FAQs

What is a 2.5 mm round sapphire?

A 2.5 mm round sapphire is a small, precisely cut gemstone with a round shape and a diameter of 2.5 mm. It is commonly used in fine jewelry, including rings, earrings, and bracelets. Sapphires in this size are available in various colors, such as blue sapphire, pink sapphire, yellow sapphire, white sapphire, and green sapphire.

Are 2.5 mm round sapphires natural or treated?

Sapphires can be either natural or treated. A natural 2.5 mm round sapphire is mined directly from the earth, while a heat-treated sapphire undergoes a process to enhance its color and clarity. Some options, like an untreated 2.5 mm round sapphire, remain completely natural without any enhancements.

What colors are available for 2.5 mm round sapphires?

There are many color variations, including blue sapphire, pink sapphire, yellow sapphire, white sapphire, and green sapphire. One of the rarest varieties is the round Padparadscha sapphire, which features a unique pink-orange hue.

How can I use a 2.5 mm sapphire in jewelry?

A 2.5 mm sapphire is perfect for various jewelry designs, including engagement rings, wedding bands, stud earrings, and bracelets. The round sapphire shape provides excellent brilliance and works well in solitaire and multi-stone settings.

What is the difference between a round sapphire and other shapes?

A round sapphire is cut to maximize sparkle and light reflection, making it a popular choice for fine jewelry. Other shapes, such as oval sapphire or cushion sapphire, offer different aesthetic appeals but may not reflect light as evenly as a round 2.5 mm sapphire.

How do I choose between a heat-treated and an untreated 2.5 mm sapphire?

A heat-treated sapphire has undergone a controlled heating process to improve its color and clarity, making it more vibrant and visually appealing. An untreated 2.5 mm round sapphire is completely natural, with its original characteristics preserved. The choice depends on personal preference and budget.

Is a 2.5 mm round sapphire durable?

Yes, sapphires are among the hardest gemstones, second only to diamonds. A 2.5 mm round sapphire is highly durable, making it suitable for everyday wear in rings, earrings, and bracelets without worrying about scratches or damage.

I found what I was looking for...had to look up millimeters to inches. It would be nice to see something, like a quarter, in the pix to show relative size. I plan on buy loose gemstones for every month in the calendar

I have been buying gems for several years off and on and love their selection and great low prices. I started out wanting to get an example of each type of gem but after looking at all the types of gems and reading about them I realize it is almost impossible for me to do. It took me years just to read about them all. Gem Select is the best gem site you can find. For information or to buy. Steve M.

I love Gem Select! When you order what you see is what you get. As soon as you make payment that particular gem is taken off the photo album. That way the one you select is a one of that kind.
