Establish your budget
Diamonds are expensive. So, first of all you must explore your options. Establish your budget based on your income. It is always better to tell the jeweller about your budget, so that he offers you something within your range. If you have already done the homework, you wouldn’t be much confused at the counter.
Learn about diamonds
It is important to understand the four C's of diamonds, such as Carat, Colour, Clarity and Cut. By completely understanding these factors, you would feel more comfortable in making a decision.
Understand ring settings
A ring involves many things apart from the diamond. For instance, one must keep a close look at the band, accent stones, and the prongs.
Most diamond rings are set in gold, yellow or white. A few are also available in platinum. So, it is all up to you to decide which metal you want in your diamond ring. 18k is recommended if you are choosing gold.
Design your ring
No matter how expensive the diamond is, your ring will look cheap if the design is not beautiful. Jewellers display rings without the diamond inside, which means you need to select both the ring and the diamond separately.
It entirely depends on your choice, when it comes to choosing the design. Ask for help, and inquire about the latest styles. It is always better to research online and select a design before going to the shop.
Her ring size
Diamonds rings are very expensive, and cannot be altered easily. Therefore, take exact size of your lady before going to the jeweller. If you have never bought a ring before and want to surprise her, secretly take the ring she mostly wears and press it into a soap to trace the outlines.
