Frequently asked questions
How is the price of gold jewelry set?
Karat, weight, stones and workmanship set the price. Because the gold price changes daily, quotations are dated and prepared per project.
Can the same design be made in different karats?
Yes. The same model can be produced in 9K, 10K, 14K or 18K; weight and colour tone change with the karat.
What do you need for a quotation?
An image or drawing of the design, the karat and colour, stone details, estimated quantity and target market. Send them through the quotation form.
