FAQs
💍 Is cushion cut good for engagement rings?
Yes, absolutely. Cushion cut diamonds are one of the most popular choices for engagement rings due to their soft, romantic appearance and vintage appeal. Their rounded corners and brilliant facets make them sparkle beautifully, and they suit a variety of settings—from classic solitaires to intricate halos. They’re also ideal for people who love a timeless yet distinctive look.
💎 What makes lab-grown diamonds affordable?
Lab-grown diamonds are 30–50% more affordable than mined diamonds because they don’t involve the costly and resource-heavy process of mining. They’re created in a controlled lab environment using advanced technology, which reduces overhead and environmental impact. Yet, they are physically, chemically, and optically identical to mined diamonds—making them a smart, ethical, and value-packed choice.
🔬 Are lab-grown cushion cut diamonds real diamonds?
Yes, lab-grown diamonds are 100% real diamonds. They are graded and certified by the same gemological institutes (like IGI or GIA) as mined diamonds. The only difference is their origin: lab-grown diamonds are created using clean energy and science rather than extracted from the Earth.

Engagement Ring FAQs
What is the averange cost of Engagement ring?
The average cost of an engagement ring is between $1,500 to $2,500. However, there is no set rule here. Most buyers make a realistic budget they can afford and stick to it (the old "rule" of spending three months salary is usually not followed). Dont be embarrassed to discuss it with a family member, a diamond expert, or a jeweler. Decide what is essential and how much you are comfortable spending before purchasing.
Should I get a ring with a Certified Diamond?
The answer is yes if you care about quality and want to buy confidently. Third-party certification labs like the IGI are independent and can accurately evaluate the diamond quality and authenticity with your purchase.
Should I get a natural diamond or a lab created diamond engagement ring?
There is no right or wrong choice between a natural diamond or a lab-created diamond for your engagement ring. Both are excellent choices, but if you are conscious of your budget, lab created diamonds are the more cost-effective choice, as they are 50% to 80% less expensive than natural diamonds.
Is there a difference between a wedding ring and an engagement ring?
An engagement ring is presented or given as part of the proposal. A wedding ring, usually without a central diamond or stone, is traditionally received when you exchange your vows during the wedding ceremony and wear them from then on.
Should I finance my ring?
It is always important to weigh your options and decide how to pay for your ring based on your given budget (most retailers also let you pay for an order with multiple payment options). With many financing options, like Affirm, Afterpay, Klarna or PayPal credit, you can buy her dream engagement ring on flexible terms without maxing out your credit.
How long does it take to complete an engagement ring?
Planning your proposal and allowing enough time to receive your ring is essential. The average lead time for engagement rings can vary between 2 to 4 weeks (some custom designs may take longer) based on the complexity of the ring.
What is the best engagement ring setting?
Finding the perfect setting for an engagement ring is a challenging task. An engagement ring setting physically holds the center stone of your choice securely, so it is best to choose a setting that will elevate the center stone and highlight its beauty even more. The most well-known setting is the prong setting, which is usually paired with round-shaped diamonds, and the halo ring setting is a popular choice for princess cut stones. Other settings are the bezel setting, channel setting, pavé setting, and cathedral setting.
Is it safe to shop for engagement rings online?
Yes, absolutely. Just make sure to shop at a reputable retailer. You can save up to 80% by buying engagement rings online compared to buying them from your local jeweler.
