18 inches approximately. The piece will be rhodium plated to protect from tarnishing! Please allow me 5 days for fabrication of your new piece. It will come in a small jewelry box within a felt pouch for safekeeping. Please convo for questions! Thanks for looking!
