Sky blue topaz and aquamarine look similar, both blue, transparent, and crystal clear. And because quality aquamarines are much more expensive than topazes, there are many unscrupulous merchants who use blue topazes to pass themselves off as aquamarines for sale. How to distinguish between genuine aquamarine and topaz? Their differences have already been listed as follows.
Differences between the two gemstones
Size: Generally speaking topaz can be very large carats, while aquamarine is a little more difficult. So when you see a large carat of aquamarine, it is better to have the certificate tested.
Colour: the aquamarine we normally see is lighter in color, whereas the color of topaz is relatively dark.
Weight: Topaz has a higher density and feels very dense in the hand. If two strands of aquamarine and topaz bracelets are of the same size, the difference in weight will be obvious.
Purity: The purity of topaz is higher than that of aquamarine, which often has flocculent objects in it.
Cost: An aquamarine is much more expensive than a blue topaz. This is because a blue topaz is often created by dying a white topaz blue using radiation and high heat. On the other hand, aquamarines are naturally occurring, making them far rarer and more valuable.
Hardness & Durability: When considering a gemstone's resistance to scratches and abrasions, hardness is a key factor. The blue topaz outranks aquamarine, which rates at 7.5-8 on the Mohs scale, with a hardness of 8.
How to Identify the Two Gemstones?
Due to their striking similarities in appearance, it is difficult for the naked eye to distinguish between blue topaz and aquamarine, which is unfortunate for the customers and advantageous for certain fraudulent dealers.
What therefore should you do while purchasing an aquamarine? When browsing blue diamonds, exercise additional caution to prevent fraud! The price differences between an aquamarine and a blue topaz are really noticeable, so you definitely don't want to spend the same amount on both.
Looking at an aquamarine stone's hue is one of the greatest ways to determine whether it is genuine. The color of a genuine, natural aquamarine stone will be a light blue resembling the ocean.
Which Gemstone You Should Choose?
Nothing, not even a blue sapphire, can come close to a natural aquamarine for value for money when it comes to blue gemstones. However, blue topaz is a lovely substitute if you're searching for something more reasonably priced.
