Spinel is a very underrated stone with its own unique beauty. Seeing the Spinel in its Marble matrix was a special treat. Thank you for sharing.

So the other day I had the realization of why we call a rhombus a diamond. An octahedral crystal looks like a rhombus and diamonds form octahedral crystals, so uncut diamonds looks like rhombuses.

Rebecca is so knowledgable & so thorough, patient and clear in explanations. J'adore you Rebecca Thank you!!! <3

I've got a spinel collection. Most of them are red but I also have a fair amount of blue and bluish grey. 22 red spinels and 17 blue. I also have pink, purple and orange ones. What still evades me are the green and yellow ones though.

The reason I love gemstones and crystals because it's the impurities the imperfections is what makes them beautiful challenge for everyone look at people like you would a gemstone see there impurities not as inspections but what makes me beautiful

Spinel is my favorite gemstone. It has a purity of color thanks to its SR optic character, and in the right lighting conditions has a good level of dispersion. I advise those who enjoy spinel to purchase it now because it is going up in price steadily. It can't hide its identity any longer. Something else that I point out is that as long as there is magnesium in the presence of aluminum oxide then spinel will continue to grow/form. However, once the magnesium is used up then sapphire and ruby kick in from the remaining aluminum oxide. Thanks for another first class gemstone video.

The classic pink Spinel crystals are so gorgeous but I would have to say in cut form, that dark and deep navy blue has to be my favorite!

Spinel has always been an underrated🥺 stone from the others especially rudys until now.💁‍♀️😏 This gemstone is so beautiful and to know how it was created is amazing.😍❤🌟 There's so many colors🌈💎 of it, I never knew there was black spinel before.🖤 It's hard to choose, I like all of them.🥰 I hope you do another video about more underrated gemstones. Thanks for sharing to us and see you later.👩‍🏫💎

Natures secret: If you leave Spinel in a garden for 6000 years, Spinel will try to poison the earth.

I am a guy loving spinels.

Definitely the grey-blue versus the luminous cobalt blues, but for me the grey-blue on a vintage silver ring would be simply perfect.

One of my favourite unsung heroes, love them from their story of formation to their use. Great introduction to this wonderful and durable gemstone 💎

I might like spinel a bit more than I've ever had before. Sweet!

grey 100% so classy, so clean

Spinels are, as a whole, a boxful of eye-chocolates; in fact, I ordered my first pair of those pretties! I have black spinel beads, too!🤩🤩🤩

Very nice gemstones. I have 2.2 cts. Top Red Spinel & 5.06 cts. Cobalt Blue Spinel.

Spinels of comparable color saturation and clarity are actually rarer than sapphires and rubies; I’ve seen some blue spinels (electric neon cobalt blue) go for around $20,000/ct for a clean, 2+ carat stone. I’ve yet to see a sapphire look like that color; almost like huauyne or afghanite but backlit.

I love purple-red and black spinel!!!

Wow I love the black spinel 😱😱😱

I am A lover of black spinel although I examples of most in gem form.
