@MrsBlah:  well cut diamonds go dark under direct light.

My diamonds do the same thing!  Maybe they get in bad moods, lol.  πŸ˜‰  Seriously, nothing to worry about, really, it’s a good thing and very typical.

Yup, diamonds are refractive so light makes a big difference.  It needs “light” to reflect to sparkle. 

I would say that’s the issue.  But clarity can also play a big factor, but from what you describe it just seems you notice it in certain lighting so who cares.

You have nothing to worry about, PPs are right. Well cut diamonds sometimes go dark like that, especially under strong direct lighting.

Cut refers to the proportions/angles of the diamond. Better angles lead to more light being directed to your eye, which leads to more sparkles. If anything, be happy that you have that ‘problem’ πŸ™‚

Lol, oh ya what a problem to have.

As the other Bees have already answered your question… I offer up this tid-bit of good info as well

If you have a well cut diamond, and you cup one hand over the other, and leave an opening so you can see inside (so your top hand kind of looks like a backwards C… with your thumb forming the bottom) a well cut diamond will pick up on the light that is coming in from the side (thru the opening) and sparkle up top like all get out just the same.

Gotta love well-cut sparkly diamonds

I have an excellent cut diamond and it looks sparkly and brilliant in good lighting but in crappy lighting it looks dark and gray just like yours! I wondered why it did that too! I hate it sometimes bc I work in a restaurant with low/crappy lighting and you can’t see what a beautiful stone it is!!!

Agreed that excellent cut stones can go dark under very intense light like direct sunlight. I find that mine sometimes looks terrible in direct sunlight, but is spectacular if I move under a tree or if I backlight my hand by holding it against the sun. A well cut diamond will look great in MOST lighting, but direct sunlight and direct spotlights typically aren’t so great. Going dark is actually far better than your stone appearing opaque and white in the sun (“frozen spit”), which indicates poor clarity.

I’ve been wondering for months why my round brilliant center stone looks gray in direct sunlight. In diffused sunlight and indoor lighting, it sparkles all over. The diamond is GIA certified, excellent cut, D colored, VS2, and does not have flouresence. I would expect it to be bright and white in direct sunlight, so this has been bugging me.  I feel better reading this is normal with well cut diamonds and hope that’s true! πŸ™‚
