Where do these gemstones come from?

These gemstones come from all across the world from the thousands of mines present. They are mined and shipped to us where we process them into small manageable pieces for you to geek over!

What type of treatment is done on these?

They are heated and then a solution of borax is sprinkled on top to enhance its color. However this can be washed off with strong soap and lukewarm water. So if you want to marvel over the true color of these beauties go for it!

Description

The color of a blue sapphire is more important than its clarity. Sapphire is rarely completely clean and even very expensive stones can be slightly included. Subtle differences in color can make great variations in valuations of fine gemstones. Fine loose gemstone beads for jewelry making of good color and clarity are always rare and valuable. Highly saturated medium or medium dark blue tones are best, blue sapphires which are too dark or too light are worth considerably less.

Llego empapado en una substancia aceitosa, que me parece asquerosa. La piedra se veia feito quando la saque. Pero quando la lave y seque, pues si se ve mucho mejor, es zafiro, aun que es completamente diferente de foto, no hay ninguna comparacion. No hay ficha technica, solo escritto en bolsita que es zafiro. La entrega fue a tiempo aun que teniamos algunas problemas con seguimento pero todo quedo bien.
