New entry in collection (ruby)

Rubeum · Nov 17, 2013

I did not know if share or not to share this photo, my poor and old Lumix FX12 doesn't capture well the red, turning it into improbable pink or purple. So below I put a picture of a different ruby, taken from the internet, which shows circa the true color.
It's a GIA cerified: 2.20 carat, natural Ruby, Red, Transparent, CMT Type I, not heated, not treated. I'm planning to ask for a SSEF certificate.
I was struck by a very rich red and a beautiful distribution of rutile, the light has a very velvety appearance.
P.S. can you recommend a good digital camera to photograph the gems?

Beautiful stone Rubeum!!! Any ideas how you will set it?

Gorgeous! I love rubies--they're one of my favorite gemstones. Also, I love velvety stones.

I have a velvety sapphire, and I love the soft glow of it.

Try taking a picture in "warm" light that brings out the red. There's info on it here under "Influence of lighting on color":

I know the effects of light sources on the gems. Here the problem is to capture the red by the digital camera, the sensors of red are in the minority compared to those of green and blue.

I'd like to mount it, but I have to work yet at the design of the structure

I find it easiest to take pictures of all gems outdoors, especially stones with fluorescence. I do not use any fancy equipment or accessories, either my cheap 10 year old point and shoot camera or my iPhone 4 (more often used). I hope SSEF's evaluation will match up with the GIA lab report.

The stone looks better to me on my work PC than my lappy at home, as I can see more pink and less orange.

Lovely stone, thanks for sharing.

With a normal digital camera, red is difficult to capture because only a quarter of the sensors of a Bayer filter are dedicated to red (Wiki pic):

In each case the stone is really equal to the example I posted below, also in the transparency. In the coming days I try to make some decent pictures, with a best source of light.

Regarding the mount. I have some not mounted diamond (photo by 9900 Blackberry

) with different cuts, except the two Asscher on the sides. Everyone are D color (GIA cert), except the central that is a Fancy Intense Pink (GIA cert), but I do not like to put the rose with red.
I also have an envelope with 100 diamonds (D / E / F color) with a diameter of 2 mm each (0.035 ct stone).
The stones are not lacking. But maybe I would love to do a mount in a medieval or renaissance style.

P.S. I prefer SSEF and AGL certificate because they give you also a technical idea of the color saturation. In this case I would say that could be medium to strong... but GIA is a good CS cert. Professional, at least.
