There is a lot of unhelpful advice out there, which seems to result in people arriving here with the same questions time and again. Using jojoba wonít help with causing your fragrance to mature faster, but it will cause it to go rancid eventually because jojoba goes off. Ethanol does not go off and that is one of several reasons itís the top choice as a perfume base.
Also you can make an oil based perfume with jojoba (or better with an oil that does not go off such as DPG, or fractionated coconut oil) but it wonít make an Eau de Toilette - the effect is quite different.
The best way to improved the speed with which you can produce a fragrance is to pre-dilute your ingredients in ethanol and blend them that way. Youíll still find the resulting blend improves over the first few days and weeks, but the biggest change takes only 24 hours or so.
Final thought: the questions you are asking suggest that you may not be ready to start making a commercial product - the regulatory and safety issues you need to understand are way more complex than anything weíre talking about here - rather than try to learn to be a perfumer yourself in a short time, why not collaborate with a perfumer to make the Eau de Toilette for you to go with your jewellery?
Over time you might learn to make it yourself if you are keen to do that, but if you want something now I think you need some professional or at least semi-professional help.
Hope that helps
