When it comes to gemstone shapes, round gems are the most popular and versatile. Unlike oval gems, round gemstones are not cut to maximize carat weight, so more skill is often required by the cutter to bring out the color and brilliance in a gem. Many people confuse shape with gemstone cut, which isn't all that surprising. Looking at our selection of round-shaped gemstones, you'll notice a number of different round-cut stones; some are cut en cabochon, with no facets at all, while others are faceted in the traditional way, either with step-cut faceting or with more angular 'brilliant-cut' faceting. Other round gems may be given an unusual or mixed gem cut, such as concave-style cut, checkerboard cuts, or Portuguese-style cuts. Round rose-cut gems and round buff-top gems can also be found. Thus, it is easy to see why shape and cut are often confused, because there is one shape (round) with multiple cutting styles. Although many describe their gemstones using terms like 'round-cut', it isn't always the best description since there are many cutting styles; technically gems should be described as 'round Portuguese-cut', 'round step-cut', or 'round cabochon' for example.

The meaning of shape should be fairly obvious, which is the face-up outline of the stone, whether it is round, oval, square, rectangular, pear, marquise or trillion. Round gemstones should be symmetrical with a perfectly circular outline. However, in practice, a good percentage of gemstones are native-cut without the use of precision lasers and other advanced lapidary tools, so many round gems are not actually perfect circles and are rather better described as being near-round. This is why you may find that many still use three measurements for round gems. Most gemstone dealers will use only one diameter measurement and the depth (in millimeters), but to be more accurate, some dealers may advertise their items using the two diameter measurements, with one measurement at its minimum and another at its maximum, followed by the depth in millimeters. This type of measuring is more often used for diamonds rather than colored stones.

I had a great time searching all the lovely stones. This is my first precious loose stone purchase for my own work. I chose sapphire, and found some lovely briolettes. I wanted 3, but this set of 4 was perfect. Everything was quick and easy, and I'm excited.

I love the clear description of the certification options. It's very rare to see a gem site that offers a deep explanation of each institution that would certify the stone(s).

The website is user friendly, has excellent selection. I've always found what I was looking for with Gem Select. When others don't have it they do. And most important, they have a way for you to pay without using PayPal. I cannot use PayPal they closed my account because of no cell phone.

Purchasing from Gem Select was a pleasant and easy experience. The photos of the stones I was interested in were an accurate depiction of the stones I received. Ordering was easy and the items arrived within a week. Over all it was a very positive experience.

Very large selection of items and we used the stones to have several pieces of jewelry made for us.

over the experience was similar to other sites i have used. The only real note I have is the checkout experience was tedious and discriminatory, i wouldn't accept visa gift cards, which not only have guaranteed funds but help protect from misuse of personal information, but would not accept my visa b/c it is a prepaid card. I don't have bank account and I have been using the prepaid card for years without issue so this was disappointing to me. I feel safer using reputable gem sites rather than amazon or ebay (I have been sold fake gems with fake certs on both), but not being able to use my own valid legitimate funds and having to find a friend to buy for me b/c I use a non-bank card like 40% of the country is insulting.

I have used this site for sseveral years now. All has been great. I started collection gems from GemSelect for years and wanted to collect at least one of most stones. I loved Safers because the mols is a 9 + and they come in every color. This is the best place to buy gems for the assortment and price. Great place to learn about gems too. Sometimes the shipping is a little on the long side. But I would give them a 9.9 out of 10 !!
