I have been a gemologist for decades and I am now retired and do this to raise funds for animal sanctuaries. My selling price is determined by what I had to pay, and it is always far below retail replacement value. The retail replacement figure is designed for bricks and mortar jewelers with high overheads. Many were purchased years ago.

For those that request it, I can provide my signed and sealed appraisal of $1050 retail replacement for an additional $5. My estimates are considered conservative, but I have no degrees. For those preferring an independent appraisal, I have many better gems listed here that have been appraised by master valuer Steven Knight GG,R.M.V. , CJA-CAP. Or I can send this opal to him for his appraisal for an additional $45.

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.
