Ruby Gems Heat Only
Rubies that have been enhanced by heat treatment only are becoming increasingly rare. Nowadays, nearly all of the rubies on the market are treated to enhance color and clarity, although untreated rubies can still be found. For the most part, heated rubies are very well-accepted by the general public, but nowadays, most rubies are enhanced through 'fracture-filling' technique. Although fracture-filled rubies are very affordable gems, sometimes offered for as little as $10-$20 USD per carat, many experts believe they should not be traded as 'ruby' since they are heavily enhanced. However, without this type of treatment being made available, most consumers would never be able to afford natural ruby. The filling of rubies has made them more affordable and readily attainable for anyone. The downside to filled rubies is that they are much more fragile than ruby which has been heat treated only.

For those who can afford natural rubies that are only enhanced through routine heat, then we definitely recommend buying non-fracture-filled rubies. Heat-only rubies are excellent investment gemstones as they tend to gain value over time. With ruby sources and production slowly depleting, it may be hard to find heat only rubies in the near future. Prices for fine quality natural red rubies can be very expensive, especially gemstones with top color, clarity and cut, but when buying from the source, you can save thousands of dollars versus paying full retail at your local shopping malls.

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
