Here is an interesting thought...
Numbers 15:37 The LORD said to Moses, 38 "Speak to the Israelites and say to them: 'Throughout the generations to come you are to make tassels on the corners of your garments, with a blue cord on each tassel. 39 You will have these tassels to look at and so you will remember all the commands of the LORD, that you may obey them and not prostitute yourselves by going after the lusts of your own hearts and eyes. 40 Then you will remember to obey all my commands and will be consecrated to your God.
Just as we are to have the Law in our mind and all the deeds of our bodies are to reflect the Law of God... So the tassels at the four corners of the garments are to help you remember. Blue.. like sapphire.. like the Blue Sapphire Stones of God's Law....to remind you of the Law of God.
I've always been under the impression that the techlet thread was to represent heaven, as from where we stand on earth, that is blue, which color I think changed from antediluvian times.
But comparing stones in the Bible to our current names has been an ongoing debate. I have some older books on gemstones and the folk lore attached is something.
I think an assumption was made that because of the tzitzit thread being of the techlet or blue, that the sapphire should also be blue. Now this could be the case but a deep blue sapphire stone in a thickness enough to support the general size of the tablets I would think would be too thick and dark to read through to the other side.
There is a White Sapphire stone though and it is heat treated to get the clearness and clarity like a diamond. And from what I've read there was plenty of heat on that mountain!
As you can see
from these two , they are practically as clear as diamonds and quite rare and expensive too.
Natural sapphires are found in Southeast Asia, the Indian subcontinent, parts of Africa,
the Middle East, and in the Western states of America.
They also come in other colors, blue, purple, yellow, brown, and an interesting bit, they also can have an unusual property that causes refraction of light and are referred to as Star Sapphires. I used to have one of these myself and depending on how you held it in the light you could see deep into it and it would reflect from within a star pattern, much like a star lens on a camera will reflect the sun into a star pattern. If this were on a clear stone or even a lighter blue with these properties this might explain how the words could be read from either side.
Say
like this one
Just some thoughts.
