(1) How many stones are in the design?
(2) What type of metal is being used? (ie. White Gold, Yellow Gold, 2 Tone Gold, Platinum...)
(3) How detailed is the design?
Keep in mind that if a ring design is quite intricate or has more than one stone to set, it will require more time to finish. As a rule, solitaire designs (one stone only) typically require 3 weeks to complete from wax to finish. A multi-stone ring or 2 Tone Ring can require 4 to 6 weeks to complete; however, it is also dependent upon the amount of custom designs your Professional Jeweller may have at that given time.
In order to have quality work done, it is always a good idea to consult your Custom Design Specialist well in advance of the date that it is required so that you may be able to get proper advice and guidance in order to allow time to tweak the design, if necessary. It has been known in some rare circumstances, your Jeweller may be able to produce a sample ring for you to present and then design it according to your specific requirements at a later date.
