4 Carat Sapphires
Buy gems by carat weight. Sapphire, with its Mohs hardness score of 9, second only to diamond, is one of the most valuable and wearable of all gemstones. Famed for its brilliance and rich blue color, sapphire actually occurs in a wide range of colors, including pink, yellow and green. 4-carat natural sapphire gemstones may be used in various jewelry designs, from engagement rings to earrings. Our 4-carat sapphire stones are available in various shapes, cuts and colors, such as blue, fancy pink, yellow, violet and white. Sapphire is every color of corundum except for red, which is ruby. The name corundum comes from the ancient Sanskrit "kuruvindam", while the name "sapphire" comes from the Persian word "safir". Sapphires are seen as the guardians of love. When given as a gift they enhance love and tune your spirits to one another. Also, sapphires have been used to banish envy and jealousy as well as promote fidelity in marriage. From this page, you can use our filters at the top or on the left-hand side to find sapphire gems by color, shape, cut and so on. For example, select 'gold' to see all of our golden yellow 4-carat sapphire gems. Select 'oval' to see all of our 4-carat oval sapphire gems. Also filter by single, pairs, lots, faceted gems or cabochons by using the check boxes at the top.

finally bought the last rock to complete my ring idea; needed another white one after giving the big diamond to my daughter. a diamond that size is out of my retired-school-teacher budget, so i bought a white zircon. went back to the same place that i got my loose sapphire-- great selection, good prices, good delivery!

I'm always real pleased with this website, I don't think there is much you could do to make it any better. I wish the shipping charges were lower, but it is understandable.

This is a site that sources valuable and genuine stones forms around the world, with and honest and descriptive sections, as well as specs, and the option to have the gemstone collection one might purchased—certified! Price ranges vary, but are always affordable and always worth it, whether it’s a gift, or for a personal business.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
