A diamond isn’t just a women’s best friend, but also holds a lot of worth as most natural diamonds have ages between 1 billion and 3.5 billion years. 🪨

To determine their quality, diamonds are graded using the 4C's system: carat weight, color, clarity, and cut. 💍

Many people expect a diamond to be unbreakable.

This is not true.

A diamond's crystal structure has ‘hard’ and ‘soft’ directions. A blow of sufficient force, in an exact direction, can crack, chip, split or even shatter a diamond.🔍💎🔬

Poised between lush blue, vibrant violet, and rich purple, exotic tanzanite is found in only one place on earth, near majestic Mount Kilimanjaro! 🏔

Found in 1967 by @tiffanyandco, tanzanite is a relatively new stone compared to other precious gemstones that have been discovered for thousands of years... 🕰

When a new, previously unknown gemstone enters the market, every person who sells and buys must be educated before transactions can occur.

Tiffany & Co. prepared educational materials that would make consumers aware of the gem, and they prepared materials to help jewelers understand it, market it, and explain its characteristics to their customers. 🏜📘

The size of a tanzanite gem influences its color. 🪨

If you have two stones of equal saturation, the larger stone will have a richer apparent color - because the distance that light travels through the stone influences its perceived color!

Today, nearly all of the gems being sold as "tanzanite" have a blue color that has been produced or enhanced by heating.

Ruby is the red variety of the mineral corundum, one of the hardest minerals on Earth. 🪨

Corundum is the mineral form of alumina, which crystallizes in the hexagonal system.

The red color of ruby results from a small admixture of chromic oxide.

Only red corundum is entitled to be called ruby, all other colors being classified as sapphires. ❤️💙

The most prized tint is blood red or crimson known in the trade as 'pigeon's blood' red. 🐦🟥

Emerald is one of the most fascinating and beautiful gemstones that has been one of the world's most popular green gemstones for over 5000 years... 💎

Emerald is a precious gemstone and a variety of the mineral beryl colored green by trace amounts of chromium and sometimes vanadium. 🪨💚

Beryl has a hardness of 7.5–8 on the Mohs scale.

The most desirable color is slightly bluish-green in a medium-dark tone with strong to vivid saturation. 💙💚💍

Clarity is important, but inclusions are tolerated more in this variety than virtually any other gem. 🔬

Sapphires are one of the hardest stones on the planet; only diamonds surpass them in hardness!🔨🪨

Sapphire is also a variety of the mineral Corundum and represents all the colors except red Corundum (which is Ruby).

Its physical and chemical properties are virtually similar to the properties of Ruby. 💙❤️

The word 'Sapphire' in its plain context refers only to blue Sapphire unless a prefix color is specified.💎

Sapphire is the most precious blue gemstone.💍

It is a most desirable gem due to its color, hardness, durability, and luster.✨✨
