Aquamarines of the AGrade quality as shown above are costly, simply because the increasing world-wide demand for this kind of high sea-blue brightness is not matched by an increasing supply of this high quality.
This high sea-blue bright Aquamarine colour is quite noticeable worn on the ear, for it simply stands out, bright, even when relatively small as in these well-matched 3mm cut rounds.
In the last 18 months ( this written end 2022 ), the price per carat of this quality natural Aquamarine has risen over 40%, and it will not become less expensive.
