Under normal lighting

RECOMMENDED POINTS
See the stars shining from crystals over 15 carats.

A 15.54ct star sapphire that you can tell is of high quality at a glance.

Have you ever seen a star sapphire of about 1 or 2 carats?
I think there are some who have seen it, but when it comes to 10CT, the number of people who have seen it is likely to decrease significantly.

Star sapphire is literally a sapphire with stars coming out of it.
This star sapphire is a gemstone where balance is very important.

The reasons for this are as follows:

Inclusions are the factors that create the stars in star sapphires.
Because it will inevitably be necessary.

This may be unnecessary explanation, but Star Sapphire
Due to inclusions within the crystal
It scatters light and makes the star's appearance captivating to us.

As the number of inclusions increases, the stone becomes opaque, but the star appears clearly.
With fewer inclusions, the star will be faint but clear.
You will be able to see the beautiful appearance of star sapphire.

Star sapphire has these contradictory dualities.
Depends on which condition you place more importance on
I think the loose stone you choose will make a big difference.

The two things are: get stars or get clarity.

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

Therefore, it can be said to be very rare.

To begin with, it's a 15CTUP star sapphire that you can't even choose.
The truth is, we can't afford to be extravagant.

Loose back

In addition, there is an explanation on the back that is unnecessary for those who are knowledgeable about jewelry.
The back side is polished to reveal the star.
Polishing is not usually done as this may change.
It is very common for there to be bumps and dents.
For this reason, star and cat's eye stones are evaluated only on their surfaces.

Size, transparency, color, stars and
A stunning gemstone of premium quality.

The stunning quality of natural, unheated crystals.

There are not enough varieties in the market to choose from,
It is not a gem that you can easily find, so
Please take this opportunity to cherish this encounter.
