Consider the color of the gemstone.

One of the best parts about buying loose gems is you can choose any stone you desire to create a truly unique piece. The traditional color for a Valentine's Day gift will most likely be red. Red indeed is the color of passion, confidence, and love. But when it comes to present giving it is the thought that counts and buying what you want for your loved one is what's most important.

At GemSelect we have beautiful gems of all colors blue, purple, yellow, orange, green, pink, and red.

Think of the colors your partner would like and would find unique or the colors that you believe will compliment them. If you want to choose red, there are stunning shades from which to select. With so many different gemstone colors and intensities that we suggest shopping for stones with the consideration above, then looking for a gem or pair that speaks to you.

The thought is what counts but don't over think it because any quality gemstone is sure to dazzle your Valentine.

Clarity of gemstones how it varies and what to look for

Don't be frightened by the word clarity because in colored gems it is much less expensive than in the diamond world. Many colored gemstones have great clarity that is specific to their gem types like zircon, aquamarine, citrine, and amethyst; contradictory to the ease of finding clean gems in some types are the gem types where it is difficult to find eye clean pieces like certain types of Garnet Hessonite for one.

In gem types like Sapphire, Ruby, Tourmaline, and Tanzanite VS and above are a good indicator that you are getting a quality stone, but there are also some great gems that are a little lower like VS-SI especially in Ruby. Some rare and beautiful gems may have inclusions that do not detract from the value so make sure not to focus too much on this. Just because a gemstone isn't internally flawless doesn't mean it is a bad choice.

Check out our gemstone clarity chart below to familiarize yourself with the terms, and if you have any questions about gems you would like us to inspect let us know at

  • IF Clarity - Loupe clean - internally flawless; free of inclusions.
  • VVS Clarity - Almost loupe clean - very, very slight inclusions; inclusions barely seen under 10x magnification.
  • VS Clarity - Usually Eye clean - very slight inclusions; slight inclusions will be visible by the trained eye, or when viewed under 10x magnification.
  • SI Clarity - Slightly included - Inclusions are noticeable and can be seen with the naked eye.
  • I1 Clarity - Included - inclusions are obvious and can be seen with the naked eye.

Common gemstone sizes for jewelry designs

At GemSelect we believe any size gemstone is a great gift and we are sure you Valentine will appreciate anything you choose; however, you may need a little more assistance than reassurance. Here are some tips to simplifying the decision for you.

GemSelect suggests thinking of size in simple terms first. How big of a gemstone do you want to give this year? If you are looking for something large or small and don't know what size to buy reference our list below for sizes of common designs like rings, earrings, and necklaces. Later we will give you details on gem types to make sure you get a piece that not only fits your size requirements but your budget as well.

Rings - If you're looking for something big a gemstone in the 10mm - 13mm range ought to do it and if you're looking for something small you can easily mount a 3mm - 7mm stone into a ring and end up with a beautiful finished product.

Earrings - Common gemstone sizes for earrings are from 5 mm - 7mm on the smaller end and between 10 mm - 14 mm on the larger end. Either large or small earrings will look great once they are finished. If you're planning for earrings, remember to shop by pairs.

Pendants - Common gemstone sizes for pendants can range too so on the smaller end a 5mm - 7mm stone ought to do it and if you're thinking larger we suggest going anywhere from 10mm - 14mm range. Pendants are a great idea for gifts. Some of the upsides to making a pendant are the ability to utilize a large stone and your ability to buy some of the rarer pieces that are very uncommon to find in pairs.

Buying gemstones in calibrated sizes for convenience

TIP: If you want to get a finished piece of jewelry completed quickly buy a gemstone or pair that's in a calibrated size. Calibrated gems will be easier to mount because the calibrated millimeter sizes are used worldwide to standardize jewelry settings.

These earring mounts below come in a 9 x 7 mm standard size so making earrings out of the Tanzanite shown above is easy as one, two, three.

To tell if the stone or stones you are viewing are calibrated look to the detail page like the one shown above, where it says 'size' you will see the area that indicates 'calibrated' we have underlined it in red, so you will know precisely where to look. If the word calibrated appears next to the dimensions, your gem will be very easy to set into mounts like the ones pictured above.

What are some of the most popular Gemstones and their qualities?

The most spectacular gemstones are Sapphire, Ruby, Tanzanite, Spinel, Aquamarine, Zircon, Garnet, Topaz, and Amethyst. We will list some of the qualities of each gem type below in addition to a picture and link to our inventory.

Sapphire: Sapphire comes in all colors besides red which is reserved for ruby. It has exceptional brilliance, in other words, these gems sparkle and it's incredibly durable so it will last a lifetime. While blue is the most traditional color of Sapphire and very beautiful, we have gorgeous Sapphire in all colors of the rainbow. Sapphire is known to have some inclusions so as long as they are minimal, they do not take away from the value of the stone. Large sizes of Sapphire are an excellent choice for investments as they will increase in value especially the favorite colors.

Ruby: Ruby 'the king of precious stones' is in the same family as Sapphire. The largest and most obvious difference is the color of ruby, its red. This stone is the most valuable colored gemstone on the market so if you're looking for a piece that will show your love, devotion, and wealth shop ruby. Ruby like Sapphire is expected to have inclusions. Inclusions are one of the ways to tell a ruby apart from either a fake gem or a gem that's a different gem type.

As long as the inclusions aren't large or detracting from the brilliance of the stone, they will not reduce the value of the gem. Ruby can be expensive if you are shopping for a high-quality gemstone, but we guarantee your Valentine for life will remember the gift of ruby. Large high-quality pieces will hold and in time are guaranteed to increase in value.

How to turn your gems into jewelry - Mounting

So you have done it, you have spent the time and picked out an excellent gemstone or pair for the gift you will give this year. Now there is one last step making it into a wearable piece of jewelry. What is the trick how is this done? Well, it is much easier than you may think because any good jeweler will have settings or 'mounts' on hand for your newly purchased gem or gems, so long as you bought a calibrated size obtaining the mounting should be a breeze.

So here are some terms: semi-mounts and mounts and we will briefly describe the difference and how you can use them to create your jewelry.

For rings, earrings, and pendants semi mounts are great if you are looking to make a significant gift. The semi mount will already have diamonds set in a 'pave' and an opening where the stone or stones you purchased will go. Here are some examples of semi-mounts.

If you are looking for something a little less pricey, you can keep it simple and go with a traditional mount for a solitaire ring, a simple pendant, or a simple pair of earrings like studs. Your local jeweler will be able to show you several designs from which you can choose.

Both the mount and the semi mount are the same regarding how simple they are to set with a gemstone. The only difference is the semi mount is set with diamonds. By purchasing calibrated stones and choosing either of these options, you can sometimes have your piece completed in only one day. Remember that mounting will make your gems look much better so prepare yourself because we're sure the jewelry you create will look so spectacular that you and your Valentine will smile from ear to ear.
