Top Grade Gemstones

Our Top Grade gemstone product page is reserved for the best of the best, when only the finest quality gemstone will do.

Although we pride ourselves on our huge inventory of colored gemstones numbering in the tens of thousands it can take time to search through our stock for just the gemstone you need.

So we have gathered together the cream of the crop to make it easier for you to find them. To make the grade, a gemstone needs to possess one or two important factors, such as:

  • Color - only well saturated and rare colored stones make the grade.
  • Clarity - top grade gemstones tend to have exceptional clarity although emeralds and rubies have internal flaws which can add to their charm.
  • Carat - size is not everything but our Top Grade gemstones feature some impressive carat weights.
  • Cut - all Top Grade gemstones will have skillful cuts that show off the gemstone's best qualities.
  • Rarity - some gemstones only come around once in a while
  • Origins - certain locations have become synonymous with high quality gemstones - Mogok Rubies or Colombian Emeralds for example

Some examples of Top Grade gemstones we have featured in this section are:

  • Rare and exotic Grandidierite from Madagascar
  • Large, brilliant Zircons with a sparkle to beat a diamond
  • Stunning Deep Violet Blue Tanzanites
  • Very rare Imperial Topaz
  • Rose-pink Malaya Garnet
  • Champagne Diamonds
  • Enticing Emeralds

Of course at the apex of our Top Grade gemstones we have Asia's unsurpassed treasures, Rubies from Myanmar and Sapphires from Sri Lanka.

Remember, all the Top Grade gemstones you see on this page are available and ready to be shipped immediately. We never use stock or artificially enhanced photos - what you see is what will arrive at your door - guaranteed.

The Top Grade gemstones at GemSelect are all-natural gemstones - we do not buy or sell synthetic or lab-created gemstones.

Why buy Top Grade gemstones from GemSelect?

Our offices are located in Thailand which gives us access to the best quality gemstones from all parts of the world. It is estimated that 80% of the world's sapphires and rubies pass through our home town of Chanthaburi before reaching the jewelry stores of London, Paris, New York and other major cities.

We have traditional links stretching back centuries with neighboring ruby-rich Myanmar to the east and Cambodia, home to the best and most brilliant Zircons to the west. More recently, trade has developed with African gemstone powerhouses Mozambique, Tanzania and Madagascar which has lead to an amazing supply of top grade sapphires, aquamarines, garnets and tourmalines for us to choose from.

Why buy Top Grade Gemstones?

The most obvious reason to buy Top Grade gemstones is, of course, to make a beautiful item of jewelry. With the help of a jewelry maker or a jewelry designer you could create a one-of-a-kind piece that will be just a little bit more personal and meaningful. And, by the way, the money you save purchasing the loose gemstone from us will more than pay for the custom made jewelry.

The Top Grade gemstone could just become part of a very cherished collection of fine gemstones, kept in a display case or box.

Although Top Grade gemstones are not as easy or quick to exchange as gold or stocks they can be considered an investment when the very finest and rarest are bought.

What type of Gemstones are available as Top Grade Gemstones?

We have new supplies arriving everyday to replace purchased gemstones so the Top Grade gemstones are constantly being updated - check regularly to see what's new in stock.

What jewelry are Top Grade Gemstones suitable for?

All Top Grade gemstones would make exquisite jewelry items with rings or pendants being the obvious choice for most of the fine gemstones we have in stock.

Certain stones such as Apatite or Sphene may need protective setting when used as a ring because of their relative softness but skilled and imaginative designers will be able to create stunning jewelry pieces from each of these stones.

Are Top Grade Gemstones birthstones?

Yes, several gemstones typically featuring on our Top Grade product pages are birthstones - sapphires, emeralds, rubies, aquamarines, garnets, diamonds, tourmalines, tanzanites, opals, topaz and zircons for example.

The website is well organized and works fast forward and back. Plenty of filters. Each gem is described in detail and you receive the one pictured. Gem material info and sources available. I would like to see more specifics on sources besides country- at least region or state and in the US with Turquiose which mine. Thanks!
