Platinum Heart Shaped Solitaire Engagement Rings

Shape

Heart shaped diamonds are the most romantic of all the diamond shapes portraying the universal symbol of love. Due to their complex shape, they are also the hardest to cut. Make sure to look for a heart that is perfectly symmetrical on both sides with a length to width ratio of 1 or close to it.

Ring Style

Solitaire engagement rings are the most popular setting style at Ritani. A benefit to solitaire engagement rings is that they are lower maintenance - rings with diamonds in the band can sometimes fall out. They also tend to be less expensive than other setting styles since they feature a plain band. Additionally, solitaire engagement rings are easy to pair with any wedding ring. Round solitaire engagement rings are a classic choice. Oval solitaire engagement rings are growing in popularity and offer a distinctive look. Looking for a rose gold solitaire engagement ring or a yellow gold solitaire engagement ring? Save some money by going down lower on the diamond's color scale. The warm hues of these metals will complement the diamond well.

Metal

Platinum is a very popular choice for engagement rings. Platinum is a white metal that is also extremely durable. Because platinum is too soft in it's pure form to be used for jewelry, it is usually combined with a small percentage of other metal alloys such as cobalt, iridium, ruthenium, or palladium.

Lab Grown and Natural Diamonds

To complete your engagement ring, choose from our large selection of certified natural and lab grown diamonds. Whether you are looking for a 1 carat diamond or a 5 carat diamond, you are sure to find something that matches your expectations. Save 40% or more by choosing from our lab grown diamond collections.

All Ritani diamonds are certified by independent diamond grading laboratories. Our earth grown diamonds are certified by either the AGS or GIA – the two most respected independent grading labs in the world, while most of our lab grown diamonds are certified by IGI, the most respected independent lab diamond grading labaratory.

Frequently Asked Questions

  • How much should I spend for an engagement ring?
    arrow

    You may have heard the rule that you should spend 2 or 3 months of your income on your engagement ring, but this rule was just a marketing ploy created by De Beers. Your spend should be based on your budget and the type of engagement ring you are looking to buy.

  • What should I know before buying an engagement ring?
    arrow

    1. Budget - how much you are willing to spend on a ring
    2. Ring Style - are you looking for a classic ring or maybe a vintage ring?
    3. Metal - rings can be made of platinum or different types of gold
    4. Shape - the shape of the center diamond in your engagement ring
    5. 4 Cs - the color, clarity, cut and size of your diamond are important criteria in choosing your diamond

  • What is the average cost of an engagement ring?
    arrow

    For natural diamonds, the average cost is around $6,000 and the average carat weight is 1.25 carats. For lab grown diamonds, the average cost is $4,000 and the average carat weight is 2.5 carats.

  • What is a karat?
    arrow

    Since gold is too soft to be used in a ring, it is often mixed with other metals. The purity of gold is measured in karats. One karat is one part out of 24. Therefore, 24 karat gold is 100% gold (24/24), 18 karat is 75% gold (18/24), while 14 karat is about 58% gold (14/24).

  • Is platinum a good choice for an engagement ring?
    arrow

    Platinum is a very popular choice for engagement rings. It is the most durable out of the engagement ring metals and is naturally white so it does not require rhodium plating.

  • Is platinum more expensive than gold?
    arrow

    The price of precious metals are constantly fluctuating. However, platinum rings are usually made of 90-95% platinum, while gold rings are typically made of only 75% gold (for 18 karat gold) or less. Therefore, platinum rings are typically more expensive than gold rings.
