What is a YAG diamond?

Yttrium aluminum garnet (YAG) is a lab created gem first developed in the 1950’s. Its primary application was in optics and laser technology, but it turned out to be a convincing diamond simulant. Although YAG has garnet in its name, it is not related to garnet; it is an artificial gemstone with no natural counterpart.

What are plastic diamonds called?

Synthetic diamonds are also known as laboratory-grown diamonds, laboratory-created diamonds, cultured diamonds, or cultivated diamonds. They are real diamonds but not grown by Mother Nature.

What is strontium titanate gems?

Strontium Titanate is a synthetic gemstone, produced through the combination of two metals: strontium and titanium. It is synthesized through a process known as flame-fusion, where the two metals are heated with a brilliant, hot flame and treated with a mixture of chemicals to produce this marvelous gem.

What is quench crackling?

Quench crackled quartz – Natural colorless quartz can sometimes be subjected to thermal shock, known as “quench crackling.” The colorless material is first heated, and then subjected to quenching in a cold, liquid solution—such as water.

Who invented YAG?

Danièle Aron-Rosa (born 1934) is a French-Tunisian ophthalmologist and physician-scientist most known for developing the picosecond, ophthalmic Nd:YAG laser for eye surgeries. She has been called one of the two most respected laser pioneers in ophthalmology, alongside Franz Fankhauser.

Which two of these simulants are man made?

The most common diamond simulants are high-leaded glass (i.e., rhinestones) and cubic zirconia (CZ), both artificial materials. A number of other artificial materials, such as strontium titanate and synthetic rutile have been developed since the mid-1950s, but these are no longer in common use.

What is a YAG laser used for?

A: A YAG Laser Capsulotomy is a laser procedure where the eye(s) is dilated, giving the doctor a view of the protein buildup behind the implanted lens. The YAG laser clears protein film to restore vision.

When was YAG capsulotomy invented?

In November 1980, Fankhauser performed his first YAG capsulotomy. The procedure caught on quickly because the alternative was surgical dissection of the posterior capsule, which is a more inherently invasive procedure. With the older intraocular lenses, opacification rates could be as high as 50%.
