The price of garnet depends on its quality, and the quality of garnet depends on four aspects:

Color, the same quality, wine red, orange red, rose red, rose purple prices from low to high;

Transparency, the less ice cotton, the more transparent, the higher the price, and the crystal clear glass has the best texture;

Ice crack, the less ice crack, the higher the value, and the top grade without ice crack;

Flaws, the fewer flaws, the higher the price, and the flawless product is perfect.

I have attached a picture here, with Brazil rose red on it and Mozambique wine red on the bottom.

Under the same quality, the bigger the beads, the darker the color and the higher the price. You didn't specify the size. If 30 pieces are a single circle, the estimated diameter is 5-6mm. If it is larger, please indicate the size.

It is recommended to start with the best, collectible, and the price of wine red is not very high. Collection-grade garnets cost 15-20 per gram, and the weight of each 6mm is less than 0.5g, which is almost 10 yuan.

The price of Brazilian rose purple is still very high. The price of Indian rose purple is much lower.

To sum up, is this expensive for you? If it is wine red, there is no ice crack, and the glass texture is crystal clear, 5-6mm or even larger, brand jewelry like Chow Tai Fook is not expensive in 300 yuan. If it is rose red and rose purple, 300 yuan can't buy good goods, and there should be ice cracks. For reference only.
