💎 Diamonds & Quality
Are your diamonds real?
Yes, all our diamonds are 100% real, genuine diamonds. We offer both natural diamonds and lab-grown diamonds, clearly labeled on each product. Every diamond over 0.5 carats comes with a certificate of authenticity from GIA, IGI, or another reputable gemological laboratory.
What's the difference between lab-grown and natural diamonds?
Lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. The only difference is their origin:
- Natural diamonds formed underground over billions of years
- Lab-grown diamonds are created in controlled environments in weeks
Lab-grown diamonds typically cost 50-70% less than natural diamonds of equivalent quality, making them an excellent value choice.
What do the 4Cs mean?
The 4Cs are the universal standard for evaluating diamond quality:
- Cut: How well the diamond reflects light (most important for sparkle)
- Color: How colorless the diamond is (D is best, Z has visible color)
- Clarity: How free of inclusions and blemishes
- Carat: The weight/size of the diamond
What type of gold do you use?
We primarily use 14K gold, which offers the ideal balance of durability and purity for everyday wear. We offer:
- 14K White Gold: Classic, silvery appearance
- 14K Yellow Gold: Warm, traditional gold color
- 14K Rose Gold: Romantic, pinkish hue
Select styles are also available in 10K gold or 18K gold.

There are several ways to find your ring size:
- Use an existing ring: Measure the inner diameter and compare to a size chart
- Visit a jeweler: Get professionally sized (free at most jewelry stores)
- Use our printable ring sizer: Available on our Ring Size Guide page
Do you offer free ring resizing?
Yes! We offer one free ring resizing within 30 days of purchase for most ring styles. Simply contact us to arrange the resizing. Some intricate designs (eternity bands, tension settings) may have limitations on resizing.
