Hello, nice color ; the star is a bit weak for my taste. On your pictures one of the branches seems to be utterly missing.
It is very difficult to combine a saturated color, a nice translucency and a well defined star !
Especially on Burma stones who are usually less rich in "silk" than stones from Sri Lanka, for instance.

I think that it's a great star sapphire. The missing leg seems to be caused by a tree blocking sunlight in that area of the stone. I would suggest shining a small flashlight on the stone when trying to show the star to best effect. Could you a take a picture of that stone from the side?

of course its not accurate to judge from a picture, specially for Star Corundum.
IMHO the color is Fine & even body-color, i cant tell about transparency but it seems to be semi-transparent to translucent.
the cut seems to be symmetrical, as for star i see not uniform & Incomplete rays , again i can not tell if its well centered or not.

any way its an attractive Ring :wink:

personally, I like this gem a lot! the color, translucency, and the star effect are good from the picture. it is something to treasure. not so easy to get a burmese specimen of this size and color without much cracks.

cheers.

Pretty cab. Unfortunately, U.S. law prevents U.S. entities from importing any products from Myanmar.

The only gems banned are rubies and jade.
Every other gem, including sapphire is fine.
It's confusing.

It should also be mentioned that the poster in question lives in Madrid, Spain, not the U.S., so what's the point?

It's a lovely gem, with fine color and exceptional translucence, which is a big plus in asteriated corundums. A better image would help in judging the star but from what I can see it seems quite sharp and prominent.

Good morning and thank You All.
Your help is appreciated and always keep learning!
I enclose some more pictures with flashlight!!!
All your comments are valuable to me.
I've been offered another cab, this Ceylon Star Sapphire, transparency is great, almost unbelievable and the star appears and travels exceptionally and bigger than 10 cts. Do you believe are good pieces to collect?
Wishing ALL a nice Monday and prospers new Week!

I've been reading and I found the following paragraph:
"Finally, like ruby, when some rutile-filled stones are cut cabochon they produce a six-sided star. Regretfully, because the Thai cookers have discovered how to remove the rutile by heating these gems, they are becoming very rare. Also, in the 1940s, Linde, a division of Union Carbide, began manufacturing synthetic star sapphires. Of course the synthetic star's legs were perfect, and consumers began demanding the same from the natural gems. This is really too much to ask from a natural gem. Nevertheless, if you are interested in collecting natural star sapphires, here are some tips: The quality of the star is everything. The star is more important than the color. Grayish sapphires tend to have better stars than the top blues. Gray stones tend to be better cut than the blues. The blues tend to have sagging bellies, while the grays are flatter. This is because the blues are more translucent, and cutters must keep more of the original rough to retain a star. Therefore to collect fine blues, expect to pay for extra weight. However, on the positive side, the consolation is that blues with fine stars are rare, and sought after by collectors worldwide. If one or two of the legs of a star are missing in a 10 carat blue, expect to pay $3000 per carat. If the star is perfect, double this price-if you can find one. Prices ease a little at 5 carats or less. For collectors on a budget, you can buy light blue or gray stars for 1/10 of these prices"
