Received an inquiry from a customer on December 19, 2023, requesting to customize a cool pendant. Because the client is a designer themselves, they have very clear requirements for the pendant they want. Based on a series of communications, the final order is confirmed and the design of 3D drawings begins. The 3D design model made according to the customer's requirements was not confirmed at once because the customer wanted the effect of full moissanite inlay, but the pattern he provided was hollow and could not meet the condition of full moissanite inlay. We made a second change based on the customer's expected effect, trying to achieve full moissanite inlay while keeping the shape of his logo uncovered. Black moissanite were also inlaid in the large hollow areas of the eyes, nose, and mouth. After the second 3D rendering, the pattern and stone inlay effect of the pendant were satisfactory, but the buckle of the pendant needs to be modified again. After the customer's confirmation, we carried out the third round of 3D design drawing modification and ultimately achieved the customer's satisfaction. Then the production of the pendant began, and semi-finished products were sent to the customer to update the progress of the pendant. The customer expressed great anticipation. After the pendant was completed, a video and photos were sent to the customer for confirmation. The customer randomly arranged for the final payment and then packaged and shipped it. The customer received the pendant and expressed great liking for it.
