But minerals are generally more expensive than gems, such as 0.0.
And it's random, not necessarily the gem you need, so you see that the auction house's gem is cheaper than Minmetals, so you buy it and upgrade it.
Attached is the quantitative probability of the mineral processing results of precious stones that can be obtained by blasting [copper mine] at this time. Copper slag 1 100.0% malachite 1 50.0% tiger eye stone 1 50.0% shadow stone 1 10.0% skill point =50. We can start blasting [tin mine]. The quantitative probability of mineral processing results is 1 100.0% green agate 1-2 35.0% moonstone 1-2 35.0% shadow stone 1-2 35.0% topaz13.
Quantitative probability of blasting beneficiation results [iron ore] iron slag 1 100.0% topaz 1-2 30.0% jadeite 1-2 30.0% moonstone 1-2 30.0% turquoise/kloc-2.
Quantitative probability of blasting beneficiation results [secret silver mine] secret silver slag 1 100.0% turquoise 1-2 30.0% ruby 1-2 30.0% topaz 1-2 30.0% giant emerald/kloc.
At the same time, the quantitative probability of the mineral processing results of [silver mine] is 1 100.0% ruby 1-2 30.0% giant emerald 1-2 15.0% sapphire1-2/. +0-2 15.0% gold Delaney stone 1 2.0% abyss olivine 1 2.0% flame plagioclase 1 2.0% shadow Delaney stone 1 2.0% blue moonstone/kloc-0.
Of course, with the increase of points, gems may become very expensive. At this time, if the mine is cheap, you can still choose to blast the mine to upgrade the gem. It depends on the price of gems and minerals on your server. I hope my answer is helpful to you.
