To get a quote for a certain design that you would prefer please send us a copy or sample of your desired design. We will send you a quote within  2-3 business days. Usually pricing will be based upon the number of CZ stone used, whether there is already a hole , whether the design needs to have another mold created, whether there are inlaid gold, silver etc. Upon receiving our quote and you are satisfied then we will send you a preforma invoice and a payment gateway. After we receive your payment we will commence manufacturing and will update you on how long you can expect the product. We can do design customisation using laser engraving inside and outside the ring We use Cubic Zirconia diamonds as stones for engagement rings We can also use diamonds provided by the buyer. Please note that the size of diamonds should be within 0.1 carats up to 0.2 carat only. This is because the hardness of Tungsten Carbide makes it really difficult for us to drill bigger holes. We do vacuum electroplating in any color with an additional fee of $10.00 for rings and $15.00 for bracelets We do your own brand or logo on wholesale watches you purchase from us. We can inlay gold, silver, carbon fiber, titanium, ceramic, resin Custom design can also be done with Zirconia Ceramics You can email us for more  info@cptph.com Alternatively, you can send a sample of the design to our office at: 13 Nichols Drive Mornington VIC 3931 Australia
