I am looking to purchase a stone to go in a gold necklace for my girlfriend.
I am not looking for the average. I am looking for a stone guaranteed to increase in value.
I am not looking at fancy diamonds because i am thinking of getting her a pink diamond as an engagement ring when we get there…

I have narrowed it down to

Spinel Information
Spinel is a special gemstone in many ways. For centuries it was mistaken for ruby and gained undeserved fame. Today fine red spinel is more rare than ruby but less valuable.
Although commonly thought of as red, spinel can be found in a range of beautiful pastel shades.
Of particular interest is a vivid hot pink with a tinge of orange that is mined in Burma that is one of the most spectacular gemstone colors in any gem species. Spinel also comes in beautiful blues, which are sometimes called cobalt spinel, but these are rare.
Large stones (2.5cts-3+cts) are very rare and star spinels are very rare.

Sapphire Information
Sapphire is very rarely found, making it much rarer then the diamond, hence the market price for this stone is on the rise.
It’s safe to invest in a untreated sapphire as there sure to be value add to this stone.
There is a difference in price among sapphires depending on the colour quality, whether its treated or untreated, carat size, shine and brilliance. Though the most popular color is blue and pink the choice of colour is a personal choice and with sapphire you can find them in many colours.
Almost all (99%) Sapphire on the market is routinely treated with ‘heat’ to enhance and stabilize the colour. The typical heat treatment process is a permanent process and it does not normally adversely affect the performance, and durability of the gem, but in recent years demand for natural non-heated non-treated top quality Sapphire has caused these gems to command a somewhat higher premium, depending on the gem.
For those who prefer a pristine gemstone that has not been “enhanced”, there is an ever-decreasing supply of untreated gems.
Untreated gems are rare and likely to become more treasured for the rarity that they represent.

Ruby Information
Rubies are rare to begin with, and large, flawless ones are even more valuable than the very best diamonds.
Since rubies are a Clarity Category 3 gemstone, they invariably carry some inclusions, or other materials caught inside the gemstone as the ruby formed around them. A ruby without any inclusions would be priceless. A ruby with only microscopic inclusions is very rare and valuable.
Rubies are not generally very large, so their value increases with their weight. A ruby larger than 3 carats is very rare, and the 27.37 carat stone auctioned by Sotheby’s in 1999 is probably the only one of such size discovered to date. The larger the ruby, the more rare it is.

There are three types of ruby treatments available in the jewellery market:

Untreated
In the jewelry industry, it is assumed that rubies have been heat treated unless otherwise specified. These untreated stones are rarely encountered as only a handful of rubies in the world are untreated.
Large, clear rubies of good color that are untreated command extremely high prices and can only be found in the most expensive jewelry stores. When you see this word in a jewelry description, you can know that you’re seeing something rare (depending on the stone). If you see an “untreated” ruby for sale, it will be extremely valuable and expensive. Untreated rubies are almost always very included (unless they are in museums or with 6 digit price tags).
Colour is a ruby’s most important feature. Its transparency is only of secondary importance. An untreated ruby is very rare, and an untreated stone with only minimal inclusions is more remarkable yet.
Top quality untreated rubies are so rare even the world’s top gem dealers must incessantly comb estate sales and auctions to find them. Sizes above 3 carats are particularly rare. Almost all rubies are treated because most have inclusions. Treating the blemishes allows supply to keep up with demand. As a result, untreated rubies are usually museum-quality. Top dealers search for them, but few are available.

Conventional Heat Treatment and Fissure Filling or Glass Filling are the other ruby treatments,

I am out of room…

So hopefully you can help me narrow it down…
