Hope all is well with you and your family!
I have a jadeite pendant in my collection and it’s about 21mms. Can you help me to determine how many carats it is and what do you think of the stone concerning its
I appreciate your help in this matter.
Thank you so much!
Your green stone is set in a gold clasp and the weight of the stone cannot be determined. Even if it is a loose jade, one cannot determine the weight of the stone even by knowing the full dimension of the jade. We have to use a gem weighing scale.
For Round Brilliant and Baguette Diamond, the approximate weight can be determined by using a 4 disc pocket gauge as shown in the picture below. Diamonds are almost cut to exact standard based on their gemological properties. Hence, when you place the gauge over a Round Brilliant Diamond you can get a good approximation of the weight of the stone. Or if you know the diameter of a Round Diamond you can check up the weight on the internet, for example, a 1 carat round diamond has a diameter of approximately 6.4 to 6.5mm.
It is almost impossible to determine the authenticity of the jade by looking at an image. One has to sight the stone, feel it and see the texture or carry out some gemological tests on the stone.
The texture of the stone is identical to that of a jadeite jade as seen in the picture. The hue, tone and saturation of the jade are quite excellent. The color is also evenly distributed with no patches of cloudy white. If it is a jadeite jade and is natural then this is a very good stone, though I can’t really put a value to it.
I hope the above helps.
