Specs on an Asha or Moissanite… how?

@highschoolhoneys:  Moissanite has different enhancements. Amora-enhanced was supposed to be an H-colour, and FB is supposed to be one step below, but less warm than regular unenhanced moissy. Also, moissanite comes with a grading certificate that gives you the dimensions of the stone and the cut. I think mine was a “good” cut. 

Asha stones tend to come in two colours (D or H?), and you can choose which one you order based on the look you’re going for.

Just because they’re lab-grown does not automatically make them absolutely flawless. The Amora Gem comes in an Internally Flawless clarity that you must pay a premium for.

@highschoolhoneys:  yeah, I’m sure there is. I can’t really speak to that since I only know what I’ve learned about on the Bee, but hopefully someone more knowledgeable will come along with better info!

@highschoolhoneys:  ashas come in different colors, F/G, H, I, fancy yellow and fancy pink. Some people prefer more warmth in their stones, and ashas not being blazing white D’s allows them to be less obvious as simulants.  

 Lab created stones don’t always come out identical, or perfect. If you look at lab created and cultured gemstones ( such ad emeralds, rubies and sappbires) there is quite a bit of variation in color and clarity. Also, lab created diamonds come in various colors and clarity grades.

If gemstones are grown in labs in conditions that mimic nature, i.e., not always perfect, then the resulting crystals will have variations in them when it comes to color and clarity, resulting in the lab-grown versions being unique. Now, some crystals and gems are much easier to grow with some methods over others. One method may yield crystals of uniform color and flawless clarity, while another will result in each gemstone cut from the rough being unique. 

 

For simulants like CZ, the process is pretty easy for growing the crystals and give fairly uniform results.

 

Moissanite is much easier to grow than the Amora Gem, (they need different environments in order to obtain the different crystal structures), but each batch of rough will be *slightly* different from another, so while the individual stones can be decently uniform, the slight variations still result in a unique stone. I believe the “base” clarity for both moissanite and amora gem is “VS”, with the AG varrying anywhere from IF to SI as of now.

 

Now, lab grown diamonds are notoriously difficult to grow, with yellow diamonds being the easist, white being much more difficult. If the technology to grow large, colorless, flawless diamonds reliably was around, I’m sure many of us would be rocking them!

 

Both Gemesis and D.NEA Diamonds offer lab grown diamonds, and the web sites are a lot of fun to check out, I plan on purchasing a lab grown blue diamond for a pendant. 😀

Edit: As for stats, the color of sims, diamonds, and moissy can be graded on the D-Z scale, clarity can be graded the same, and whether hand cut or by machine, each stone will still have its own unique measurements, even if there are a significant number that are quite similar. So, I own a J colored 7.73×7.68mm Amora-ized OEC moissanite with VS clarity.

@highschoolhoneys:   No surprise people buy simulants for their similarity to diamonds at a much lower cost. Thus diamond simulants are marketed by trying to equate them to diamonds. To that end, moissy  and cz are measured in diamond equivalency weights and given analagous diamond grades for color and sometimes clarity despite that both are manufactured in a factory under controlled circumstances. That being said even chemistry has it’s imperfections and sometimes the manufacturing process leaves marks or less than ideal color in the moissanite. Grading is a way to measure that. The diamond scale is familiar to many people and equates the sim to a diamond.

@gemgirl6:  Why do you insist on being rude by calling Asha cz when you could just say Asha?

 

@highschoolhoneys:  Asha’s come in a few different colors.  Right now it’s F/G, H, and I.  But I believe before they use to offer E.  Anyway since btd.com is focusing on the Amora Gem they won’t really continue making a lot of them.  As for the Amora Gem it comes in D through G in color and IF to S1 for clarity.

I didn’t say anything about Asha cz in this thread! But I probably have somewhere else but WTH, its “rude” now to describe what something is??

sheesh, defensive much?Undecided

@gemgirl6:  It is a thread about asha and moissy.  Asha has a cz core but is not plain cz.  I’m not defensive just honest and to the point.  Try to start 2014 on a positive footing IRL and here in the hive by trying to be nice every once in awhile.

@highschoolhoneys:  To my knowledge although moissy crystals are grown in a lab, the crystals still need to be cut/faceted by hand. That’s why there is a lot of variation in cuts, especially like the OEC. They grow the crystal “rough” in batches then cut stones from various roughs. Depending on the growing conditions, some turn out better than others. The stones with the best color and cut are deemed “Forever Brilliant” now and the rest are sold as classic moissanite. BetterThanDiamond makes the “Amora Gem” moissanite and they have an “independent” person grade the color of the stone. There is a different growing process that is supposed to make the lattice structure of the crystals tighter, lowering the band gap, and creating more colorless stones.
