Grow a Carat

Grow-A-Carat Program

At McTamney’s, we believe each piece of diamond jewellery is as special and unique as the individual who wears it. We also recognize that as beautiful as a piece of jewellery may be, you may wish to increase the size or upgrade the quality of the diamond.

That is why we offer our unique Grow-A-Carat program. You can use McTamney’s Grow-A-Carat program for your diamond earrings and pendants or consider our Custom Design & Restyle service.

How to Grow A Diamond
 

  • Criteria:  a) The minimum size accepted for a upgrade is 0.25 carat solitaire  b) The minimum colour is H-I, clarity is SI2  c) Must have good cut and no chips or abrasions   d) The setting should be in fair to good condition  Diamond Guide
  • Value: If the original diamond was purchased at McTamney’s and you have the original bill of sale, we will apply a store credit based for the original cost of your purchase (excluding tax), which you can then use toward your upgrade. If purchased from another jeweller, our GIA Certified Gemologist will first evaluate the diamond; you will then be offered a store credit equal to the evaluation.
  • Upgrade: Some people choose to make a significant one-time upgrade, while others grow their diamond in small steps over several years. There is no limit to the number of upgrades. 


Whenever you are ready to Grow-A-Carat, we will work closely with you to determine how to achieve the upgrade that best meets your budget and your expectations.
