Being the first to reply, if I read your message correctly...you have two (2) Akoya pearl bracelets made up of 7mm "Hanadama" quality pearls. My first questions (before being able to provide an opinion of the 'appraised value') would be;
- are the pearls 6.5-7mm or 7-7.5mm in size?
- what is the length of the bracelets (or the number of pearls on each)?
- are the pearls certified as Hanadama, or is the seller simply claiming this?
- I assume the clasps are at least 14k gold...but what type and size are they?
- a clear picture of each would be most helpful.
As for insurance - in the event you ever need to replace the items...most people have an incorrect assumption about the process. The appraisal certificate provides you with something to provide the insurance company in the event the item needs to be replaced...but the insurance company won't simply hand over the value indicated on the certificate.
Depending on how long ago the certificate is dated, the insurance company will take the appraisal to their own appraiser to get an up-to-date version of it...which depending on the economy, price of gold, adjustment for inflation, assumption of the condition of the jewelry based upon expected wear...is often less.
Also something to keep in mind is that a lot depends on where the appraisal is from. Appraisals coming from company's based in China are often considerably higher than appraisals from Canada or the USA. Appraisal values can also vary by as much as 30% as well depending on who has done the appraisal...such as a jewelry appraiser, versus a pearl appraiser...as well as how the appraisal value is determined (especially if computer software is used).
For instance, appraiser's using "The Gem Guide" appraisal software often have pearl appraisal values on the high side because they reference pearl wholesale prices from American wholesalers...and because their software uses has more grade levels within each of the 7 quality factors...like for the roundness of the pearl, the options are very off-round, off-round, slightly off-round, very slightly off-round, mostly-round, and all-round...as opposed to the GIA's off-round, near-round and round terms.
(if I've misrepresented any information here...please someone correct me).
