14K Yellow Gold Malachite and Diamond Necklace Pendant

I have been learning jewelry CAD and this is a piece I made to practice. It is solid 14K yellow gold but is not stamped as I had the design 3D Printed and cast through shapeways and they don’t stamp their precious metals. Set with genuine malachite and one genuine diamond. Only made one so it is truly a one-of-a-kind item. Chain not included. Barely charging above the cost to make. Just selling to fund this sort of expensive hobby. Important: Malachite is fairly soft and also shouldn’t be excessively exposed to water. Do not use soaps or abrasive material for cleaning. A polishing cloth is best.
