This opal was appraised by an independent master valuer for $1,145 Canadian ( $950 US funds.at time of listing ) retail replacement value. (Steven Knight, GG,R.M.V.,CJA-CAP. ) A copy of the appraisal unsigned and unsealed included at no charge. If you want a signed ,sealed copy for insurance purposes, one can be sent to you for an additional $25. Master valuers are THE experts on coloured stones, and signed sealed appraisals from them are accepted by insurance companies as verified retail replacement value. Opal is an alternate birthstone for those born in April and October. One of my favourite gems. My price is determined by what I had to pay. Some I have had for decades.

Supply and demand rules in true gem buying as in every other human investment.
Each earth mined gem is a unique work of art, unlike the lab produced stones that can be produced in unlimited quantities.
Some people will never understand why people buy an original work of art when they can buy a poster for next to nothing.
Earth mined gems are for those that do. Invest in quality.
