Stars emitted from large crystals!

Unheated star sapphire 15.54CT

When a star appears




Normal lighting


RECOMMEND POINT
Please take a look at the stars emitted from crystals over 15CT.
Star Sapphire 15.54CT, which you can tell at first glance that it is of high quality.

You may have seen 1CT or 2CT of Star Sapphire, but I think the number of people who have seen 10CT will decrease considerably.

Star sapphire is a sapphire that literally has a star.
This star sapphire is a gemstone that requires balance.

The reason is that

This is because inclusions are inevitably necessary as a star element for star sapphire.

This may be an unnecessary explanation, but star sapphire reflects light diffusely due to the inclusions inside the crystal, giving us a fascinating view of the star.

The more inclusions there are, the more opaque it becomes, but the star will clearly appear.
When the inclusions decrease, the star will be thin but clear and you will be able to see the beautiful appearance of the star sapphire.


Star sapphire has these contradictory dual characteristics, but I think the looseness you choose will vary greatly depending on which condition you place more emphasis on.

There are two points: get a star or get a clear score.

Now, this star sapphire is clear, but the star is clearly visible, making it a stone that maintains an extremely difficult balance.

Therefore, it can be said to be extremely rare.

Since it's Star Sapphire with 15 CTUP that you can't even choose in the story in the first place, the truth is that Zeitaku can't be chosen.

Loose back side
By the way, the explanation on the back is unnecessary for those who are jewelry connoisseurs.
The back side is usually not polished as polishing may change the way the stars appear.

It is extremely common to have uneven surfaces.
Therefore, star and cat's eye stones are evaluated only on the surface.


Size, transparency, color, star and
A stunning gem of premium quality.

The wonderful quality of natural unheated crystals.

It is not distributed in the market enough to choose,
This is a gem that is hard to find even if you look for it, so please take this opportunity to cherish this encounter.
